Re: [sc-dev] Ugen creation q

[crucial felix <felix@xxxxxxxxxxxxxxxxxxx>]

this single ugen should be an LFPulse oscillator
it takes an input, sets its frequency to the value of the input,
and changes its frequency once everytime its own trigger happens.

it can't be done by patching ugens together because you can't patch its
output into its own input.

since neither the nose nor the butt exists yet,
it can't sniff its own butt.
