Title: MP-1 does not change Presets correctly
Post by: Griphook on January 12, 2016, 12:31:51 PM
Heyho Guys,

I got an MP1 v2.00 a couple of weeks ago.
Also i got an Behringer FCB1010 Floorboard(stock/no unO) and a TC Electronic G-Major 2.

My Setup is as follows:
Signal: Guitar --> ADA Front Input --> ADA Outputs A/B -->G Major 2 Inputs A/B --> G Major 2 Output Mono --> Laney Head FX Return
MIDI: FCB1010 Out --> ADA MIDI In --> ADA MIDI Thru --> G Major 2 MIDI In

ADA listening on MIDI Channel 1
G Major 2 listening on MIDI Channel 16
So I got the FCB sending 2 Program Changes per Preset (PC1 [Midi Channel 16] / PC2 [Midi Channel 1])

My Problem now is:
If I press „Bank 1 #3“ on the FCB the G Major 2 is supposed to change to Preset 13 and ADA to Preset 102
If  I press „Bank 1 # 7“ on the FCB the G Major 2 is supposed to change to Preset 17 and ADA to Preset 38
Sometimes this change works, sometimes the ADA stays on ist preset and only the G Major 2 switches correctly (which it does every time correctly)

I made a small mp4 video, which I uploaded on zippyshare to show the problem better (Watch out, its around 40 MB but only 18 seconds  :dunno: ).
http://www86.zippyshare.com/v/3ghH2aUa/file.html (http://www86.zippyshare.com/v/3ghH2aUa/file.html)

If I put both devices listening on MIDI Channel  1 the G Major 2 works fine and the ADA switches very often to preset #128 and stays there.

I Hope you can help me with this issue.

Thank you and sorry for my bad English (I’m German  :) )

Greetings
Griphook


EDIT: I did not see the Troubleshooting-Category, but I think this topic will suit better in that category. So could any Moderator move this Thread? :)

What happends if you put the midi channel on the mp-1 to all?

Hey MJMP,

thanks alot for this quick answer!  :)

It seems to work, but can you explain me why?  :thumb-up:
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 12, 2016, 02:20:13 PM
No not really,i always use the "all" setting.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 12, 2016, 03:12:46 PM
Oh okay, as long as it works.

Thanks for this, but now some of the MP-1 presets show another strange behavior.
PC #19 gets me to preset #16,
PC #20 goes to Preset #29,

So the Mapping does not seem to be okay. Is there any possibilty to configure that each ProgramChange-Number equals the same Preset-Number in the MP-1?

The manual will tell you how to sort your Midi Mapping.  A good read if you don't already have the manual and are relatively new to the MP-1.    :wave: 
Check it here:

You can do a 1 to 1 midi mapping reset.

Press the STORE button and then BANK + 2 (togheter) .When it worked the display should show the command.

Post by: Griphook on January 14, 2016, 12:13:11 PM
Hey Guys,

Sorry for not answering that whole time.

thanks alot for your help :)
the Remapping worked fine :)
Can it be that version 2 of the manual is for the V2.xx MP1 and Version 1 for 1.38?
I understand Version 1 better than Version 2.

So everything should be okay.

Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 14, 2016, 02:46:00 PM
Yes that's correct.Well for me i like the version 2 better,i think it's a matter of opinion  :lol:

But working on 2 different midi channels still doesn't work i presume?

Hey R doesn't Mike B has the same setup?Maybe he could try it and see if it works on his rig?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 15, 2016, 09:28:49 AM
Havent tried 2 Channels Again. As long as other Devices only hear on their specific channel, I dont mind that problem. Maybe i could try some other channels than channel 1 for the MP-1.

I also got my unO-Chip for the FCB. Maybe this does the Job better. I will tell you as soon as i tested it :)
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 15, 2016, 01:56:07 PM
Ok keep us updated.
Title: Re: MP-1 does not change Presets correctly
Post by: MikeB on January 15, 2016, 04:06:23 PM
Yep, i have the same setup.  My mp1 listens on channel 1 and the g-major listens on channel 2.  I have never had a problem with the message not getting through.  Make sure you are actually using midi-through and not midi-out.  The fcb will send 2 separate messages with an infinitesimal delay between them.  If the ada is listening on all channels i would expect it to be responding to both messages.  As long as the mp1 PC message comes out second (which is how you have it set), it should be fine.

