1.5.8
What's New First release on MuseHub — SONATUM has been rebuilt, refactored, and rebranded for this debut. Major Features Multiple Selection & Batch Editing The built-in editor is now significantly more practical. Select multiple elements across the score and edit them together: transpose, rhythmic transformation, deletion, copy/paste operations all work in batch mode. New paste modes (paste into, paste before/after) and a new "clear" deletion mode (remove contents without deleting the container) give you finer control over structural editing. Unified Sub-Panel Editing Pitch and duration can now be altered from the same editor panel—no more switching contexts mid-edit. Playback Improvements Tied notes now play back correctly in all cases. Under the Hood Significant UI Refactoring File browser, Multiline Generator configuration, and editor panels have been rebuilt for clarity and responsiveness. New Documentation Rewritten from scratch to address the actual audience: experienced composers working in contemporary, experimental, and research-driven contexts. More concise, more direct, less tutorial-speak.
Description
SONATUM generates art music using explicit theoretical models (Hindemith, Palestrina, Schoenberg, Persichetti) — no corpus training, no style imitation, no cloud inference. You define structure, density, direction, and constraint; SONATUM renders it immediately, with controlled variation. Made for composers working in experimental, research-driven, or art-music contexts who need to hear whether a process sustains interest, whether tension builds correctly, or whether a textural idea scales — before spending hours writing it out by hand. This is not a finished-piece generator. It's a decision surface: prototype fast, iterate by ear, export when the material proves itself. The score editor is minimal by design; once you're thinking about engraving, you've already moved past what SONATUM is for. If you work with structure, process, and intention rather than improvisation or preset loops, and you value speed in the ideation phase, SONATUM will fit your workflow immediately.
Stochastic Generation Engine: Three configurable generators based on art-music theory—no training, no imitation.
Built-In Score Editor: Minimal notation interface for retouching generated material before export.
Onboard Synthesizer: Audition instantly without leaving the app or rendering externally.
MIDI & ABC Notation Export: Move to your DAW or notation software when the material proves itself.
Template System: Load preset instrumentations with generators already bound and configured.
Time-Evolving Parameters: Multiline Generator supports envelopes for dynamic process control over time.
