MPC Keypad v4.00
Get Global Parameter Command
By sending a Get Global Parameter Sys Ex command from a host device, the
user can query the settings (similar to using the keypad’s Utility menu). In this
implementation one parameter byte is read at a time from the table listed above.
Byte addresses outside of the parameter list range are ignored.
The command reads/writes a single byte parameter from the keypad, but the
data value is split and received as two (nibble) bytes over MIDI. The first byte is
the most significant nibble of the data. The second byte is the least significant
nibble of the data.
