I'm using an IK Multimedia AXE IO Solo USB interface with a Moog expression pedal with Tracktion Waveform DAW. The AXE USB interface converts the expression pedal input and provides MIDI signals to the DAW. The problem: When I use a wah pedal plugin in Tonelib GFX the wah pedal position is either at 0 or 100 - nothing in between. The wah function in Amplitube works correctly so the hardware and interface is working correctly. I can also see that the values sweep in the MIDI controller lane in the DAW, so there is a range of values hitting the wah pedal. I used the the controller learning function in Tonelib to assign the controller to the wah pedal position.
