"How about adding an extra OH track and set the Mix knob to 100% source audio/0% samples audio to hear the Source Audio only? If you like a clear view of the waveform you could set the Velocity Threshold to 127 and the Match Threshold to 100% to make sure nothing is triggered and no Events are visualized. Would this help?"
definetly...thats it,
now for the solo shortcut thing (sorry to bother you again)
as i use solo (Mostly) for the snare to find real low ghostnotes,it would be comfortable (option in settings maybe), if tracker would pan automatically to full left (sound file) on selecting solo of the tacks (less mouse messing, lazy fart here)
have a nice weekend
