+## 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 
+
+Using my basic sequencer to drive three tracks. It goes out of sync because
+the basic sequencer has bad timing.
+
+### 4
+
+I implemented a Karplus-Strong algorithm last year, this is two tracks
+of that with different filters applied in the modular.
+
+### 5
+
+Using some very dodgy wavetable synthesis I did last year
+
+### 6
+
+More of the wavetables but this time the aliasing adds to the effect
+
+### 7
+
+Modifying a sequence as it's being played.
+
+### 8 
+
+First experiment with generating clouds of randomised gate signals
+
+### 9
+
+More sequencing and a 7-TET tuning system. The timing errors really show up at
+the end of this
+
+### 10 
+
+Using all four of the DAC's outputs as LFOs to drive a bunch of settings on 
+two tracks of synths
+
+### 11
+
+A beat made with Karplus-Strong through a Doepfler waveshaper and filter and
+echo
+
+### 12
+
+I relearned what I'd forgotten about Arduino interrupts and got a sequencer
+which can count time properly.
+
+### 13
+
+Accidentally made an FM synthesiser by plugging the Karplus-Strong rhythm into
+a VCO's pitch control
