> Are they any good? I noticed they don't have a sine wave.

The audio demos on the site sound promising. I havent quite finished
building mine yet, but I'm 99.9% there. I have like 12 parts left to
install. Mouser is backordered up the wazoo! :/

Looking at the architecture, its similar to, but better than the Roland
SH-101. but with 2 oscillators. As far as sine waves go, there are two
possibilities:

1) There is a waveshaper module that is supposed to turn a saw wave into a
triangle. Low pass filter that, with keyboard tracking(KEYB) and you have a
pretty close sine wave.

2) Not sure if the VCF can be pushed into self oscillation, but if it can,
you have a sine wave there too. Its an old SH-101 trick. And with keyboard
tracking, the pitch of the sine wave will follow the midi notes you play.
