Majik's Music Studio vs Song.do

Majik's Music Studio creates, arranges, separates, and mixes AI-generated music. It uses the open-source ACE-Step 1.5 model and can generate up to five variants at once, with progress shown in real time. Users can upload audio and separate it into vocals, drums, bass, and other parts, with controls for each lane. Mixing tools include track and master-bus EQ, compression, limiting, reverb, saturation, and chorus.

The app exports WAV, FLAC, MP3, and M4A files. Generation can use local or remote ACE-Step GPU servers, including multi-server routing. The maker says processing is user-controlled and runs on the user's machine by default; the app can work offline after setup. It is free, with no subscription required, and supports commercial use. The core Studio app is open source under Apache 2.0. A macOS build and Linux beta are listed; the download page says model weights require an internet connection on first launch and lists 16 GB RAM minimum, with a GPU recommended.
