September DAW verification — new work not yet hand-tested

Checks for work landed or in progress since the last VERIFICATION.md pass that no unit test can close. Build Release, install into UserPlugins/, restart REAPER. Panel tail toggle = None, project rate 48000, unless a check says otherwise.

1. Instrument control-surface pass (landed Aug 3, 2026)

• Play notes and watch the ReaSampler 9000 editor's master meter — it redraws smoothly (~60 fps)
• Load a heavy project (several other plugins, high track count) and watch the meter again under that load — still smooth, no visible stutter
• Click the single-button "Envelope" toggle on a deck — cycles on/off cleanly; confirm its disabled-state look when the deck it governs isn't applicable
• Same check for the "Filter" toggle
• Same check for the "Limiter" toggle
• Same check for the "Stage"/"Spline" toggle (the envelope mode selector — one button reading either "Stage" or "Spline")
• Click anywhere on an envelope deck's control section (not just a knob) — that envelope becomes selected for editing on the waveform overlay
• Switch the instrument to Trigger mode — the loop markers and their caption disappear from the waveform entirely
• Switch to Gate mode with looping off — the loop markers still show, greyed out, and are still grabbable
• Zoom in on a loop marker and drag it near a zero crossing — it snaps only within a small pixel radius of the crossing, not from anywhere on the waveform
• Hold Ctrl while dragging a marker near a zero crossing — snapping is disabled for that drag

2. Bank panel additions (Aug 3)

• With a track selected and a bank card focused, click "Insert as FX" — ReaSampler 9000 loads on that track with the focused sample already loaded
• Open the panel's top-toolbar "⋯" overflow menu — Re-capture and Insert Conform are both there and both work
• Drag a bank card over the arrange view — the cursor shows a crosshair cue while over a valid arrange-insert target

3. Design View FX parking (Aug 21)

• Trigger a mode switch that parks/restores FX on a heavy chain, and watch the docked bank panel while the reclaimer drains: the cursor goes busy over the panel and the footer reads "parking FX" / "restoring FX" appropriately. If the cursor never changes, note it — REAPER may not route WM_SETCURSOR to the docked panel at all (src/shell/panel/CLAUDE.md Gotchas)
• Native drag-reorder a parked track's FX chain, switch modes, and confirm each plugin's state restores to the SAME plugin it came from (not swapped by slot)
• Do the same reorder via an SWS move command
• Save the project after a reorder, reopen, then switch modes — restore still keys to the right plugin
• Reorder a chain holding two copies of the same plugin — each copy's state restores to itself, not swapped with its twin (docs/TODO.md §"FX-GUID stability for the park's restore is unverified in the DAW")
• For mode-switching itself (solo-set restore, transport refusal, persistence, undo point count, etc.) — see docs/VERIFICATION.md §"Mode switching"; not repeated here

4. Drag a card into a plugin's editor (landed Sept 2026)

• Drop a bank card on Serum 2's oscillator in its floating FX editor window — Serum loads the sample
• Drop a bank card on Serum 2's oscillator from the FX chain window — same, Serum loads the sample
• Drop a bank card on the FX chain list or window chrome (not the oscillator) — ReaSampler 9000 loads as before, unchanged
• Drop a bank card on the TCP, MCP, or arrange — unchanged from current behavior
• Start a drag over a plugin editor, then move back over the arrange mid-drag — the drag reverts to the panel's own drop behavior (may only visibly update on the next key press or mouse-button change)
• Drag a card out to Windows Explorer and back into REAPER — control hands back to the panel's own drag correctly
• Drop a card onto an already-open ReaSampler 9000 editor — it loads ReaSampler 9000 onto the track (no banner, no OS drop)
• Drop a card onto ReaEQ's editor — shows a no-drop cursor, nothing loads
• Drop a card onto a plugin editor that doesn't accept files (e.g. a compressor) — note whether it is refused (no-drop cursor, nothing loads) or lands in REAPER's own file import; either outcome is accepted, but record which one actually happens
• Run stable and beta ReaSampler 9000 side by side and open both editors — each works normally, no crash

5. Live spline-envelope drags (in progress, Sept 2026)

• Set the amp envelope to Spline, hold a note, and drag a knot — the sound audibly follows the shape change during the drag itself
• Same check for the pitch envelope
• Same check for the filter envelope
• After dragging a knot, trigger a new note — it uses the dragged shape
• Listen closely during a fast drag for any audible glitch beyond what an ordinary knob move would cause (clicks, zippering)
• Drag a knot on a held note and listen for an audible pitch/amp/filter glide as it moves, not a stepped jump
• Release a dragged knot — commits exactly as before: one undo point, and reopening the project keeps the dragged shape
• With a note held, add a new point to the spline — audible immediately
• With a note held, delete a point from the spline — audible immediately

6. Sample-rate playback (in progress, Sept 2026)

• In a 48 kHz project, import a 44.1 kHz file via the Media Explorer into ReaSampler 9000; play its root note — same pitch and length as the file auditioned in the Media Explorer. Repeat in Preserve mode.
• Same with a 96 kHz file in a 44.1 kHz project
• Envelope attack times, loop (a single-cycle loop holds its pitch; loop crossfade length) and filter cutoff sound the same as on a same-rate copy of the file
• Bake a mismatched-rate sample — the baked result has the same pitch and length as what you heard
• Change the project sample rate with ReaSampler 9000 loaded (and with it inactive/bypassed, then re-enabled) — the sample still plays at correct pitch afterwards
• Existing projects that used mismatched-rate samples WILL sound different now (correct pitch) — reopen one and confirm it's the expected change
• Same-rate samples sound exactly as before
