Vaporizer 2
What it is
Vaporizer 2 is a free, open-source synthesizer and sampler workstation for Linux, macOS, and Windows. It combines wavetable, additive, FM, and subtractive synthesis with sample playback and granular synthesis. Its four wavetable oscillator banks support up to 24-oscillator unison, and its editor can draw wavetables with Bezier curves, edit cycles, and import Serum- and Icarus-format wavetables. The sampler accepts WAV, AIFF, OGG, and MP3 files, with loop points, key tracking, and sample-to-wavetable resampling. The product page lists more than 780 wavetables and single cycles and more than 410 factory presets. Modulation offers 25 sources and 220 destinations, with five MSEG envelopes and five LFOs. It supports MIDI Polyphonic Expression and is available as plugins and a standalone app. Listed plugin formats include VST2, VST3, AU, AAX, CLAP, and LV2. The maker describes a lifelong free update policy. The README specifies at least 1 GB RAM and a CPU supporting AVX or SSE2.
