Patch Notes #8 - Korg SQ-1 Eurorack Modulations

Published on Jul 24, 2016 Voltage Control Lab

"Episode #8 of Patch Notes explores the Korg SQ-1 as a Eurorack modulation source, controlling the pitch of the bass on one channel, and wobble rate on the other.

Tempi is clocking SQ1, which has an 8 step sequence with a 2 volt range on Channel A controlling the wobble rate on the Slope section of the 0-Coast. A 4 step sequence on Channel B is controlling the pitch of the 0-Coast Oscillator, which is playing the bass part.

Tempi is also clocking the René, the QCV output of which is controlling the pitch on Braids, while the fluctuating random out from the Wogglebug modulates the FM input in Meta mode, scrubbing through the wave programs. The stepped random output on the 0-Coast is multed and routed to both the Timbre and Color controls on the Braids.

Braids is routed through Ripples VCA output, which is being triggered via Maths Channel 4. The Fall time is modulated by the CV output from René. Channel 1 is cycling in a long triangle shape, and output to the 1v/oct input on the TipTop Audio Z3000. The sine output is routed to the Ripples FM input.

Tempi is also clocking Brains and Pressure Points, modulating the Basimilus Iteritas Decay, retriggering the cycling Slope section of the 0-Coast, and sending 2 rows of PP through the Doepfer 151-2 Sequential Switch. From the 151-2, the sequence is sent on to the Ornament and Crime CV 4 input, which is modulating the channel D Euclidean Fill amount in Piqued mode (also clocked by Tempi).

Ornament and Crime is then routed out to the Envelator, which is modulating both filters on the Dual Borg, to produce the kick drum.

The Sputnik Oscillator and Malekko Anti-Oscillator are generating LFOs and cross-modulating each other, each then routed to modulate the PItch, Morph, Fold, and Spread on the BI.

Trigger sequences for Braids and the BI are coming from the Varigate 4, each with heavily randomized note probability and repeats. All channels are then routed through the Mix4 and on to Warps for some delay magic.
