While learning I have MPE disabled but still use the x axis for finger vibrator. Having an issue with with losing pedal and slider function when I first turn on. To reset I go into the editor and enable MPE and then disable again and the function is restored. UPDATE: Working with tech support but I noticed the problem didn't occur if I have MPE enabled. Have to tweak my vsts as MPE sends data out on multiple channels and the ones I am using respond differently when MPE is enabled as they are non MPE vsts.
