Pure browser_scroll/note_entry/param_slider modules (+ CTest) for scroll, type-to-filter search, numeric note entry, and the AHDSR/Trigger/pitch-engine/ pitch-env control panel. Editor shell draws + routes through them; params edit the selected zone's ZonePlayParams via commitAndReload.

// note_entry.h — PURE parse + clamp for the S12 direct numeric entry of a zone's
|
|
// low/high/root MIDI note. NO VST3, NO REAPER, NO SWELL/LICE types at the boundary. The
|
|
// mirror of the other pure editor helpers: the fiddly text->note parse lives here, unit-
|
|
// tested outside the DAW, while the editor shell hosts the text field (a SWELL edit control
|
|
// or a LICE text-entry idiom) and feeds the committed string here on Enter.
|
|
//
|
|
// WHY IT EXISTS (S12). Low/high/root are draggable on the keyboard strip, but a drag can't
|
|
// hit a precise note reliably. This adds a typed field: the user clicks the field, types a
|
|
// value, and presses Enter; the shell hands the raw string here to parse into a clamped MIDI
|
|
// note [0,127] and commits via the same off-thread reload as every other edit.
|
|
//
|
|
// ACCEPTED FORMS (both, so a musician OR a MIDI-number user is served):
|
|
// * a plain decimal integer ("60", " 127 ", "+5") — the raw MIDI note number; and
|
|
// * a note name ("C4", "f#3", "Bb-1") — parsed to its MIDI number under the DAW's C4==60
|
|
// convention (MIDI 0 == C-1, matching REAPER + the editor's noteLabel).
|
|
// A value out of [0,127] CLAMPS to the range (a typed 200 becomes 127) rather than
|
|
// rejecting — the least-surprising behavior for a nudge field. Unparseable input returns
|
|
// nullopt (the shell keeps the old value + may flash the field).
