Messages 32 thru 52 / Single Drumset Only
These messages contain the same Drumset data structures as the Edit Buffer message
and are identical, with the exception of the opcode byte. When a D4 receives a complete Single
Drumset message it will automatically "Store" the data in one of the 21 memory locations (as
specified in the opcode) replacing the existing Drumset data for that slot. Its important to note
that this new Drumset data does not effect the edit buffer. For a detailed listing of the Drumset
data structure see the description under Message 1 / Edit Buffer.
