When I still used Windows and Guitar Pro, i liked to use another software sampler with GP. I worked it out with multiple MIDI outputs. Now i'd like to do it also with Mac. But the problem is that if I stop playback when there's notes playing through sampler, the sound won't stop (it keeps playing the "stopped" note forever). I have tried couple of samplers (Reason, Kontakt) with same result. When using Windows-version, there's no problem at all. OS X's default MIDI sequencer works too. Any tricks, fixes, workarounds?
