About the synth
A small canvas.
A wider palette.
Created by J. Baudru (Bonoob). Made by Bonaub.
Sympl brings three independent oscillators into one focused instrument. Blend sine, square, saw, triangle and noise, then shape each layer with its own envelope, filters, tuning and stereo pan.
Play chords with 16-voice polyphony or switch to monophonic legato glide for sliding basses and leads. Save your discoveries as presets, recall them in your DAW, or roll the dice to find a new starting point.
From a waveform to a world
Shape. Move. Finish.
Three clear views. One connected instrument.
Every layer has its place.
Make it breathe.
Route three LFOs through a readable modulation matrix. Add filter movement, shifting pan or changing envelopes, with free-running rates or DAW-synced divisions.
Give it a space.
Add distortion, chorus, delay and reverb. Drag the effects into your preferred order, dial in the mix, and sync chorus and delay to your session.

Which systems does Sympl support?
Sympl is Windows only: Windows 10 or 11, 64-bit. The plugin uses the VST3 format, so your DAW must support 64-bit VST3 instruments. There is no macOS, Linux or Audio Unit release.
Can I use it without a DAW?

How do I install the plugin?
Run the Windows installer and choose the VST3 location your DAW scans. The default is C:\Program Files\Common Files\VST3. Restart or rescan plugins, then add Sympl to an instrument track. The default shared installation requires administrator permission.

A lot of factory presets give you a starting point. Save your own patches with the built-in preset manager.
