I build free, open source music production software by Studio 87, Linux first, with Windows and macOS builds for many: VST3 synthesizer plugins (supersaw, hoover, trance, acid, mono bass and lead, wavetable), effect plugins (compressor, limiter, saturation, distortion, bass enhancer, exciter, spectral sidechain ducker, shimmer reverb, volume shaper), DJ and scratch plugins, an audio editor, a sample manager, analyser plugins, MIDI controller and editor plugins for hardware synths (Korg, Novation, Behringer, Yamaha, Modal) and oscillator and effect units for the Korg minilogue xd and drumlogue. Made with JUCE and C++, as VST3 and standalone apps.

Pre-releases are test builds: they install and run, but are not yet checked on every machine.
