Title: Lexicon MPX1
Post by: Soloist on April 09, 2016, 10:00:43 PM
Scored on one of these today for next to nothing! Slapped it in the MP2's loop and it sounds pretty damn good! :whoohoo!: I was looking for a MPX G2 but I couldn't pass this up, looks brand new! My only bitch is the lag time when switching presets. Those Lexicon reverbs are lush as hell :bow:

Great score, wouldn't mind a G2 myself.  Lexicon reverb is my favourite, my first experience was with the Lark 224x in the studio, great reverb.
So is the preset lag in the MPX ? (I'm assuming here you have v1.41 EPROM in the MP2 and have set it to "fast" program change (it is a MP2 setting BTW (in case you haven't tripped over it before))). Maybe there's a firmware upgrade for the MPX to speed up the patch changes ? (as was in MP2 v 1.41).  Also does it make any difference if you use the MP2 midi out rather than the through ? just thinking out loud here...

The MPX1 is known for the *extreme* lag when switching presets...nothing you can do about it.
Best workaround is to *build* one big master preset and then assign various MIDI CC to parameters and map them to switch/alter when switching presets.
The FX-quality in the Lexicon is awesome!

Just checked Bob Stellon's Lexicon pages; no firmware upgrade since V.1.1, and he no longer stocks it: http://www.stecrecords.com/?RecordId=417 (http://www.stecrecords.com/?RecordId=417)
Don't think he'll do any more upgrades on either of the two devices; had a chat with him last year about possible mods on the G2..

That's Exactly what I am doing. 4 main patches, 1 for cleans, crunch, hi-gain and solo's. Seems to be the only work-around. Of all my rack gear this is the only piece with lag when changing presets, not a big deal my ground control pro will handle all the CC mapping.

I also have one and when you switch there is an option that the sound doesn't go away just the effect,but i can't rember how or what.It's explained in the manual somewhere.

I think your are talking about the program load. Manual or automatic. In auto mode there is a brief time out while the patch loads. Also the setup load and setup store function can be used to store up to 5 configurations for quicker access.

No don't think so (it's been a long time since i used it),it had something to do with bypass mode were you could select no sound or just dry sound when switching to another preset.

I will look into that. Thanks!

Does a lexicon MPX2 have intelligent harmonizer?  Do you know Soloist?

The MPX-G2 has an intelligent harmonizer

I don't think there is a MPX2 ,there is a MPX200 and also an MX200?

Hey Gang,

   I believe all the Lexicon gear has a lag in the program switching when it comes to MIDI. I own several Lexicon rack units, and the only way I overcome this lag is to use my Voodoo Labs Ground Control with them.
   I assign the Lexicon racks their own MIDI channel, and that does the trick.

So how does that solve the lag Harley?

Maybe the MPX is slow to decipher the sysex stream to work out what's intended for it ? So if you give it it's own channel, all messages on that channel are for it ? just a guess.

The other problem with that is memory. The reverbs run on a separate chip so you can always run a reverb. The other chip does not allow you to run very many effects on it at once. I can run a great pitch shift but no delay or chorus. Or a great delay but nothing else. So I paired it with my MP2. I run it in the MP2's loop with a 25% mix. I use chorus and other effects from my MP2 and use the MPX1 for the three things the MP2 doesn't have, i.e. Pitch, Delay and Reverb.

Has this improved in the later units ? I was looking at the MX300 yesterday and it looked like a good thing to buy but I'd want pitch shift and delay as well as reverb.

I'm not sure how it does it, I've just noticed that when I assign the Lexicon gear it's own channel and give it program changes directly, there isn't any lag in the effects switching.

That;s what I like about the Ground Control. It can be set up to control 8 MIDI units on their own individual channels independently. I use the odd numbered channels with my system, to control multiple MIDI units in the same rack. This in itself eliminates the natural 8ms lag that you get in a daisy-chain MIDI setup.
