291e Feddback Osc-2
Uploaded by vgermuse on Feb 22, 2012
"Continued rudimentary explorations into feeding back the filter outs to ins on the Buchla 291e triple filter to create three oscillators. This time just the 291e and the 281e with the 281e controlling the VCAs in the 291e."
Buchla 200 Triple VCO 291e Patch
YouTube Uploaded by djangosfire on Feb 22, 2012
"So someone mentioned using the Buchla 291e Triple Morphing Filter as a VCO....
To do this you feed the output of each channel back into itself.... Then you have 3x feedback VCO's....
The VC part comes from the ability to externally control each of the filter frequency stages via a CV source....
On top that fun, the 291e module allows for things like:
- 8x stage step sequencing
- 3x VC Bandpass Filters per stage
- per stage, per VCF external modulation control via am/bw/fm
- per stage, per VCF: VCA
- and loads more!!!!
SO this vid is a really short test of these feedback VCO's, so that you can hear how rich they can sound and behave.
The sequence is created on the 291e - but I also patched the 255 into the Freq inputs to allow per VCO external pitch control - also using a Eardrill Source Selector (along w/ 077 Pendulum Ratchet & the 255 again) for sequence transposition
Other things happening (as this vid is a short 'for fun' demo) but just to be clear: you are hearing ONLY the 291e patched as a TRIPLE OSCILLATOR in the sequence . . . . . pretty cool possibilities here!"
