HELLYA...Is there a way to set-up Sonar to catch the tempo changes from a sequence (with multiple tempo changes) that comes from a drum machine?...
Tempo changes are part of what's saved in a MIDI sequence. But that kind of global data is ignored if you import the MIDI sequence into an already existing project. You need to Open the MIDI file, then build a project from there. If you do that, all the program changes originally done will be retained.
