Ctrl+Alt+Space plays the cursor's bar and stops at the next bar line, so the same bar can be fired repeatedly while nudging a note without reaching for stop. Alt+Space keeps its play-onwards behaviour. The stop is performed by the preview daemon rather than the action script: a script that stayed alive waiting for the bar to end would bring back REAPER's "already running" prompt on the next press, which is the problem the daemon exists to avoid. Stopping transport can move the edit cursor depending on preferences, and the edit cursor is the grid cursor, so the daemon restores it. A short arming window covers the gap between requesting playback and the transport reporting as playing, so the pending stop is not cancelled instantly.

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
