MIDI program design is literal idiot level one billion. Dear vintage rack users, PLEASE STOP RECOMMENDING THIS POS!
So some of you guys know that I'm currently in the process of building a modernized Bradshaw-style rack rig. I've been in search of a perfect rack unit that will provide me with stereo detune, hoping that it'll not only compliment my Boss SE-70 well, but I was also hoping to avoid having to consider buying a Fractal Axe-FX later down the road.
Lexicon MPX-1 just proved me wrong on that. Here's why this POS rack unit is terrible - the user presets can only be saved in presets 201-250. That should be enough right there because most if not all MIDI controllers can't reach any further than 127 program change commands, but it gets worse. When you try to map out the MIDI programs so that different program changes load up different presets, guess what? The MPX-1's MIDI IN port magically dies and refuses to load up the requested programs! WTF?!
You know, I've dealt with bad purchases of vintage rack gear in my time, but the MPX-1 is a major step backwards from the legendary PCM rack units. In fact, the MPX-1 should be labelled the "guitar rig murderer" because it frustrates people to the point of insanity!
Sigh, so now I gotta decide on whether to risk becoming a laughingstock in front of other rack rig users by going with a Boss MD-500, or I gotta overhaul my entire FX Loop for a Fractal. What I am NOT gonna do is risk another cent of my hard-earned money towards another vintage rack gear. EVER!
And Lexicon, please change the name of this product to something else, like "Lexicon POS-1, which stands for Piece of Shit 1," 'cause at least that'll be a lot more honest.

In this Rig Rundown by Premier Guitar, Lexicon MPX1 can be seen at 4:22 in Mark's rack.
In this article, Joris says, “I bought this a while ago; again it was used on the track MPX309 - hence the reason it’s called MPX309. I haven’t used it at all really after that but it being on that record meant that it paid for itself.”
"Then I have a Lexicon MPX1 effects processor, which I use for specialty pad sounds when I have a volume swell with all kinds of delays happening."
This GuitarGeek rig diagram mentions that Reb Beach used a Lexicon MPX1 multi-effects unit in the effects loop of his dirty amp. He used it for a short slap-back delay around 2001 when he was touring with Dokken.
In the pictures of Chicane's Modena 1 studio in the article, the Lexicon MPX1 can be seen as top device of the left rack on the floor. It can be identified by the prominent block of 9 white/light buttons, the traces of the white "Lexicon" print on the right of the panel, and very faint traces of the blue decoration print.

Graeme Norgate is demonstrating his Lexicon MPX1 which he used during his Free Radical Design days and this will showcase a couple of presets and patches shown in the video.
“Ok, Saraya days (live) I was using the classic ADA MP-1 setup with two Bedrock 4x12 slant cabs/30 Watt Greenbacks in both. Main axe was that Lake Placid Blue ESP strat with a Seymor Duncan in the bridge and a Kramer Sustainer, flip-flop purple/blue. FX were a straight up Lexicon MPX-1 through the FX loop.
When we did the first record, I tracked with that rig (at Bearsville Studios in NY). But we did all the overdubs at Studio-1 in Austin, Texas and Jeff Glicksman, who was producing, brought in this Mashall Plexi that just leveled me. Used it on everything except ‘St. Christophers Medal.’ That track was recorded near 2:00 a.m. and we were drunk, tired and who knows what else, so when the solo came up during basics, instead of staying with the rhythm part, I just went for it. The next day, even though I wasn’t nuts about the tone, I LOVED the solo, so it stayed.
When we did Blackbird (and thank you for the praise... I still love that record), I needed to raise the bar a bit in terms of layers and tone. So I bought a late ‘70s Les Paul Jr. and started getting used to the way it changed my playing. I ended up writing the entire record on that guitar. I did all the demos on my home studio (Korg M1 and Tascam 8-track) and Sandi wrote most of the lyrics in the studio. Funny thing is, we recorded that record just outside of New Orleans and the studio had great vintage gear. So I ended up using a Tele on a LOT of those songs, the Jr., and a Fender Twin, my ADA, and a Roland Jazz Chorus all running together and coming up on six faders.
Danger Danger was another situation like that. The studio had this old Laney Pro-Tube Lead that sounded dope so I used it on the entire record, with my Lexicon MPX-1 and the Blue ESP.”
