Layers

No layers yet. Add a cover to begin.

Edge threshold 40 Line colour

Foreground / background

Keys out the backdrop by colour: from the edges inward (flood) or everywhere. Use Pick (I) to choose the key colour, or leave it on auto. This is colour keying, not AI; it works best on flat backgrounds.

Record & export

Live, with effects Loop Bounce Format Dither

Record take captures everything you hear. Bounce renders the beat, loops and backing track offline, faster than real time. DSD64 (2.8224 MHz) and DSD128 (5.6448 MHz) are true 1-bit files at the SACD level (−6 dB); they need a DSD-capable player or DAC.

Finishing & space

Console colour, tape, rooms and mastering, rendered offline on exports (WAV and DSD) in 64-bit float. Generic models of classic studio character, not copies of any product.
