Ctrl+Shift+Left/Right move every note in the take by one grid cell, for clips that landed off the beat. Since the whole take moves together, notes cannot collide with each other; the hazard is the item boundary. Notes pushed past either end stop sounding but are not deleted, so the operation is reversible -- shifting back restores them. The plain keys still refuse when that would happen and report the count, because a clip that has silently lost its first bar is a bad thing to discover later. Ctrl+Alt+Shift forces it and names the consequence. Positions are converted through QN rather than offset in raw ticks, so shifts stay musically correct across tempo changes.

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