Hey Griphook, welcome to the depot  :wave: . I can move the topic if you like but it's ok here I recon ? Hey your English is fine although Mike and I may teach you some Australian along the way LoL.
Mike really got into programming the FCB1010, from discussions I've had with him about that journey the FCB is a very flexible unit (can do your head in though  :facepalm: , so may options). If you dig around here (check MikeBs posts is probably fastest (click his name > his profile displays > show posts)), there's some good stuff about the FCB.
I tend to use the mapping in the ADA (I have MP2) as these days I've gone very simple. So I have both units (MP2 and Quadverb) listening on ALL and I map the MP2 patch to a patch in the Quadverb and use the midi out on the MP2 > Quadverb midi in. This is primarily because I use the same dely + rev on most patches.  I have a Midverb 4 in the MP2s stereo parallel FX loop and I use the MXC quad switch to turn the loop on/off so I can dial up additional delay etc and turn it on/off (I use this very rarely though). The MV4 also listens to ALL and gets its MIDI input from MP2 through.
Because the ADA is 1 to 128 and the Quadverb is 0 to 127 I have to map to 1 less (eg ADA #10 = QV #9 etc).
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 16, 2016, 06:41:44 AM
The unO-Chip unhappily did not fix it.

Alright, I tested a few more things:


Now comes the real strange part:
I tried some other PC-Configurations just to check, how the MP1 works with the MIDI-Messages
So the setup is "FCB MIDI Out - ADA MIDI IN - ADA MIDI Thru - GMaj MIDI In" (MP1 PC1 Channel 1, GMaj PC2 Channel 2)

Attached are my Testing-Patches. As you can see, there is Bank 2 #2 which sends 2 different PCs, Bank 2 #3 sends the same PC on each Channel, Bank 2 #4 should only change the GMaj, Bank 2 #5 should only change the MP1.

Bank 2 #2 and Bank 2 #3 show the same Problem as described in Post 1 But i also face a new Problem. Sometimes the MP1, which should be just listening on Channel 1, changes to Preset 22 (which is sent on PC2 Channel 2).

On Bank 2 #5 the MP1 changes to Preset 25 inconstantly.

Now to Patch Bank 2 #4. When i press  Button 4 only the GMaj shall change to Preset 24 but apparently the MP1 sometimes catches this PC too, so it changes to Preset 24 also.  :crazy:
Sometimes the "catching-Thingy" happens on Buttons 2 and 3 , too.


Don't know why. I believe, changing the MP1s MIDI-Channel to "All" might just be a workaround  :dunno:

Very strange behaviour. I'm a bit clueless

Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 25, 2016, 01:17:25 PM
Hey guys,

i tested a bit more, but unfortunately without success.

I changed the midi-routing to: FCB Out -> GMaj2 Midi In ->  GMaj2 Midi Thru -> ADA Midi In but it stays the same problem.
Another Idea was that th behaviour depends on changing(or not) the ADA Voicing (Dist-> SS, Dist->Clean Tube, etc.), but this did not fix it either.
I even tested every single MIDI-Channel on the ADA


Have you got any other things I could check?
Title: Re: MP-1 does not change Presets correctly
Post by: Soloist on January 25, 2016, 01:23:30 PM
With my G major 2 I found it has to be last in the midi chain for all to work properly. Seems that Behringer board has a lot of issues, sold mine and got a Ground control pro. IIRC I set my MP1 to channel 16 and GM2 to channel 2. For some strange reason it was the only way it worked :dunno:

Mmmm maybe but i doubt if it will work,you could try to replace the optocoupler on the midi board.It's a PC-900,it's cheap and from what i can recall it's in a socket so easy to replace.If you look on the midi board inside the mp-1 it's the only 6 pin ic.(near the midi jacks).But like i said no guarantee.

Or like Soloist says,could be just the behringer.Do you use long midi cables?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 25, 2016, 01:49:27 PM
Hey Soloist,

thanks for the answer, but still no proper function. Put the ADA back in first place of MIDI-Cabling. Also tried your solution with ADA on PC1/ Gmaj2 on PC2 asnd other way around. Still the same.

A mate got the same setup, but i did not make it to test his FCB. But afaik hes got no Problems. But since the GMaj2 is working fine on all Channels i doubt that it's the FCB but the ADA (  :( )


I assume you do not have this as spare part in your shop? Which of these parts would you suggest?
My MIDI Cable measures about 5m I think. Got nothing to measure exactly.
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 25, 2016, 01:54:56 PM
Maybe do some testing/swapping at your mate's place before you start replacing?

