Cool, I had an idea about trying something like that once, but using a turntable instead of a pizza box...

Hmmmm, a optical cartridge.... How many wires do those sensors in optical mice need? you get 4 on a turntable but the grounding might muck it up. Probably much lighter on the CPU then analysing one of those timecode records, at least. BTW; That company that did GuitarHero trademarked "TurntableHero" a while ago, or so I read. That might result in interesting controllers. My Beatmania toy turntables only sense movement and direction, not speed so I could use some improvment there. Kas.

Along these lines, I thought I'd share a recent post to the XWAX developers list (its not chuck related, but maybe someone wants to take some inspiration, and pack the XWAX code into a chuck ugen):

Hey!

I just did a quick hack of wrapping the timcoder.c code into a flext external, so the timecoder can be used in pd or max/msp (dunno about v5) and be used for stuff like scratching videos and alike. This is a very small and easy hack but it works http://karhumusic.sesser.at/vinylcontrol.tar.gz Documentation is in the tarball as vinylcontrol.pd patch with some comments. I left the binaries in the tarball as some might have problems building the external (... next time I should not forget to delete the binaries with debug symbols, heh...).

so long... Niklas
