May 18: FSH1 Feedback Multitrack by C C O published on 2018-05-31T19:06:32Z I need to use my Cwejman FSH1 frequency shifter more often and I noticed that I never put it in a no input feedback loop. After patching it up, I decided that it would be fun to try and multitrack it a few times to layer and cut some fun parts. Here is the FSH1 Feedback Multitrack. For the audio feedback loop, the mix output of the FSH1 is patched to channel 1 of a VCA4MX first, basically just to act as a mult. Output 1 goes to a Doepfer A199 spring reverb, which is routed to the FSH1 to create the feedback loop. The 1 + 2 out of the VCA4MX is used for recording and firstly goes to channel 3 of the VCA4MX for some VCA action and from there to the SPH2. The L + R outs of that are then used for recording in stereo. In terms of modulation, a RG6 is at the core of the patch. The high S/H out is used to modulate the FSH1 carrier frequency. The clock triggers a CTG-VC, which opens the final output (after the feedback loop) on channel 3 of the VCA4MX. On the RG6, some (internally normalised) self-modulation from the random saw to the RG6 frequency is used; additionally, the inverted random saw modulates the CTG decay so that the envelope gets shorter as the RG6 clock gets faster. Furthermore, the random saw modulates the rate of the internal SPH2 modulator. Finally, the RG6 gate output is used to clock a D-LFO S/H, which modulates the down / up mix of the FSH1. That’s the whole patch, for the tracking I almost only play with the FSH1 input level to try and control the feedback action (rather a difficult balancing act). Sometimes, I sweep the FSH1 carrier frequency a bit. It’s multitracked six times and I cut out some parts after recording each take. Finally, I added a subtle RE201 return track, plus some delay, reverb, EQ and compression in Ableton to bring it together. Hope you enjoy it and cheers!