Goh think i have a few lying around.Where are you from ?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 25, 2016, 02:05:51 PM
I'm from Germany(NRW). Just in case the swapping/testing won't work either I could be ready to go with the spare part.

The mate's palce a long way to travel, but maybe I'll see him this weekend  :dunno:

I just tested 2 more MIDI-Cables including  a 1m KLOTZ-Cable. So I'm pretty sure this is not a Cable-Issue :/
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on January 25, 2016, 08:49:40 PM
Hey Griphook, does the MP1 change properly bog standard ie just FCB > MP1 and normal 1 to 1 mapping in FCB. If this works, then you can run the GMaj off the MP1 midi out and map the GMaj programs you want in the MP1. I know this isn't quite what you are trying to do, but again, if it works it will give you the result
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 26, 2016, 12:26:15 PM
Hey R,

I tried this with just sending 1 single PC, and look, it works "bog standard" (I like that phrase, will keep it :D ).
But as soon as I send a second PC on a different channel the strange behaviour comes up.

Unfortunately I still don't know whether the MP-1 is not able to deal 2 different ProgrammChanges or the FCB screws them up :/

EDIT: I believe that the MP1 just receives on all channels and gets confused(so it decides just to change nothing), because if I try the following, the MP1s Display flashes the PC2-Value:
FCB sending PC1 Channel 1 (ADA), PC2 Channel 2 (GMaj2), PC5 Channel 1(ADA). So the ADA gets the PC 2 times and every single stomp on the button the PC2-Value shows up a short time before changing to the correct preset (sporadically) .
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 26, 2016, 02:55:33 PM
Does this happen even if you set the midi channel on 1 on the mp-1?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 26, 2016, 06:09:25 PM
Ups. Forgot to write that.
Yes, MP-1 is Set to channel 1 and GMaj 2receives on Channel 2

Yep  ;D

I just don't get the Mapping on the MP1 done. The Manual does confuse me :-/
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on January 27, 2016, 01:01:43 AM
Mmm, just re-read my old MP1 manual, it isn't particularly intuitive. I'm more familiar with the MP2 which gives you a MIDI change table (x = x etc). So in section 4.0 MIDI Functions, it describes how to take any external change number (1 - 128) and map that to any MP1 internal patch (1 to 128). If you press PRGM button (active), the display will show the midi pc number being sent to it, say 10, to map that to a different internal MP1 patch press MEM, scroll/select the patch number say 55, press MEM now when the MP1 gets 11 on its midi in it will change to its internal patch of 55 (which is also sent to the MP1 midi out).

Alternately, you can do the mapping in the GMaj as it has it's own mapping table eg send 11 to MP1, (MP1 changes to 11), GMaj also hears 11 (from MP1 midi through) use the GMaj change table to map that to whatever say 60 (GMaj goes to 60) (or maybe 59, if it's a 0 - 127 unit like my Quadverb). For both scenarios the MP1 and GMaj can be set to omni (all 16 midi channels).

Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 27, 2016, 04:02:56 AM
Strange!!Now don't know if this will help,but sometimes the midi stops to work and if you clear the Ram memory it starts working again.So maybe this could also work for you,or not,but maybe you could try it.The only downside is you loose all your presets (and midi mapping).

Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 27, 2016, 04:53:54 AM
Factory presets are in the eprom so these can always be set back into the RAM.So no you won't loose these,you just have to reload them.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 27, 2016, 05:05:39 AM

Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 27, 2016, 05:17:31 AM
There are 2 ways to do this

Disconnect the battery

Pull out and reseat the RAM chip.It's next to the eprom (with the white sticker) and it's usually a 5864 or 6264.Don't forget to discharge yourself ,ESD!!!
Title: Re: MP-1 does not change Presets correctly

Since the Battery is soldered  :crazy: I reseated the RAM, Reloaded the Presets, tested aaaaand, still does the same Sh** :/
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 27, 2016, 10:43:52 AM
What Version of eprom is in it?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 27, 2016, 02:40:27 PM
It is 2.00 Maybe 2.01 would work better concerning MIDI  :dunno:
For my interest, Can You Tell me, when v2.00 was the "factory-standard"?

