Happy E-tune (SidStation)
The "happy little E-tune" posted previously ([2.5 MB .mp3]--eventually it'll get a real title) is reinterpreted here on the SidStation synth: [3.1 MB .mp3]. Also working on an extended remix of the Sid version, with drums, etc.
The Sid isn't truly polyphonic, so in order to have it play several melodic parts simultaneously you have to overdub them (digitally). This is a pain in the ass.
