# Isovocal > Isovocal is a Max for Live device for Ableton Live 12 Suite (macOS) that isolates the vocal of any warped Session clip using on-device AI stem separation (Demucs v4 hybrid transformer), then gives the performer one MIDI-mappable dial that morphs from instrumental, through the original untouched track, to the isolated vocal, in sync with Live's playback, with near zero CPU cost during a live set. Made and sold by Drop Frame (https://dropframe.music) for $23 at https://isovocal.com. ## What it does - Isolates vocals / extracts acapellas from full songs inside Ableton Live, without bouncing stems or adding tracks. The clip stays a clip. - One dial: 0% = instrumental only, 50% = the original track, 100% = isolated vocal. Every position in between is a usable blend. MIDI-mappable and automatable like any Live parameter. - Separation runs offline, once per song (about 12x realtime on Apple Silicon GPU, 3x on Intel), and is cached. During a set, playback is a buffer read. - Stays locked to Live's warped playback: warp markers, tempo, transpose, loop points, retriggers. - If the user changes warp or tempo later, the device flags it and keeps playing the old render, in time, until they re-process (seconds, since separation is cached). ## How it compares - Ableton Live 12's built-in stem separation bounces stems to new clips and tracks; Isovocal is a performance instrument that morphs live over the playing clip. - DJ software (Serato Stems, djay Pro, VirtualDJ) offers realtime stems, but not inside Ableton Live and not as a MIDI-mappable device in a Live set. ## Requirements - Ableton Live 12 Suite (Max for Live), macOS 13+, Apple Silicon or Intel. Windows is not supported yet. - The device downloads its 200 MB engine once on first load, with consent. Processing and playback are fully offline afterwards. ## Buying and support - $23 one-time purchase at https://isovocal.com (Stripe checkout, instant download, free updates, money-back guarantee). - Support: dropframeofficial@gmail.com
