@ -55,3 +55,47 @@ and workflow tests cover the retained commands. A modern presentation does not
add commercial-DAW features: detachable/resizable docks, mixer channel strips,
automatic plugin scanning, custom plugin editors and new audio/MIDI features
remain outside this phase. Existing plugin and engine limits still apply.
## Phase 34 editing controls
The **Snap** dropdown above the sequencer selects Off, 1/32, 1/16 triplet,
1/16, 1/8 triplet, 1/8, 1/4, 1/2 or one bar. Existing View/Snap commands update
the same preference. Bar lines are strongest, beats medium, subdivisions subtle.
At low zoom closely spaced lines are coarsened to at least six pixels; snapping
still uses the selected division. Clip moves and trim boundaries snap to the
nearest absolute grid position (halfway rounds forward), including clips that
start off the grid. Off removes musical quantization; pointer resolution and
integer model ticks still apply. Invalid trims retain the original clip.
Snap is a UI preference, not a project edit or a saved project setting.
Double-click a MIDI clip with the left mouse button to open its piano roll.
The clip is selected and the click does not move/trim it. Audio/silent clips
retain their existing selection/drag behavior. The piano roll also has a Snap
dropdown for its existing note grid; sequencer and piano snap remain independent.
The piano roll has a fixed **Velocity** lane beneath the keys and a **Note
velocity** slider. Select a note, then drag its bar vertically or release the
slider at a value from 1 to 127. Only that note changes; pitch, timing, length,
channel and other notes stay intact. One completed drag/slider edit is one undo
step; Escape cancels a lane drag. For chord notes sharing a start time, select
the desired note in the keys first; its highlighted velocity bar and slider
remain individually editable. Horizontal scrolling aligns the lane with note
starts; vertical scrolling moves the keys while the lane stays available.
Filters apply to lane visibility and selection. Values save with existing note
metadata and affect built-in synthesis; plugin patches determine velocity response.
This is MIDI velocity, not a per-note audio gain or loudness meter.
Every ordinary track header has an instrument dropdown. Choose **Built-in sine**,
an instrument already assigned elsewhere in the project, or **Load plugin...**
for a trusted CLAP/VST2/VST3 binary. Entries show the format and plugin label.
Each assignment creates an independent track instance, selects that track for
live MIDI and remains undoable; clear/reorder/reopen use stable track IDs. Bus
tracks show their bus label instead. Cancel or failed preparation restores the
model's selection in the dropdown. The list is project-local, not a scanner or
installed-plugin database. Existing mono/default-configuration host limits apply.
Instrument changes stop/reprepare playback and are refused while recording.
Verification includes off-grid move/trim, snap Off, dropdown labels, double-click,
coincident notes, per-note slider/lane edits, invalid velocities, undo/reload and
instrument reuse/clear/reorder for all three fixture formats. Manual checks use
the original modern-session example and the flat sequencer/piano windows.
