sfizz vs Vaporizer 2

sfizz is a sample-based musical synthesizer built around the SFZ instrument format. It can load existing SFZ libraries or support the creation of personal instruments. The software supports SFZv1 and has partial compatibility with SFZv2, so some features of the newer format may not work fully. sfizz is available as VST3i, Audio Unit and LV2 plugins, as well as a standalone JACK client. Instrument makers can use hot reload to revise custom instruments and check changes without manually operating the software. Its streaming system loads sounds when needed and reclaims memory once sounds are no longer in use. Developers can integrate the engine into other programs with C and C++ API bindings; it accepts an SFZ file and MIDI-type events and renders audio through successive callbacks. Downloads include Linux packages, Windows 32-bit and 64-bit installers, and a universal macOS package for Intel and Apple Silicon. The project requires no payment to use, with optional donations. Its repository was archived on June 21, 2026 and is read-only.

Vaporizer 2 is a free, open-source synthesizer and sampler workstation for Linux, macOS, and Windows. It brings together wavetable, additive, FM, subtractive, and sample-based sound generation, with a granular mode. Four alias-free wavetable oscillator banks support up to 24-oscillator unison. The editor can draw wavetables with Bezier curves, edit cycles, and import Serum- and Icarus-format files. Sampling supports WAV, AIFF, OGG, and MP3, as well as 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, 220 destinations, five MSEG envelopes, and five LFOs; MIDI Polyphonic Expression is supported. It is available as a standalone app and in plugin formats including VST2, VST3, AU, AAX, CLAP, and LV2. The README specifies at least 1 GB RAM and a CPU supporting AVX or SSE2. The maker lists lifelong free updates.
