Hey mjfan123, seems to me you are doing everything right  :thumb-up: (and it should be easy), first guess is it's the RMM, it should hold the channel assignment.  Maybe it needs a new memory battery (if it has one  :dunno: ) but it should save the change (unless your missing something in the manual (but it doesn't sound like you are)).Do you have anything else that sends/rec midi (eg a keyboard) just to test that 1 - your MP1 is receiving correctly (I suspect it is), and 2 - The RMM isn't saving channels and thus not sending sending midi instructions.  I'm thinking the RMM is defective and you should return it, but they are going to want to be convinced it doesn't work.  If there is a method to factory reset the RMM, try that (I'm not familiar with the RMM so not sure how complex it is or can be set up to be).

I think this is a defective unit, luckily I got it from Guitar Center Used so I can return it. I tried to reset it, but got ERR code 15 and not ERR code 0 like it should have.

It's not remembering channel assignments, etc. Plus I'm not liking the look or layout that much anyway. I ended up buying a used Ground Control Pro on Reverb for a good price, which I hope will work better.

I'll let everyone know, Thanks.

Hey John, if you want to switch between a few preamps I'd suggest you use a small/medium mixer (eg a Eurorack UB2442 or later equivalent).  So all your units come into channel pairs 1/2, 3/4 etc keeps them all stereo.  Then use 2 FX sends to feed you Fx unit (L/R) and bring it back into a channel pair or 2 returns. So this will mix all your outputs together and let you use the same Fx across them all. Obviously Mixer out to amp > cabs.So the trick will be switching to each preamp input. You could use a small custom switch, I modified an old Peavy channel/reverb switch to be  an A, B, A+B by adding another jack and re-wiring the foot switches.  Also there are A/B switches available.  A simple solution would be mount 5 jacks and 4 foot switch buttons, so 1 jack is guitar in, the other 4 feed 4 different preamp inputs and the buttons just turn that feed on/off (so you can feed them all individually or in any combination)
However, if you do a parallel split of the signal to each preamp, you could do your switching by creating a bunch of patches on each preamp and mix and match which preamp(s) you want at any given time.Or you could do it switching preamp output pairs, easiest way to do this would probably be use a digital mixer you can control via midi  :dunno: to mute/un-mute channels

Hey Luke, you may also want to follow this post (http://adadepot.com/index.php?topic=2156.0), it may become the blue print noise mod for all old MP1s  :dunno: , albeit he hasn't finished yet.

sorry it took so long to reply, really busy at work lately, I work in hvac... I play a lot of maiden, dream theater style stuff and occaisionally some satch and vai
I have a simulclass 290 and a triple rectifier sitting around , but was hoping on going back to my ada stuff so I can use them with a switcher to go through a couple pre amps and have them routed through an effects unit or two..I've got a lot of stuff sitting around, some old digitech 2112 and a 2120 , valve fx and a few more , but only one art effects unit, a nitro I think its called, just want to use it for delays, reverbs and pitch shifting etc... actually I have 2 mp1's and 1 mp2
so I sure would like to use all 3 in a switching set up if I can figure out how to do it with no noise....im looking for someone locally that can do the mods for me, I have a guy that does a lot of 80's type stereo repair that I am sure can do the work, I just have to get in touch with him to see if he has time, if not I may have to send them out to someone , I live in Illinois close to Chicago, if you happen to know anyone that would help a lot
thanks for any and all help
John

Hey RG, I use the MP2 cab sim outs with the studio rig.  In my live rig I take the MP2 A/B to ch 1 & 2 and the cab sim outs to ch 3 & 4, MB1 out to ch 5. When I use the 2 Messa P112 bass cabs (12 + horn) I use the cab sim channels (or MB1 for bass guitar).  When I use the ADA split stack(s) I use the MP2 normal outs.

I am having the same problem. OP did you resolve the issue?

I bought a used Rocktron midi-mate from Guitar center, and am trying to follow the instructions from the manual to change the midi channels. On the pedal, I change it to channel 1, but it doesn't save, it goes back to being off when I scroll back. Maybe it's defective, in which case I will return it to Guitar Center.

I changed the channels on the MP-1 to both all and channel 1. The MP1 is in excellent condition and everything appears to work(just bought it from Ebay a few days ago.) And this didn't work to change presets.

Please advise if I am doing something wrong. This is my first experience with midi that's not a midi keyboard.

Thanks
