Drum hits, one-shots, a few loops. Open in any DAW.Synth XR takes one one-shot — a kick, a bass note, a pluck — and a target key, and generates 30 variants in that key. The engine is a perturbation-style DDSP synth (RAVE 2.4 in the background, controlled by a small parameter head we train per kit family).

Synth XR takes one one-shot — a kick, a bass note, a pluck — and a target key, and generates 30 variants in that key. The engine is a perturbation-style DDSP synth (RAVE 2.4 in the background, controlled by a small parameter head we train per kit family). You drop a sample into the well, pick C minor or F#, and a 6 x 5 grid of variants renders in 0.4 s on an M2. Each variant is itself a playable instrument — full MIDI range, sample-accurate, with the same envelope and velocity rules as the source. You commit one to a preset and the patch is named after the source file. The model is good at percussive one-shots and short tonal samples; for sustained pads longer than 6 seconds the underlying RAVE quality drops and the standalone Output Arcade still wins.
Dated, terse, one fact per line. No 'general improvements'.

Synth XR is tested in Cubase, Logic Pro, Ableton Live, Studio One, Bitwig, FL Studio, REAPER as CLAP, VST3, and AU. The build is code-signed with Apple Notarytool on macOS and EV-signed on Windows (DigiCert).
No. Activation runs once over the internet, then the plugin runs offline. Two activations per license.
The model file is fetched from the SONICHAOS lab CDN and hot-swapped without a plugin reinstall. You can pin a version in Preferences if a session needs to stay bit-stable.
No. Generation runs locally over ONNX Runtime. The lab is only contacted to fetch a base model the first time you pick a kit family.
Each variant is a playable instrument — the full MIDI range, sustained for as long as you hold the key. Generation cost is fixed per variant, regardless of held duration.
Honest scope: pads longer than 6 seconds drop in quality. For long pads the standalone Output Arcade still wins.
