Hey, we ran Syntax Demoparty (Australia) this weekend and had a few interesting things come out of it.
The first item on this video is "work in progress" but coming along pretty well.

While the replay function is the main feature at the moment, eventually Sanity intends to add support for MIDI. I'm going to request a feature for "loop points" so you can call back (via MIDI) timed loops of audio to the SID which will make it a perfect live performance tool for using a real SID chip based to data capped from a real tracker. But there is a feature in dev for playing the SID live with a synth / via DAW MIDI output too.
EARLY DAYS in dev, but thought I'd post the vid. Also, lots of C64 stuff in here. Check out those trading envolopes from the disk mailing days!!!
