Pymss vs Suno

Pymss is an open-source music source-separation toolchain that runs on the user's own machine and separates audio into vocals, drums, bass, and other stems. Its Studio desktop workspace handles model management, batch jobs, and stem editing. Users can import files or folders, choose a downloaded model, configure inference, and queue work. Studio can browse, download, resume, and delete model files, with storage cleanup controls. Waveform previews, mix controls, saved projects, and stem export support work on the results. Pymss can chain models so each workflow step uses the preceding step's output. The inference package lists WAV, FLAC, MP3, M4A, AAC, Opus, Vorbis, and Ogg output. Other components include ComfyUI custom nodes, a VST3 ARA plugin for compatible DAWs, and a browser interface bundled with the server. The ARA plugin provides per-stem mute and solo controls; its README gives Reaper and Studio One as host examples. The repositories have separate licenses: Studio is listed under AGPL-3.0 and the inference package under MIT. Studio remains at an early development stage, and changes between versions may break things.

Suno creates complete songs from text prompts in under a minute. It supports vocal generation, audio uploads, multitrack editing, MIDI sequencing and stem export, with audio export in MP3 and WAV. Tracks can be up to eight minutes long. Users can share music with audiences ranging from a small circle to millions. The Free plan costs nothing and provides 50 credits per day, allowing up to 10 songs daily without a credit card; it does not include commercial rights or monthly song downloads. Free uploads can be up to eight minutes. Pro costs $8 a month and provides 2,500 credits and 20 song downloads per month. Premier costs $24 a month and includes 10,000 credits and 60 downloads. Paid subscribers can use songs commercially, including in videos, albums and other projects. Annual billing gives a 20% discount on both paid plans. Pro and Premier let users create custom models from recordings; Premier adds Suno Studio with MIDI, effects and automation. Suno is available on the web and on Android and iOS.
