4.4 Register group 0
Register group 0 is the most heterogeneous one, it needs some subdivision.
•
Addresses 00H...0FH contain couple of general (not channel or operator specific)
settings and the status register. Most of the registers are not in use.
•
Addresses 10H...1FH contain channel specific settings. They affect the channel as
a whole, all operators at the same time. The 3 least significant bits of the address
are the channel number.
◦
10H...17H = algorithm, feedback, output channel
◦
18H...1FH = vibrato, tremolo, echo control
