What is the order of channel 16 and 17's key-on registers?

You say that these last two channels have 2 key-on registers each, one for each group of 2 operators within these channels. Well, what is the order that they appear in?

It could be group-then-channel, or channel-then-group. But this is not specified. The latter allows the expression 0x240 + channel to select the appropriate key-on register for any of the 18 channels (though you need extra logic to write to 0x252 or 0x253 as well in case of channel 16 or 17).

Good point. The key-on registers follow the same order as the operators appear in:

Index	Channel
0x240-0x24f	0 - 15
0x250	16, op 0-1
0x251	16, op 2-3
0x252	17, op 0-1
0x253	17, op 2-3

Maybe there's a clearer way to notate this. You could also number the channels 0 - 19 if you consider the last four channels to be 2-op (but they really aren't).

I'd think that table is good enough.

Will add it then, thanks!
