Looptober 2024

This year for Looptober I decided to use my Arduino (in combination with my modular synth rack) for every track. The source code for each day's track is here and the tracks are on my Funkwhale server

Track notes

1 Logistic

Using the logistic equation at an almost-chaotic point to control pitch

2 300 Baudrillard

The noise is the logistic equation as an audio-rate signal, sequencer is also the Arduino

3 Spoopy

Using my basic sequencer to drive three tracks. It goes out of sync because the basic sequencer has bad timing.

4 Strong Fish's Fight Theme

I implemented a Karplus-Strong algorithm last year, this is two tracks of that with different filters applied in the modular.

5 Bad Wavetable

Using some very dodgy wavetable synthesis I did last year

6 Cyber Jubilee

More of the wavetables but this time the aliasing adds to the effect

7 Mutations

Modifying a sequence as it's being played.

8 Cellophane

First experiment with generating clouds of randomised gate signals

9 Stomp 7

More sequencing and a 7-TET tuning system. The timing errors really show up at the end of this

10 Too Many LFOs

Using all four of the DAC's outputs as LFOs to drive a bunch of settings on two tracks of synths

11 Scratchpad

A beat made with Karplus-Strong through a Doepfler waveshaper and filter and echo

12 Interrupt

I relearned what I'd forgotten about Arduino interrupts and got a sequencer which can count time properly.

13 Accidental FM

Accidentally made an FM synthesiser by plugging the Karplus-Strong rhythm into a VCO's pitch control

14 Mondayitis

Trying to make something moody with the sequencer

15 Stretch

Trying to make something a bit funky with Karplus-Strong but that accidental FM synth is crawling around in the background

16 Eggmeat for Rooroo

The accidental FM synthesiser being tweaked in two channels

17 Superheterodyne

Fiddling with sliders on one of my synth modules resulted in this scratchy stuff

18 At Anchor

A better (I think) attempt at making something moody with the sequencer

19 Craquelure

Using the random-note-clouds technique from the 8th but this time picking pitches from a hexany tuning, running it four times and drenching it in reverb
