How many sound channels are there on the Genesis/MD's Z80? Just the Z80, not the YM2612. I'm writing some music & wanna make sure I'm not cheating.
Here's the song I'm working on:

I used 4 different square tones, like those produced by the Z80, but with the way I wrote the song, it would probably translate more to 5 or 6 channels on actual hardware.

The Z80 doesn't have any sound channels. None in the SMS and none in the MD/Gen.
If you use the sound functions in the Gen's 315-xxxx VDP, you get 3 square waves + 1 noise channel.

Ohhhhh that's right. I forgot. You totally answered my question, though. Thanks! Did the Genesis have access to any other additional square waves, or was everything else strictly FM?
-
IIRC it had 6 stereo FM, 3 PSG and 1 Noise channel = 10 Channels in total.

One of the FM channels can also be configured as a PCM channel for digitized sound effects.

Ah yeah, the MDs weakness. Only one speech sample at once.
