M-Audio EX-P | Universal Expression Pedal for Keyboards, MIDI Keyboards/Controllers and Supported Guitar Effects Pedals

I now have two of these for use as expression pedals (not sustain). One is for my MODX8, and the other for an Arturia Keylab MKIII. These pedals work flawlessly. Zero issues, and they stay put as well. Additionally, it's a different enough feel under your foot that yo don't get confused between this and the regular sustain pedal. FYI.

this was for my uncle and exactly what he was looking for for his keyboard

I like having the adjustment knob which allows me to set the silent point of the travel at the physical stop. The adjustment is a bit sensitive, and slightly difficult to set exactly. Also, there is a tiny bit of free play in the pedal linkage, which makes precision a bit less than I would like. The mechanism, a slotted lever and round pin, is very standard for foot pedals, and I am being overly picky about that. I am comparing this to a Studiologic VP-27, which I have nearly worn out. The VP-27 uses a nylon rack and pinion gear system, which is slightly more precise. Overall, this is a very good expression pedal, which should work well for nearly any expression pedal application using a TRS plug.

Was instantly recognized, but polarity (as noted in many other places) was inverted (toe = 0, heel = 100%). Setting switch on bottom of pedal to "Other" and in Global Settings on the Helix setting "Polarity" for this Exp Pedal to "Inverted" and it works absolutely perfectly. Stays put when set, good range of motion. Will likely buy a 3rd (if I find something to control with it - using 2 now for Vol and Wah-or-Delay Fbk). Took longer to update my presets to use this rather than an external mapped MIDI pedal than to set the pedals up. Allowed me to remove a big external controller (Behringer FCB1010 - which I loved for a long time, but it's too big for my current space) from my rig. Overall great and 1/3 the price (or even less) than other options with 100% of the functionality.

Works great, price is right.

Perfect. Remember two things... 1. M-audio/Other switch on the bottom and 2. gray adjustment knob on the side. I thought it stopped working but I had just gotten these off.

Altho this seems like a good pedal for it's intended use, and considering it's made out of plastic, it seems well made. Be aware, this IS NOT a volume pedal. I tried to use it in 3 different inputs and it didn't work in any. I saw that it said it could be used as a volume pedal and was compatible with many keyboards...It was not compatible with my Korg.

I’ve been struggling with finding a good expression pedal for my Helix. Line 6 products don’t use a TRS connector, so the ring contact of a TRS plug will get grounded and, depending upon the pedal is wired, will cause really odd behaviors (like reading 100% when the pedal is near the middle, but 0% when _either_ toe or heel is all the way down) or just non-linear expressions (like the Helix reading 50% when the pedal is only 30% rocked forward and reading 75% when the pedal is at its midpoint).If you google a bit, you’ll find forums and diagrams describing how to resolder various expression pedals to make them work with the Helix. I didn’t want to do that to my nice Roland EV-5, so I looked for something cheaper. I tried the On-stage KEP100, first, but that has a 100K potentiometer, which is too much for the Helix.So, I ordered a couple of the M-Audios (because I read they had 10K pots, like the Helix likes) fully expecting to have to rewrite them with TS connectors to make them work with the Helix. To my surprise, they worked (almost) out of the box. The only thing I had to do was go into global settings in the Helix and set the pedal as “inverted” (so it read toe-down as 100% instead of heel-down as 100%). After that, it worked great. Helix reads 50% when the pedalIs rocked half-way, and I get a nice linear progression of values as I rock the pedal back and forth.
