sfizz vs TX16Wx Software Sampler

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.

TX16Wx Software Sampler is a sampler plug-in for creative musicians, with both disk streaming and RAM playback; disk streaming is included in the free version. It reads WAV, AIFF, Ogg, FLAC, and Yamaha waves, and loads SoundFont, SFZ, Akai, and EXS formats. Editing tools include a sample editor, automatic loop slicing, keyboard mapping, and drag-and-drop group editing. The base feature set includes two resonant filters per voice, modulation envelopes, LFOs, step sequencers, and a modulation matrix. The Professional edition adds pitch shifting, time stretching, send effects, a wave matrix, and group trigger switching. The maker lists VST, VST3, AU, AAX, and CLAP formats, with availability depending on operating system. TX16Wx runs only as a plug-in, not as a standalone app; audio input sampling depends on the host routing audio to it. Listed requirements are Windows 7 SP1 or higher, macOS 10.9 or higher, and Debian Bookworm or equivalent for Linux. Paid access is listed from €39.
