Hi Bernie,
All the features of vArranger can be assigned VERY easily to :
- any PC key
- any midi controller (buttons, knobs, sliders, pedals....coming from your MIDI equipment)
The assigning by midi learn is very EASY :
go on the controller page.
1) select the feature you want to assign
2) click on your controller button.
It's Done.
Let me know if you need any more informations
Dan