Anyway I'm planning to buy a few things froh your Shop, but  like a Phrase in Computer games would say: "Insufficient Funds". So I have to wait for my next money ^.^
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 27, 2016, 03:00:34 PM
Well the 2.00 wasn't in production for very long.I do know that a midi dump from a V2.00 didn't work in a V2.01.
So it could solve your problem,or ...not.I can sell you one,and if it doesn't help you can ship it back.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 28, 2016, 01:41:27 AM
Maybe it would help, if I post some pictures of the interior.
I got the MP1 used and with a replaced frontplate. There are real Push Buttons instead of the standard "Touch-Panel", but all other functions as Editing/Storing Presets work well so I assume this replacement hasnt any effect on the MIDI.
Maybe the pictures will bring more clarity.

I will mail pm you about the EProm and some misc-parts.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 28, 2016, 05:28:47 AM
Another Question. Is it normal that the  MP1 (MIDI Channel ALL)  reacts to ControlChanges? It changes Presets when sending CC (Destination for the GMaj 2) either to Preset 1 or 128
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 28, 2016, 05:40:42 AM
No that's not normall at all.It wasn't designed to recieve CC's.The only way to do this is using sysex commands.

BTW can you send some pics of the front panel,just curious what they did.Could be good for other people that have a busted switch.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 28, 2016, 10:07:12 AM
Oh, that's not the answer I wanted to hear. Damnit..
My workaround for this case is: Sending the PCs for the MP1 as PC5 of the FCB. According to Documentation PC5 is sent after the CC and it seems to work.

Aaaaand I looked closely at the Display and recognized the same "Flashing"-Beahaviour as described earlier.

Attached are some Pictures of the Frontpanel and its wiring
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 28, 2016, 10:18:24 AM
And 2 more Pictures of the interior including a trace seeming scratched. The 6 pins on the right are the optocoupler If I'm guessing right.
Could this be an issue because it is connected to a pin of the optocoupler?
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 28, 2016, 11:49:17 AM
Okay that's also a way of fixing the front panel i guess. :)

What that "blob" on Z80 processor?

It also seems there have been a lot of repairs done to your mp-1.

Don't see any pics of the opto,i think you are looking in the wrong place.See pic.

Post by: Griphook on January 28, 2016, 12:05:02 PM

Wow, thats a big picture
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 28, 2016, 12:13:01 PM
Ok i see now,don't think that is problem,but you can alsways measure it out from pin to pin with an ohm meter.

Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 28, 2016, 01:41:56 PM
With Midi Board you mean the "extra" PCB with the MIDI/In/Out jacks on it?

I made so0me more fotos.
Where do I find the UART and the supporting chips? So I can give you a closer look.

There seems to be some real soldering garbage going on
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 28, 2016, 01:43:17 PM
And the other side


I really can't tell if anything is replaced except the pretty obvious Front Panel. I bought it as seen. The ebay-seller told me it would work all fine. Since I played my mates MP1 I thought there was no need for traveling through half germany and then buyed it for ca. 150€  :dunno:

Ahh no worries, I get it now.  If the MP1 is responding to CC messages (and it shouldn't), what else has been changed  :dunno:
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 29, 2016, 01:59:22 AM
I cant tell you what else has been changed. The PreOwner just forwarded me to this forum  ;D
He also stated that the wirebridges could be a consequence of the MP1-Update-Improvements (http://www.marshalljmpmodshop.net/mp-1%20update.pdf), but I dont know if anything of this concerns the two ICs?
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on January 29, 2016, 02:07:38 AM
Well you've come to the right place IMO  :wave: and great to have you here BTW  :thumb-up: Any luck doing the mapping in the GMaj ? Just to get you going, as we (well mostly you and MJMP) try to get to the bottom of what's going on.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 29, 2016, 02:50:04 AM
I'm glad to be here!  :whoohoo!: Its very nice to have a forum with people chatting about so "old" Gear. Totally love it!

Well, no, not really. ATM I'm going with the ADA listening on ALL Channels and getting the last ProgramChange. This seems to work(but it is still a workaround).  In addition Imo the MIDI-Mapping is still a bit confusing :dunno: If I understand it right, I am able to map every ProgramChange to every Internal MP1 Memory but still send the same ProgramCahnge to the Gmaj2. If this is it, it is not what i need. My needs are the following presets:
ADA 100 & GMaj 34, ADA 101 & GMaj 34, ADA 101 & GMaj 35. Yet I dont think the mapping will work in this case? But for this I would need a new Thread to not mess things up with the MIDI-Problem?
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 29, 2016, 04:18:12 AM
Well this is a G rev board so no updates required.I see they changed a lot of stuff on both the main and midi board.The bridge wires are there because they stripped a lot of traces and pads during the change of all those IC's.
The big question is,is this the cause of the strange midi behaviour or not.

