Star Tip 2

That's actually the routine that goes under the 'Tim Follin 3ch' title in 1tracker, added there good 11 years back. To my knowledge, no one ever used it for a song.

It is a three channel engine that has a specific limitation in that three channels share the same exact note length and 'volume' (duty cycle) envelope. I.e. you can't play a long note and a number of shorter ones at the same time. It is also prone to very severe detune, so all note combinations has to be tuned up by the ear to sound properly.
