A React front end and a FastAPI backend run together from one launcher, so the whole studio starts with a single double-click.
+theDAW packs most of a music career into one program. It writes original audio from a text prompt, arranges it on a multitrack timeline, masters it through a deep effects chain, splits it into stems, performs it across two beatmatched DJ decks, runs a reactive visual show, transcribes it to sheet music and tablature, and files everything in a searchable library that records how each piece descended from the last. It trains custom models on a collection and answers questions about any of it from a built-in assistant. A separate DAW, audio generator, stem separator, DJ rig, VJ engine, notation editor, sample manager, and model trainer collapse into a single window.
-Audio generation happens in the MAKE workspace. A prompt becomes finished audio through Stable Audio 3, and the same model menu also reaches Magenta RealTime 2 for streaming text-to-music and Suno for cloud generation. Chimera fusion can blend several clips into one downbeat-aligned piece, while init signals, inpainting, and LoRA adapters give finer control over the result. When the model selection moves between Stable Audio and the Magenta sidecar, the GPU swap runs on its own.

For live use, the DJ workspace provides a two-deck engine with beatmatch sync, key-lock, live stems, an FX rack, hot cues, and hands-free automix.

A prompt becomes finished stereo, and the same model menu reaches Magenta RealTime 2 for streaming text-to-music and Suno for cloud renders. Chimera fusion folds several clips into one tempo-aligned track, while init signals, inpainting, and LoRA adapters steer a render toward a target.
-Everything generated is kept. The Library stores each piece on disk together with its analysis, stems, and MIDI, and LEARN renders the relationships between pieces as a navigable 3D genealogy. A symbolic-music pipeline produces sheet music, tablature, and multi-instrument arrangements, and it can read a score back into a usable text prompt. LoRA training and autoencoder round-trips have a home in the TRAIN workspace. An in-app assistant answers questions from this guide, and a paste-a-URL importer pulls audio from YouTube, SoundCloud, and Bandcamp.

+A track then moves through EDIT for waveform surgery and region inpainting, and MIX for the Edit Tool Stack and Quick Master macros. The DJ workspace runs two decks with beatmatch sync, key-lock, live stems, an FX rack, hot cues, and hands-free automix, and the VJ workspace drives WebGL visuals from the audio, a microphone, MIDI, or a phone on the same network.

+### 13.9 Suggest a Playlist
+
+The **SUGGEST** button opens a playlist builder that sequences analyzed tracks into a continuous set. The criteria are a target length, an optional BPM range, a flow shape (Steady, Build up, Wind down, or Wave), a harmonic toggle, and an optional genre or text filter. The backend engine (`POST /api/library/suggest-playlist`) reads each track's analysis and orders the set by harmonic key on the Camelot wheel, the chosen BPM flow, and small nudges toward popular and stylistically varied picks, filling the time budget. Each result row shows its BPM, Camelot code, and the reason it was chosen.
+
+Two actions run the result:
+
+- **Play All** loads the sequence into the footer player and auto-advances track to track, restoring the loop preference when it finishes.
+- **Send to DJ** loads the order as the active automix set, switches to the DJ tab, and starts the beatmatch-crossfade automix (see §9.7).

+Suggestions are strongest when the library is analyzed. Unanalyzed tracks still fill the budget but cannot be harmonically sequenced; the analyzer and the analyze-on-add toggle cover this over time.

-theDAW is a complete digital audio workstation built on Stable Audio 3, the state-of-the-art open audio model from Stability AI. The model turns a text prompt into high-fidelity 44.1 kHz stereo audio, and theDAW surrounds that core with a full production environment. A React front end and a FastAPI backend run together from one launcher, so the whole studio starts with a single double-click.
+theDAW packs most of a music career into one program. It writes original audio from a text prompt, arranges it on a multitrack timeline, masters it through a deep effects chain, splits it into stems, performs it across two beatmatched DJ decks, runs a reactive visual show, transcribes it to sheet music and tablature, and files everything in a searchable library that records how each piece descended from the last. It trains custom models on a collection and answers questions about any of it from a built-in assistant. A separate DAW, audio generator, stem separator, DJ rig, VJ engine, notation editor, sample manager, and model trainer collapse into a single window.
-Audio generation happens in the MAKE workspace. A prompt becomes finished audio through Stable Audio 3, and the same model menu also reaches Magenta RealTime 2 for streaming text-to-music and Suno for cloud generation. Chimera fusion can blend several clips into one downbeat-aligned piece, while init signals, inpainting, and LoRA adapters give finer control over the result. When the model selection moves between Stable Audio and the Magenta sidecar, the GPU swap runs on its own.
+
-Editing and mastering come next. The EDIT workspace opens a piece in a waveform editor that supports region inpainting. Effects and loudness work happens in MIX, which hosts the Edit Tool Stack alongside Quick Master macros. For live use, the DJ workspace provides a two-deck engine with beatmatch sync, key-lock, live stems, an FX rack, hot cues, and hands-free automix. WebGL visuals in the VJ workspace respond to the audio and accept MIDI, microphone, and mobile input.

Chimera fusion folds several clips into one tempo-aligned track, while init signals, inpainting, and LoRA adapters steer a render toward a target.
-Everything generated is kept. The Library stores each piece on disk together with its analysis, stems, and MIDI, and LEARN renders the relationships between pieces as a navigable 3D genealogy. A symbolic-music pipeline produces sheet music, tablature, and multi-instrument arrangements, and it can read a score back into a usable text prompt. LoRA training and autoencoder round-trips have a home in the TRAIN workspace. An in-app assistant answers questions from this guide, and a paste-a-URL importer pulls audio from YouTube, SoundCloud, and Bandcamp.

+The **SUGGEST** button opens a playlist builder that sequences analyzed tracks into a continuous set. The criteria are a target length, an optional BPM range, a flow shape (Steady, Build up, Wind down, or Wave), a harmonic toggle, and an optional genre or text filter. The backend engine (`POST /api/library/suggest-playlist`) reads each track's analysis and orders the set by harmonic key on the Camelot wheel, the chosen BPM flow, and small nudges toward popular and stylistically varied picks, filling the time budget. Each result row shows its BPM, Camelot code, and the reason it was chosen.
