A basic additive synthesiser in C++ with accompanying DSP library.
Using olcPixelGameEngine, olcPGEX_Sound (modified), Dear ImGui and olcPGE Dear ImGui backend implementation.
MIDI support now included with RtMidi.
All dependencies are included directly or as git submodules. To clone all required files
simply use the --recurse-submodules flag when cloning this repository:
git clone --recurse-submodules https://github.com/nospi/synth2
The project is built with Visual Studio 2019 - no alternative build scripts are attached but I'd be open to pull requests for additional environments.
- 3 oscillators
- 4 wave functions (Sine, Square, Sawtooth, Triangle)
- 2 resonant filters
- ADSR envelope (applies to all 3 oscillators)
- Compressor
- Limiter
- 4 unit FX rack (currently running as inserts with a dry/wet mix)
- Realtime waveform and FFT visualizers
- Custom presets
- QWERTY or MIDI keyboard input
- Configurable UI
- Keyboard visualizer
- Velocity sensitivity
- (Some) parameter smoothing
- Mono Delay
- Concurrent multi-channel support
- Efficient wave function approximations
- LFO
- Wave functions:
- Noise
- PWM
- Algorithmic Reverb(s)
- Overdrive
- Fuzz
- Flanger
- Phaser
- Chorus
- Ping Pong Delay
For convenience, all dependencies are included as submodules under $(SolutionDir)/libs. To include these use the --recurse-submodules flag when cloning this repository.

Modify FX from insert routing to send routing.

Ideally the fx unit will be configurable between insert and send.
- Filters should be configurable as pre/post dynamics; and pre/post FX
- FX units should be configurable as pre/post dynamics
