- Plumbed `timeStretchEnvDepth` through `useAudioEngine.ts` down to the `SingingVoice` and `rubberband-processor.ts`. - Added grouped UI sliders for `timeStretchEnvDepth`, `spectralPanRate`, and `spectralPanDepth` to `NoteSelector.tsx`. - Mapped per-step properties through `ContextMenuNode.tsx`. - Added global Knobs for Spectral Pan Rate and Depth to `SamplerPanel.tsx`. - Updated test parameters to fix component count assertions. - Updated `agent_plan.md` to reflect completed tasks and added new roadmap ideas.

- Fix a bug in `RbsImporter.ts` where `slideTime` was referenced instead of the unnormalized `rawSlideTime` when defining the Bass2Params parameter mappings, causing a ReferenceError during CI tests. Co-authored-by: ford442 <9397845+ford442@users.noreply.github.com>
- Resolved `slideTime` ReferenceError in RbsImporter by substituting `portamento` where `slideTime` was out of scope. - Fixed a duplicated `currentStepRef` object literal property in useAppState.tsx. - Added missing `length` property to Voice.test.ts SynthParams mock. - Addressed `Float32Array` type mismatch with `ArrayBufferLike` in `useLevelMeter.ts`. - Removed an unused `@ts-expect-error` in `RustOscillator.ts`. - Removed an errant comma causing unused-expression error in `patternRandomizer.test.ts`.

In `@public/jc303-threaded.js`:
- Line 1: The expression for ENVIRONMENT_IS_PTHREAD accidentally runs into the
following IIFE, causing the string "em-pthread" to be invoked as a function; fix
by separating the boolean expression from the IIFE — change the sequence around
ENVIRONMENT_IS_PTHREAD and the immediate (function(){...})(); so
ENVIRONMENT_IS_PTHREAD is assigned the boolean (e.g. keep var
ENVIRONMENT_IS_PTHREAD=!!globalThis.WorkerGlobalScope&&globalThis.name=="em-pthread";)
and then run the wasmTable init IIFE as a standalone statement
(function(){...})(); so locate the ENVIRONMENT_IS_PTHREAD definition and the
following wasmTable initialization IIFE and insert the separator (semicolon) or
end the assignment before the IIFE.
In `@src/components/RbsImportModal.tsx`:
- Line 409: RbsImportModal currently doesn't trap or set focus when opened;
update the modal to use the existing useFocusTrap hook: add a ref (e.g.,
modalRef) to the dialog container (ensure it has tabIndex={-1} so it can receive
focus) and call useFocusTrap(modalRef, { initialFocus: closeButtonRef }) where
closeButtonRef points to the modal's close button or first interactive control;
ensure the close button/getInitial focus ref is created (useRef) and passed as
initialFocus, and confirm focus is restored on unmount/close by relying on the
hook's restore behavior or calling focus on the previously active element in the
modal close handler in RbsImportModal.
In `@src/hooks/useAppState.tsx`:
- Around line 1181-1185: The code nullifies subsequent steps using a hardcoded
256 bound which can overflow the actual lane length; update both loops that
check targetIndex < 256 to use the actual step-array length (e.g., targetIndex <
newBank.steps.length or the lane size constant) so nullification stays inside
the lane; locate the loops that reference newBank.steps, stepIndex and newLength
(the blocks around the current nullification and the similar block at the other
occurrence) and replace the 256 check with the dynamic length check.
In `@src/hooks/useAppState.tsx.orig`:
- Around line 1-1258: Remove the merge-conflict backup file
(useAppState.tsx.orig) from the PR and prevent future commits of .orig files:
delete the .orig file from the changeset (so only the correct useAppState.tsx
remains), add the pattern *.orig to .gitignore, stage the .gitignore update, and
commit/push the changes; verify the exported symbol/useAppState hook
implementation is coming from useAppState.tsx (not the .orig) before merging.

Fix focus management for RbsImportModal when it opens
RbsImportModal renders a proper dialog (role="dialog", aria-modal="true", aria-labelledby/aria-describedby) and handles Escape, but it does not appear to manage focus for keyboard users:
- The dialog container has no
tabIndexinsrc/components/RbsImportModal.tsx(line ~409) and the component has no focus calls. - The modal only registers a keydown handler for Escape (no Tab trapping).
- The codebase already has a
useFocusTraphook (src/hooks/useFocusTrap.ts) used by other modals (e.g.,VoiceEditor,NoteSelector,PatternSelector), butRbsImportModaldoesn’t use it.
Please update RbsImportModal to use useFocusTrap (and set an initial focus target such as the close button / first interactive control) to ensure focus moves into the modal, Tabs can’t leave it, and focus is restored on close.

Use step-array bounds instead of hardcoded 256 during note-length nullification.
Line 1183 and Line 1206 use targetIndex < 256; this can extend steps past the lane size and produce inconsistent pattern arrays.
Suggested fix
for (let i = 1; i < newLength; i++) {
const targetIndex = stepIndex + i;
- if (targetIndex < 256) {
+ if (targetIndex < newBank.steps.length) {
newBank.steps[targetIndex] = null;

Remove merge conflict backup file from the repository.
The .orig extension indicates this is a backup file automatically generated by merge tools (e.g., git merge, git stash) during conflict resolution. These development artifacts should not be committed to the repository.
Recommended actions:
- Delete this file from the PR
- Add
*.origto.gitignoreto prevent future accidental commits
git rm src/hooks/useAppState.tsx.orig
echo "*.orig" >> .gitignore🤖 Prompt for AI Agents
Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.
In `@src/hooks/useAppState.tsx.orig` around lines 1 - 1258, Remove the
merge-conflict backup file (useAppState.tsx.orig) from the PR and prevent future
commits of .orig files: delete the .orig file from the changeset (so only the
correct useAppState.tsx remains), add the pattern *.orig to .gitignore, stage
the .gitignore update, and commit/push the changes; verify the exported
symbol/useAppState hook implementation is coming from useAppState.tsx (not the
.orig) before merging.

Implemented UI controls for the 'Time-Stretch Envelope' and 'Spectral Panning' features and connected them to the underlying audio engine. Added comprehensive per-step overrides in NoteSelector.tsx (styled consistently with the app's advanced parameter groups) and global track adjustments in SamplerPanel.tsx. Test suites updated and fully passing.