R,maybe you could ask Mike to try this out with his rig and see if it works for him or not.This way we know if it is possible or not?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 29, 2016, 05:36:34 AM
So its very difficult to find this particular error. I really have no clue why all this changes were made. What are these ICs for?

Hey Griphook
(ADA 100 & GMaj 34, ADA 101 & GMaj 34, ADA 101 & GMaj 35), so prior to pedals like the FCB (eg ADA MC1 or MXC etc) to achieve what you want I would leave MP1 mapped 1 to1 and edit the GMaj change table so 100 = 34, 101 = 34, you can't have ADA 101 = 34 and 35 as in red above, was that a typo ? This is the way my rig is set up as I map the same delay/reverb patch (000) in my Quadverb to most of my MP2 patches, but as the QV is 0 - 127 and MP1/2 is 1 - 128 and I use ADA MXC pedal (which is 1 to 128) I have to reduce the PC number in the QV by 1 eg MP2 112 & QV 000 I map 111 = 000 in the QV change table.

Hey MJMP, Mike is watching this post but I will ask him to try it.

Right.  Well i haven't tried the exact same numbers but this is how mine works. 
I have 4 banks of 5 basic mp1 tones.  One bank for each combination of guitar and whether i go direct out or to the power amp.
So i have 20 presets on the mp1.  The mp1 is listening on midi channel 1.
Each of my 5 basic tones has a corresponding patch in the gmajor2.  It is listening on midi channel 2.
So the 20 mp1 patches are linked to 5 gmajor2 patches.  (Not dissimilar to what you are trying)
The fcb1010 sends the mp1 midi program change on PC1 (midi channel 1) and the gmajor2 program change on PC2 (midi channel 2).
The midi path goes from fcb out to mp1 in then from mp1 through to gmajor2 in.
This setup is working perfectly.  It sounds like your mp1 is not responding to the midi properly.  You said that it is responding to CC messages and that alone indicates to me that something screwy is going on.  I can help out with programming etc, if everything is behaving as expected.  I think your problem is more technical than that and so i prefer to leave you in the capable hands of mjmp et al.
What you are trying to do should be possible and you have done all the right things to get it to happen.  Good luck with it.

Hey Griphook

I thought about that too, but that was not a typo. It is more like a "more-gain-than-rythm-with-chorus"-Preset (MP1 101) and then a compressor and phaser on GMaj 34. But I like the same ADA Preset for lead so GMaj 35 is reverb/delay.

Mike, so you are just sending the correct PC and not use the ADAs or GMajors mapping at all?
Thanks, got it ;)


I'd love to get all things going to use all the flexiblity provided, so Im looking straight forward :)

Ok I understand now. To do what you want with mapping copy the MP1 101 to say 102 and in the GM, map 102 to GM 35 and 101 to 34. But this is to do it with mapping and a suggestion to get you up and running while we try to sus out why the FCB messages aren't getting responded to as they should. Coz what you want to program can be done with the FCB as it can send out (IIRC 5 simultaneously ?) a number of midi change numbers on various midi channels for one button press.

From previous discussion, it does sound like the midi in the MP1 has been messed with (it seems they played with the midi circuit, maybe to make it respond to CC ?) (From what i can see all digital stuff,gates,flip flops,decoders etc...). Possible fix is put it back (midi board) to bog standard ?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on January 31, 2016, 06:40:04 AM
To sum up, I got 2 workarounds until thos Whole Problem is fixed:

I Think that's it.
Yep, the FCB can send 5 PCs and 2 CCs almost simultaneously. The order of them is IIRC PC1, PC2, PC3, PC4, CC, PC5.

The Check at my mates place is still on the ToDo-List. If the result confirms the consumption that the MP1 has a kind of failure I already spoke with MJMP. He lives about 2,5 hours away from me. So I hope he can fix it then.

If it isn't the MP1 I got a problem... I think.. I dont believe the Behringer support will get as technical and supportive as you guys  :dunno: :thumb-up:

Hey Guys,

I recabled everything and I noticed that the MIDI Cables (this "outer ring")get in contact with the MP1s Chassis. My Question now is:
Could this be an issue(Grounding etc) or a cause? Or do only the pins matter?

This should not give you any problems normally.Now you can always unscrew the midi board and try to shift it into place so it doesn't touch anything.

