Parameter base address
With the DR-770, the parameters can be transferred either by bulk dump or by individual
parameter control.
By individual address, each parameter can be received and transmitted individually.
By bulk address, the plural parameters as one group are received and transmitted.
By individually, only current Drum kit(selected)parameter and global parameter can be
received and transmitted.

*1 Instrument number is transferred by dividing value 00H - FFH into 4bit MSB and 4bit
LSB.
*2 Pitch is expressed -2400 as 0000H and it is transferred by dividing value into 2bit MSB
and 7bit LSB.
*3 With combination of Polyphony and Assign Group, A.TYPE is defined as follows.
