# 0006 — Bounded MIDI notes and internal instrument
|
|
|
|
Status: accepted, Phase 7.
|
|
|
|
Use the existing JACK backend for timestamped MIDI input, avoiding another
|
|
backend/dependency. Store source-relative notes in the C project and v3 format;
|
|
read v1/v2 without MIDI. Prepare sample spans on the control thread and render
|
|
a small sine instrument into its own graph source buffer. Use a piano roll to
|
|
meet draw/play/save/reopen acceptance before adding MIDI capture or SMF import.
|
|
|
|
Keep explicit bounds: 4096 project notes, 32 overlapping scheduled notes, 32 live
|
|
voices and 256 events/block. Reject scheduled overcapacity at preparation; steal
|
|
oldest live voices. Panic handles event loss, disconnects and callback failures;
|
|
Stop/seek resets live state. Immediate note-off and a fixed sine voice keep this
|
|
prototype small, at the cost of possible clicks and no expressive controllers.
|
|
See ../MIDI.md for ownership, detailed limits and validation.
