Schippmann CS-8 VCF-02 Multimode Filter

"In Part 1 of the video (00:00) we are running a series of chords from an Analogue Systems rs370 Polyphonic Harmonic Generator sequenced via MIDI through the Schippmann CS-8 VCF-02 while experimenting with filter combination settings accessible by toggling the Slope buttons on the VCF-02 front panel. Cutoff modulation is coming from the Cwejman PH-4 and manual tweaking.

In Part 2 (00:35) we are using the same rs370 patch with +20dB of drive on the VCF-02 input to add some distortion and harmonic flavor to the patch. Cutoff modulation is coming from the Cwejman PH-4 and manual tweaking.

In Part 3 of the video (01:21) we are using the Analogue Systems rs370 with the rs375 Expander Module in analogue realtime mode. The Cwejman D-LFO is Frequency Modulating the CV1 (Cutoff) parameter while the Cwejman PH-4 is modulating CV2 (Cutoff) of the Schippmann VCF-02 filter."

Critter & Guitari Melody Mill with Cwejman QMMF-4

"00:00 - The Critter and Guitari Melody Mill is driving the Cwejman D-LFO as a dual oscillator, and two pinging channels of the Cwejman QMMF-4. The Melody Mill's trigger out is pinging a Mutable Instruments Tides and Cwejman CTG-VC for envelopes. The 4 voices are mixed in the Mutable Instruments Frames.

00:35 An arpeggio sequence has been recorded into the Critter and Guitari Melody Mill which is sequencing the Cwejman D-LFO as dual oscillators, and pinging 2 channels of the Cwejman QMMF-4 in RES mode. The Melody Mill's trigger out is pinging a Mutable Instruments Tides and Cwejman CTG VC for envelopes. The Cwejman PH-4 is frequency modulating the Tides which oscillates from control to audio rate. We manually tweak the Melody Mill's clock speed, arpeggiation range, and pattern."