@Mike,what eprom do you have?
Title: Re: MP-1 does not change Presets correctly
Post by: MikeB on January 31, 2016, 12:01:36 PM
@Mike,what eprom do you have?

I have the 2.1 that you sent me last year.

When i put it in and tried to restore from a midi dump from the previous eprom, it all went screwy.  Had to reprogram manually.  However, It wasn't the same set of symptoms.
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on January 31, 2016, 03:30:37 PM
What version was your previous?I guess a 2.00?
Title: Re: MP-1 does not change Presets correctly
Post by: MikeB on January 31, 2016, 10:33:34 PM
Yeah, I think so. I just went to check but i've obviously put the old one somewhere very safe and i can't find it.  It was originally Richard's which was one of the first into Australia and he upgraded it to 2.0 (if thats what it was)
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on February 01, 2016, 03:37:29 AM
I did the first MP1 upgrade available here in Oz (but only 1 upgrade), it wasn't to 2.00 IIRC I seem to recall a 1.7 ish ?? but it's a long time ago so it may have been 2.00 ?, I think by the time 2.00 came out I had moved on to MP2 (overtaken by events...). And now all my MP2s' are v1.41.

The only versions i saw were 1.36,1.37,1.38,2.00,2.01.

COncerning the MIDI-Board:
Tried to put it back "in-Place". Very tough thing to to do. It seems to be a lot of tension.
Retried the Tests. Unfortunately without success.
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on February 01, 2016, 11:18:45 PM
The only versions i saw were 1.36,1.37,1.38,2.00,2.01.
Then most likely it was from 1.36 to 1.38 that I did.
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on February 02, 2016, 09:35:56 AM
The 1.36 where one of the first units,so you have to have a really low serial nr?
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on February 03, 2016, 01:23:40 AM
I'll get Mike to check the serial number, but I bought that unit as soon as it came to Australia, the guy who owned the store went to the NAM show where they were launched, saw them, and ordered some straight away and became the importer for ADA, so it is a very early unit.  He also saw the first Andersons at that NAM show and became the importer, my ProAm was the first in the country and one of the first Tom made after leaving Schecter.
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on February 03, 2016, 08:36:25 AM
Well it be yes,these are quite rare,i know Chucky also has an early version.
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on February 03, 2016, 11:54:02 PM
Hey Mike, what the MP1s serial number ?
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on February 04, 2016, 12:57:26 PM
There's a white sticker with a nr starting with 8
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on February 05, 2016, 09:57:36 AM
Just a note besides. My serial Number is: 814927

Is there any Key to "decrypt" the exact date, or a period?
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on February 05, 2016, 10:22:49 AM
No not really,it's all guessing.Ada made around 25-26000 pieces.
Title: Re: MP-1 does not change Presets correctly
Post by: rnolan on February 05, 2016, 09:33:59 PM
Serial of Mikes MP1 is 803586
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on February 06, 2016, 07:30:36 AM
That's an early one but i doubt it's a 1.36 ,guess it was more like a 1.37?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on March 11, 2016, 08:01:31 AM
Hey Guys,

I didnt' forget about you.

I managed to get over my mates place to test with his MP1 v1.38 and what came out?

His MP1 switches faster, better and does only react to signals send on its own MIDI-Channel. CCs are passed through without any problems.
So my next step would be to give my MP1 away to you MJMP, like we said via PM.

I don't know what it is or how it comes but Im a bit frustrated about this because I could live with the extra work of Mapping but not with the wrong consideration of CCs which often screw up the current patch.
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on March 11, 2016, 08:42:03 AM
Well that's strange,did you change anything in your mp-1,like swapping the eprom?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on March 11, 2016, 10:19:03 AM
Nope, I didnt. If I had done it you would know  :thumb-up: :)

But as I said, my Mates MP1 works pretty damn fine(even better sounding) and my still got the problems
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on March 11, 2016, 12:04:48 PM
So what did you actually do?Did you just try your pedal on his mp-1?
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on March 11, 2016, 01:34:36 PM
Yep, exactly.
I configured a few patches exactly the same as mine und also used my GMajor 2.
I used my FCB to switch everything . All was working flawlessly with his MP1.
Title: Re: MP-1 does not change Presets correctly
Post by: MarshallJMP on March 11, 2016, 02:08:05 PM
Ok so now we are sure it's something in the mp-1.
Title: Re: MP-1 does not change Presets correctly
Post by: Griphook on March 12, 2016, 09:12:35 AM
I will contact you, as soon as I was in the studio with it :)
