- Zoom U-24 iPad USB Audio & MIDI Interface
- Doepfer MSY2 MIDI to analog Clock Converter

Patch Notes:

Four stages of the Sequencer Programmer are addressed randomly by the Gated Comparator, which is driven by White Noise. NCO 1 & 2 and a DUSG in VCO mode are sequenced by the Programmer. Either by the first CV output (the DUSG) or by gates (the two NCOs), which are mixed and attenuated to shift the VCOs a set amount of semi-tones up or down.

NCO 2 also receives pitch CV from the Infinite Melody, going through the Modulo Magic to keep the CV from going too high. The Infinite Melody receives White Noise as well and the Advance input is fed a very fast clock from a second DUSG, which has its speed modulated negatively by the Gated Comparator. This makes the pitch changes from the Infinite Melody not always come in sync with the main clock, creating some interestingly glitchy patterns sometimes.

The three sound sources are mixed and sent through the VCF, modulated by two LFOs and a decay envelope.

The main clock source is the iPad running Kymatica AUM, connected to a Doepfer MSY2 MIDI-to-Analog-Clock converter. The Serge's audio also goes through AUM using the Zoom U-24 Audio & MIDI Interface. Audio effects used are the Kosmonaut delay and AUFX: Space reverb.

Tuning the Serge with all those different mixed pitch CV sources took a bit of fiddling, but luckily the Zoom R16 recorder has a tuner built in, which made it a lot quicker than doing it by ear."
