Re: [Doepfer_a100] BBDs as CV-recorders for theremin or ribboncontroller

pitches and tones? no, no

here's what i thought yesterday

///

inputs:

* record gate
* record cv/audio
* play gate
* frequency/rate cv1

knobs:

* frequency/rate
* cv1 amount
(* maybe output amplifier gain, depending on electrical properties and 
design)

outputs:

* audio/cv

///

notes:

* slew limiter is used to smooth the output: time inversely proportional to 
the frequency/rate
* when recording (= a record gate is received and there are bucket bridges 
left to record to) the input is simply passed to the output

///

simple patch:

1 connect a-176 manual cv-source to the bbd-recorder's audio/cv-input
2 connect the output of the bbd-recorder to a filter's cv-input
3 send a gate simultaneously to sequencer start and record gate input of the 
bbd-recorder
4 tweak the filter's cutoff point with a-176 while the sequence lasts
5 now move the cable from the record gate to the play gate
6 when you play the sequence again, you will hear the recorded filter cutoff 
sequence

///

you can freely use my idea, just send me a free copy of the prototype then 
hehehehehe
