ZynAddSubFX is a fully featured open source software synthesizer with three synthesis engines (additive, subtractive, and PAD) capable of producing a vast range of instrument sounds. It runs standalone or as a VST/LV2 plugin across Linux, Windows, and macOS with extensive MIDI and audio driver support.

Use cases

• create synthesizer instrument sounds for music production
• generate pads and ambient textures with pad synthesis
• make microtonal music with custom scales
• use a software synth as a VST or LV2 plugin in a DAW
• play a virtual keyboard without a MIDI controller
• layer multiple instruments into kits for drum or layered sounds

When to choose

• you need a free, powerful polyphonic software synthesizer on Linux, Windows, or macOS
• you want multiple synthesis engines (additive, subtractive, PAD) in one tool
• you need microtonal scales and flexible MIDI/audio driver support like JACK or ALSA
• you want a synth that works standalone or as a VST/LV2 plugin

When to avoid

• you need a simple, lightweight synth with minimal CPU usage
• you require a fully open-source UI without any paid binary components
• you want sample-based or wavetable synthesis rather than synthesis engines
• you need a mobile or web-based synthesizer
