Patch Notes #20 - Electronic Drum Pads w/ 0-Coast & DU-SEQ


Published on Sep 22, 2016 Voltage Control Lab

"Putting this 16 year old homemade electronic drum pad to work with the DU-SEQ, the Make Noise 0-Coast and the rest of the eurorack system to generate some weird stuff for Patch Notes #20.

The DIY electronic drum pad is patched via RCA to 1/8" cable to the tempo in on the 0-Coast. The clock out is patched to the clock in on the DU-SEQ, which has it's pitch and gate patched back to the 0-Coast. In this configuration, the drum pad is clocking the 0-Coast and the DU-SEQ. The stepped random out on the 0-Coast is multed to the overtone CV input and the slope section time control. The multiply section is modulated by channel 2 on the Ornament & Crime in quadraturia mode. The slope output is routed back the FM input on the oscillator.

The 0-Coast is routed out through the Vintage Synth Lab VCF-74 with boost enabled for some warmth, then on the the Mutable Instruments Warps ping pong delay in the Parasites firmware, which is modulating the delay time with the internal LFO, and then out to the Malekko Mix 4.

The DU-SEQ is in CV address mode which acts like a sample & hold circuit, more on this in a coming video. The stage address is being modulated by a cycling channel on Maths. Maths' both input is in turn being modulated by one of the fluctuating random voltage outputs on the Sputnik Modular West Coast Random Source. One channel on the Malekko Varigate 4 is randomly gating the Ext gate input 1 on the DU-SEQ as well, which is assigned to one of the 8 steps in the sequence. Any time the step is played, the random gate sequence coming from the Varigate is heard until the sequence steps to another note.

The Korg SQ-1 is playing back the bass part on the Noise Engineering Basimilus Iteritas, with the morph control modulated by another channel on the Ornament & Crime. The output is routed to the Mix 4.

Braids is droning around, with the pitch modulated by the Make Noise Wogglebug, and the timbre and color modulated by the leftover 2 LFOs on the Ornament & Crime. The output is multed through a buffered mult, and then routed to an input on the Sputnik Modular 4tap Delay as well as one of the crossfader inputs on the 4tap (so we can mix the clean and delayed signals). One of the 1/3 outputs on the delay is routed to the other input on the crossfader, with the second output sent to the Malekko Dual Borg filter in high pass mode, then back to another input on the delay creating a filtered feedback loop. The filter cutoff is being modulated by the cycling Malekko Envelator, while the West Coast Random Source fluctuating random voltage is modulating the delay time. Out from the delay to the Mix 4 with the rest and out.

Warning: Tweaking your modular should be done without drumsticks in hand.
