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

It works great!Inexpensive, adjustable knob, and 2 settings on the bottom.Heavy duty plastic, but not cheaply made.

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.

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.

Works well with the Boss Katana 100Mk2 with the GA-FC EX Foot controller. Good build quality and looks sturdy. Works as a volume control and wah. I highly recommend if you’re on a budget.

Purchased primarily for wash use with Katana 2. Does function but end of travel seem wasted (at least in one direction, effect reaches saturation with travel to spare). I'll try to see if there is a way to modify the MIDI range to suit.

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.
