hello all and,
thanks for this hugo
using amplitude modulation is a very interesting concept for what i'm planning...
i have a gig here in sheffield on may 30th, and was absolutely determined to use my MOTM, without messing around with midi
the current plot seems to be serious drum loops out one side of a CD and control signals out the other - original the control signals were just going to be trigger impulses, then i got the daft CV idea, but AM and an envelope follower seems the way forward
i'll get back to the list next week when i've had chance to mess around with this...
cheers

(oh boy, got reherse / get of my arse and finish cabinet / flyers / etc / why did i agree to this..?)
Morton Subotnick has composed several pieces using such a system .
Too early for cd tho, he used a stereo Nagra portable recorder .
Several cv/gates would AM modulate sines by way of vca's . The
control voltages would be recovered using several BP filters,
rectifiers and envelope followers . The playback box (built by
Buchla) would both interact with real time audio from the score
played by the musician, and the cv's coming from the recorder . I
witnessed a performance for cello and box in the early 80's . Can
you say weird :)
