Hi,
Please try VMPK (Virtual MIDI Piano Keyboard) http://vmpk.sourceforge.net/
I'm the author of this software that works in Windows, Linux and Mac OSX, but never tried to use it with Pro Tools. Good luck!
Regards,
Pedro
I actually downloaded vmpk a while back, but can't figure out how to set it up (to work with the sample programs in Pro Tools.. specifically BOOM and XPand! 2). Do I need an intermediary app to link vmpk to the sample programs, as a MIDI controller?
Just yesterday I downloaded midi_patchbay, Jack and midiStroke. I couldn't figure out how to use them or what they're for; I'm assuming one (or all) is the intermediary app.
I've never used MIDI before so the terminology is foreign to me, as well as the procedure to set it up. I'd just buy a MIDI controller, i.e. keyboard, pads, etc., but I don't have the cash.
Thanks for vmpk as well as your help now.
