I've seen it mentioned a few times, but never with a definitive answer... There's just a lot of general weirdness when importing Guitar Pro-created MIDIs into Sonar. Not sure about other DAWs. I'm tracking keyboards with Absynth 5, using the MIDIs as a reference, and my fucking settings keep getting changed when I play back certain parts! Usually the volume/panning in Absynth... And in Kontakt, when the piano comes in it resets the "chord" knob on the earlier choirs (different channel), making them play garbage. The parts I record in Sonar are fine, but the reference MIDIs are not. I've already deleted all non-note events on those tracks and it keeps happening. I can't even find the settings that are being changed sometimes. Between that and the stuck keys/vibratos when stopping playback.... I'm going nuts here.
