Layers original stems and your voice
Stems from a loaded song appear here (drums, bass, vocals, other). Mute any to replace it with your own or the AI's. Record voice adds a take over the beat. All layers play with the transport and are included when you download audio.
Sounds
Voices are synthesised by default. Load a kit or sampled instruments for realism, or drop your own one-shot on a drum voice.
▸ Add your own sounds upload a bought pack (.zip) or a folder
Pick a folder of one-shots. Files named after the drum they play (kick, snare, hat, clap, ride, tom, perc) become a kit. Files with note names in them (C3, F#2) become a playable instrument. Once built, the AI can choose it by name like any other pack.
