I've finally spent more time with the Axoloti again and started several projects. This one is the first that got finished: the "Conduttrice" LED sequencer and drum synthesizer!
The idea came to me when playing with the Lumanoise synthesizers, which use light (LDRs) to change pitch and filter cutoff frequency. I wanted a box that can output light synced to a beat, for example from the Multicassa analog drum machine, by the same manufacturer. The Axoloti was perfect for this!
Features of the "Conduttrice":
- 2x analog clock inputs (or internal clock)
- 3x clock dividers with pulse width control, driving LEDs (digital out)
- 2x LFOs (with Sine, Ramp & Square waves) driving two LEDs (pwm out)
- Drum synth using the clock divider triggers to ping low-pass filters, modulated by the LFOs
- 5x 9V center-positive plugs to power the Axoloti and also four other 9V devices with one power supply (like the three Lumanoise synths and Multicassa drum machine I'm using)
- Axoloti USB port can be used to attach other USB light sources, like LED strips for added luminous craziness
I attached the LEDs using 3.5mm cables and I'm waiting for a delivery of proper gooseneck thingies so that the LEDs don't just loosely hang there.
Here's a short video of everything in action:
