What if you invert Loosen and “Step on” values?
Loosen value: 127
Step on value: 0
Hi,
I have an M-Audio EX-P that I never use but I remember that it worked when I tested it. Here are my settings in the CubeSuite app (they are accessible through the expression pedal icon, not in the Advanced Custom Mode) :
Channel : 3 (I don’t think this matters)
Data 1 : 0
Loosen value : 127 (as @Zavorra suggests)
Step on value : 0
Also, the TRS port (next to the expression pedal icon) is set to “Expression pedal”, not “TRS-MIDI”.
With the settings you suggested, the Source Audio dual expression sweep now sends midi values from 1 to 8. Which is an improvement, at least 
It seems like there’s something simple I might be missing, but I can’t seem to put my finger on it.
Edit: I hope it’s not a firmware issue, because the SincoOTA app is giving me a headache
And I’m starting to eye the Hotone Ampero Control footswitch…

Maybe you got a broken unit. Can you return it or have it replaced?

Unfortunately, I got it secondhand. That it wasn’t too expensive is some consolation
OTOH I think that there it may be due to a lose solder point on the trs connector. If you have a friend with some basic soldering skill it is not too hard to check for it

The internal jack in the Chocolate is shielded by plastic. I could probably take a razor to it, but I ultimately decided to purchase a device to turn expression input into USB MIDI and bypass the Chocolate. Even if I got the expression pedal input working, the companion app needs inprovement.
However, I do still intend to use the Chocolate for its footswitches and look forward to the continued development of the Gossip plugin
