Exact polyphony and long-sequence path: the mixed WAV starts all voices at the same sample. Import it into Stackadia as a named project sound, then use the existing Script 0.9 play sound command.

Stackadia Music Composer Help

Voices and polyphony

Use up to four monophonic voices. Select a voice tab, then enter and edit its events with the ordinary keyboard and timeline. Each voice receives a distinct Stackadia sound channel derived from the Base Channel and its suffix.

The generated multi-voice handler executes ordinary Script 0.9 play notes commands one after another. They begin very close together, but Script does not provide a sample-accurate simultaneous-start statement. Render Mixed WAV when exact chord alignment is required.

Creating and editing

Arm the red Record control, then use the on-screen keyboard, touch, or the computer keys A through ] to add notes. Disarm Record to audition notes without changing the active voice.

Click one event to edit it. Command-click or Control-click selects separate events; Shift-click selects a range. Duration edits apply to every selected event.

Playback

The transport bar operates the active voice. Ensemble previews use the Voice bar and play a temporary exact mixed rendering.

Timbres

Each voice may use a different preview/WAV timbre. Script 0.9 has no timbre clause, so generated play notes commands remain unchanged.

Compact workspace

Import, output, rendered audio, project settings, examples, and the selected-event editor use collapsible panels to keep the primary keyboard, voice, timeline, transport, and validation tools visible with less scrolling.

Interface themes

Use the Theme selector in the header to switch among Midnight, Paper, High Contrast, and Aurora interface themes. Theme choice is saved in Composer JSON projects.

Project files

Save Project writes Composer JSON format version 4. Versions 1 through 3 migrate automatically. JSON remains distinct from Script and WAV output.
