With old music maker version who had the VST independence from Yellow Tools , it was possible to define some keys who launch a "riff" midi file

The instruments from Magix Music Maker use normally the banks from Yellow Tools , so i guess it should be logical that it s possible ( probably in modifying the file folders with Magix Music Maker instruments

But i have not found the way to make something similar . .

Probably the solution is tricky , but has someone an idea ?
