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](https://music.mikelynch.org/library/albums/31/)
## Track notes
### 1 Logistic
Using the [logistic map](https://en.wikipedia.org/wiki/Logistic_map) at an almost-chaotic point to control pitch
### 2 300 Baudrillard
The noise is the output from the logistic map 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 the [Karplus-Strong algorithm](https://mikelynch.org/2024/Feb/03/buffer/) early this 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 earlier this 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 waveshaper module 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
### 20 Fibomod
Using the Fibonacci series modulo n, also known as the (Pisano period)[https://en.wikipedia.org/wiki/Pisano_period], as a wavetable, and incrementing n for each note in the sequence
### 21 Jacob's Ladder
Deliberate FM synthesis by using a wavetable as the control voltage of a VCO
### 22 Onomatopoeia
Triggering LFO patterns from the sequencer
### 23 Ha Ha
Using the triggering stuff from 22 to build a track with more structure
### 24 Wander
Another 7TET piece using the sequencer
### 25 Ribosome
Using the sequencer to trigger envelopes and LFOs at two scales - notes and
bars
### 26
Basic slew / portamento
