Chords are built by stacking scale thirds rather than from a quality table, so the chord follows the degree automatically -- in C major, Alt+3 on C gives C major, on D gives D minor, on B gives B diminished. Toggling delegates to toggleCell, so chord tones inherit hold-mode joining, splitting and trimming unchanged. Velocity keys act on the note under the cursor if there is one, and on the default for new notes otherwise, announcing which. That avoids a mode switch between setting a level to draw at and shaping dynamics after the fact. Also fixes install.ps1 failing to resolve its own directory: $PSScriptRoot is not reliably populated during parameter binding, so it is resolved in the body. Tests cover chord quality per scale degree and range clamping.

MIDI Grid installer.
|
|
|
|
Registers the scripts as Reaper actions and binds them, by editing
|
|
reaper-kb.ini directly. This is done rather than via "Import key map"
|
|
because Reaper's importer silently converts unresolved script bindings
|
|
into "No-op (no action)" entries -- see README, Installation notes.
|
|
|
|
REAPER MUST BE CLOSED. It rewrites reaper-kb.ini on exit and will
|
|
discard anything written while it is running.
|
|
|
|
Usage: powershell -ExecutionPolicy Bypass -File install.ps1
|
|
powershell -ExecutionPolicy Bypass -File install.ps1 -Uninstall
