Stems 1.0.0

Stems 1.0.0

First release.

Download Stems.zip, unzip, move Stems.app to Applications. Signed and notarized, opens like any Mac app. The first separation downloads the Demucs model (about 80 MB), then everything runs offline on the GPU.

• Mixer with per-stem mute, solo and volume, all stems sample-locked
• Tempo 50 to 150 percent and key shift up to an octave, live
• One-click karaoke and acapella, export any mix or all stems as 24-bit WAV

Requirements

macOS 14 or newer on Apple silicon.
