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
