Hi, I just bought the iRig Keys2 Pro and tried using it with my old sustain pedals. I have two - one no-name and other is M-Audio, but don't know the model - both have polarity switches so I set them to open, connected to the keyboard, then connected the keyboard to computer, but sustain is not always working.
I started analyzing what come out of the device in Ableton and I see that sustain is sporadically switching on and off while I hold my foot on it. Both pedals express the same behaviour.
I have a couple of MIDI keyboards (M-Audio Axiom, Novation 25SL MkII and even Yamaha piano) - the same pedals work fine on those devices.
Could it be a software bug (not filtering out analog noise of the switch)? What could be the solution?
