Patch Notes #6 - Korg SQ-1 As Eurorack Sequencer

Published on Jul 18, 2016 Voltage Control Lab

"Patch Notes for our recent video on using the SQ-1 as a USB MIDI to CV Converter. However, the SQ-1 is not performing that function here, instead sequencing and clocking the Eurorack system.

The SQ-1 is sending pitch and gate CV from the channel A outputs to the Make Noise 0-Coast, which is playing the 16 step plucky melodic riff. The channel B gate CV out is routed to the Varigate 4, which is sequencing the kick drum generated by the Malekko Dual Borg filter (see our relevant tutorial video).

The Sync Out is routed to the Make Noise Tempi, which is in turn sending clocks to the Make Noise René, Brains, Wogglebug and finally, the Ornament & Crime (in Piqued mode).

René is sending pitch CV to a buffered mult, which splits the signal to the Make Noise DPO playing the bass, routed through the MMG and Optomix, with one looping LFO from the Malekko ADLFO controlling the filter cutoff.

The mult also routes to Mutable Braids in WTx4 mode (tuned a perfect 5th up from the bass) which is playing the chords/pads. Braids Timbre is being modulated by an internal LFO, part of the Bees in the Trees alt firmware.

Brains is clocking Pressure Points and Analog Memory, 5 channels of which are modulating the Noise Engineering Basimilus Iteritas pitch, attack, morph, harm and spread settings, while the Wogglebug is modulating decay and fold amounts, providing the glitchier drum elements.

Another channel from Pressure Points is routed to CV input 4 on the Ornament & Crime, modulating the Euclidean fill amount on the rhythms that are triggering the BI.

All channels are then routed through the Malekko Mix4, and then through Mutable Warps running Parasite firmware in ping pong delay mode.

Aside from the pitch and gate CV coming from the SQ-1, the 0-Coast is internally patched. The stepped random voltage source is multed, and routed to both the Contour decay length and Slope time. The triangle LFO from the MIDI B CV port (see our 0-Coast Hidden LFOs video) is routed to the Overtone input. Finally the Slope output is routed to the FM input on the Oscillator.
