Pulse Feedback

Pulse Feedback from Ernst on Vimeo.

Quick and raw footage of my oscilloscope getting input from a patch in my doepfer a100 system.

Patch is roughly: 
Pseudo-Random Pulses made with 2 LFO’s feeding into an A149-1 Source of Uncertainty. 
Output (via mixer- see later) of which is filtered by an A128 fixed filterbank which is amplified afterwards by an A119 pre amp. 
Output of that is fed back via an A138a mixer into the A128. 
Feedback point is crucial for the sound! Actually this feedback functions as the resonance factor of the A128. 

Other speciality of this patch is that I actually use the A149-1 as an audio source…

Update: Also posted on the ever so cool Matrixsynth!!
