Firmware for the Kagouyar synthesizer by nozoïd
Kagouyar is a polyphonic, virtual analogue synthesizer designed by nozoïd. It combines simple usage with a huge range of sonic possibilities. Thanks to state-of-the-art technologies, it feels like an analogue synthesizer but includes numerous features and options never seen in a vintage synthesizer.
This repository contains the firmware source code that runs on Daisy Seed by Electrosmith.
- 4 voices of polyphony for creating complex harmonies
- 3 oscillators per voice with atypical waveforms and modulations
- 7 LFOs that can inter-modulate to create complex rhythmic sequences
- Multi-mode filter including a 24dB/Oct low pass
- 2 audio effects (distortion, waveshaper, echo, Doppler effect, etc.)
- Modulation matrix with tactile switches
- 46 control potentiometers
- 16 configuration and assignation tactile switches
- 17 modulation selection tactile switches
- 1-octave tactile keyboard, also used to select specific options
- 27 LEDs to display modulations, selections and options
- No menu: every functionality accessible with only 2 simultaneous touches
- Headphone out (stereo 1/4" jack)
- Audio out (mono - balanced 1/4" jack)
- MIDI IN (5-pin DIN)
- GATE IN (0 to 5V - 1/8" mono jack)
- CV1 IN (Pitch or modulation: -5V to 5V, 1V/Oct - 1/8" mono jack)
- CV2 IN (Modulation: -5V to 5V - 1/8" mono jack)
- Power supply (9-12V DC, 500mA max)
- 2× more VCO waveforms (via long click on waveform)
- 2× more LFO waveforms (via long click on waveform)
- 2× more audio effects (via long click on effect)
- Increased max cutoff of the main VCF
- Added A/D mode (selectable in place of the A/R envelope generator)
- Added DJ mode to the VCF2 filter (low/high on the same potentiometer)
- Added very slow mode for LFO 4, 5 and 6 (up to more than 2.5h period)
- Changed LFO SYNC modulation: frequency division now depends on LFO Fq range, division or multiplication goes from /128 to ×128
- Changed automodulation in LFO SYNC: modulation potentiometer allows dividing or multiplying LFO frequency by factors 1, 2, 3, 4, 8
- New LFO CLIP modulation functionality when no modulation is set: LFO waveform is clipped in various steps (like a bitcrusher)
- When "LOAD" switch is pressed, potentiometers are no longer updated to allow cut transitions
- Added option to use CV switch to control keyboard octave (LOAD + SAVE + KB13)
- MIDI note velocity now controls note amplitude
- Triangle VCO waveform is more expressive
- Added curve to VCF Q for better mapping
- Lots of fine tuning
- Fixed "no sound" bug
To compile this code, you will need:
- A very outdated (and slightly custom) version of libdaisy, provided in the
git_daisy.zipfile - GCC ARM toolchain (arm-none-eabi-gcc)
- Make
