| Fact | Surge XT | Vital |
|---|---|---|
| License | Surge XT source and distributed binaries are released under GPL3, while music and sounds made with it can be commercially used without a separate license. | The public source repository is GPLv3; proprietary use requires a separate license, and source builds cannot use Vital trademarks or its web services. |
| Modulation | Surge XT provides 12 LFO units, DAHDSR envelopes, step sequencing, MSEG modulation up to 128 nodes and Lua-based formula modulation. | Vital supports drag-and-drop modulation, audio-rate modulation, stereo-splittable LFOs, keytracked LFOs and custom envelope curves. |
| Oscillators | Each scene has three oscillators with 12 algorithms including wavetable, FM, string, Twist, noise and audio-input modes. | The oscillators are designed for low noise and near-alias-free output, and unison uses SSE optimizations for CPU efficiency. |
| Plugin formats | Official downloads include VST3, AU, CLAP and Linux LV2 builds depending on platform and release. | The official factsheet lists VST, VST3, AU and LV2 formats. |
| Praise: value | ProSoundPicks described the instrument as fully featured, community-driven and unusually strong value because it is free and open source. | Independent reviews repeatedly describe the full synthesis engine being available free as exceptional value compared with paid wavetable instruments. |
| Self-hosting | The project can be built and installed locally with CMake, including Linux installation under a chosen CMAKE_INSTALL_PREFIX. | The source can be built independently, but the repository says commercial login, downloads and update services cannot be connected from custom builds. |
Surge XT suits music makers and sound designers seeking a synthesizer plugin across Windows, macOS, or Linux. It can also suit developers, designers, testers, and content creators interested in contributing to the project.
Vital suits musicians and sound designers looking for a wavetable synth with extensive modulation and sample-to-wavetable tools. It supports MPE and microtonal tuning, and runs on listed desktop operating systems.
