Wannsee by Knut Graf published on 2021-10-04T03:05:08Z Playing a pair of near-sine wave voices in a chord sequence, harmonically layered by bit shifting. Vimeo version: https://vimeo.com/622091795 Patch Notes: Qbit Chord oscillator provides two voices on base note and 3rd output, and a 3d voice from the mix output. A 4th voice is a clocked delay by Disting, fed the three other voices, attenuated through a mixer. Maths provides attack-decay envelopes for voices 1 and 2, and an additional control signal that is a negative-polarity sum of these two envelopes, and an inverted version of the sum. Voice 3 gets its basic envelope from the Doepfer VCS Slew Generator. Voice 3 is also attenuated by Math's negative sum CV ducking it against the other two and it is modulated by a copy of the delay signal from voice 4. This envelope shaping is done using a combination of a low pass gate and a low pass filter. Math's negative sum CV also modulates delay feedback. The inverted sum CV, with attenuation, moves the wavetable on Chord oscillator, adding a small amount of overtones during note play, like opening a low pass filter. The chord sequence is controlled by Sputnik voltage source CV sequencer, driving a 10-step chord voicing sequence and a 5-step chord quality sequence. The Sputnik Pulser section provides CV for the master clock speed, feeding Tempi clock module. Tempi provides a fast master clock, and slower derived clocks to run the sequences. The main note sequence clock is split into two half-speed clocks, with one of them running though a custom digital delay patch on Torcido to create swing. The actual note sequences and their triggers come from Klee, the bit-shifting sequencer. Pitches are quantized to a pentatonic scale. Slopes on voice 1 and 2 are controlled from Addac VC transitions. Output from ES-8 USB audio interface is captured by Modlogr, my headless recorder on a Raspberry PI. Ableton Live adds some equalizing, a little compression, delay and reverb. I'm playing the Klee sequence, and the envelope slopes on the VC Transitions slider. Genre Electronic
