Windows 7, Studio One v3, Similar Problem with my Roland A-88. No Sustain Pedal, Expression Pedal or tone bending/modulation stick. The keyboard does play the instruments, just no MIDI Peripherals function. I do and F3, go to External tab and at the top left of the screen after doing a MIDI Learn I can see my pedals all working as I select each one, I can see their names and changing values as I move them. they just have no effect with any of the midi samples in the virtual instruments. My Keyboard driver is correctly loaded and functions perfect in Cakewalk Sonar and in ProTools 10. I opend a support request to them and I have submitted my machine profile report to tech support. When we solve the probelm I'll post on here the solution. If you figure it out first let the world know. I'm suspecting they may have a bug and may need to write a patch in the code?
