Arduino Synth Build for Generative Techno, using Mozzi library in Volca-form-factor.

My first Arduino project started as an experiment in what noises I could make, and turned into a cool little generative synth that I can let run all day, built to fit in with my Volca collection.

Inspired by Hagiwo's modular builds: https://www.youtube.com/channel/UCxErrnnVNEAAXPZvQFwobQw

Synth Voice Features
- 2 saw oscillators
- Multiple tuning modes for 2nd oscillator - off, detune, fifths & octaves up/down
- Digital low pass filter with variable cutoff and resonance - Variable level ducking/sidechain effect

Sequencer Features
- Generative sequencer mutates/evolves at user-defined rate
- Sync input & output (Korg Volca compatible)
- Variable sequence mutation probability & note-density
- Variable sequencer length (1-16 steps)
- Selectable tonic note
- Selectable scale quantisation (Major, Minor, Pentatonic, Phrygian (GOA!), Octaves, Fifths)
- 16-step parameter-lock recording of synth parameters (the Elektron way!) - Retrig (clone) button for fills
- Tap-tempo control

Hardware
- Arduino Nano (Elegoo)
- Simple Mozzi output circuit
- CV inputs (volca modular levels) for synth and sequencer parameters
- Designed to fit into Volca form factor
- Laser-cut metalisized acrylic faceplate
- Laser-cut wooden box
- 9V DC Power input
- Access to nano's USB port for firmware upgrades

Problems (mostly electronic hardware due to this being my first project!)
- no voltage protection on inputs
- no buffering of inputs or outputs
- no volume control
- probably more unknown unknowns 😂
