Title : Getcaps
Author : tonyg
Posted : 1+ years ago

Description : Getcaps is used to check the device capabilities of the primarydevice selected for use in Bmax.
This is DX7 only. You'll need the DX7 docs for many of the fields although some are commented and some are self-explanatory.
Hasn't had extensive testing so feedback, comments and improvements welcome.
