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
