CAmenti

November 9, 2018

Record and slice a sample into segments and play those segments in a rhythmic pattern from a generative algorithm called Cellular Automata (CA).

Instructions

The CA is made up of 256 rules and selecting a different rule will play the segments in a different pattern. Set master in/out points in your root sample. Stitch segments together to form sustained (uninterrupted) sounds. Turn segments on and off with the keyboard keys. Sample drums and make a new rhythm! Sample sustained sounds to make a choppy bounce!

CA Additive

Cellular Automata

The very graphic Elementary Cellular Automata generative algorithm individually controls 15 partials of an additive synthesizer. Create looping and evolving synth voices.

Instructions

Elementary Cellular Automata (CA) is a generative algorithm with 255* ‘rules’ that create graphic patterns. These patterns are shown on the Organelle's OLED screen as white or black boxes. A row represents a single generation. The columns represent 15 audio partials. Partials are individually turned on or off each generation. Active partials are shown using white boxes; inactive ones are black. The CA generates along the y-axis from top to bottom and have a selectable loop length (number of generations before starting over) and tempo (generation speed). Select from 13 waveforms.

The patch is Link enabled so the CA generation will sync/share tempo with use of compliant WiFi adapter.

Knob3: CA Loop Length

Knob4: Synth Waveform

Aux: Latch/Sequencer Control

Foot Switch: Stops CA Generation

* Really there are 256 rules but the first rule doesn't generate a useful control the way we implemented CA in this patch. We decided to ignore that rule: Sorry Rule 0!

CA Filter

Cellular Automata

CA Filter is a 15-band filter controlled by a generative algorithm called Elementary Cellular Automata.

Instructions

Send the patch an audio signal and as the Elementary Cellular Automata (CA) generates, the 15 audio bands are individually turned on or off, dynamically filtering your sound. The CA has 256 ‘rules’ that create graphic patterns which are shown on the Organelle screen. 15 boxes along the X-axis represent the 15 frequency bands (left to right = low to high frequencies). Active audio bands are shown using white boxes; inactive bands are black.

The CA generates along the y-axis from top to bottom and have a selectable loop length (number of generations before starting over). If the CA is generating, the keys are disabled. If the CA is paused, the first 15 keys toggle the frequency bands on/off.

The patch is Link enabled so the CA generation will sync/share tempo with use of compliant WiFi adapter.
