> A Lua/ReaScript that turns the computer keyboard into a MIDI input device for REAPER — notes, octave shifts, and mod wheel without any external controller.

## Facts

- **Roles**: Implementation
- **Year**: 2025
- **Version control**: Git
- **Language**: Lua / ReaScript
- **Host app**: REAPER
- **Status**: Completed

## Case file

- **Workflow result**: A computer keyboard that plays notes, shifts octaves, and drives the mod wheel through a single activation toggle.
- **Context**: Quick MIDI entry for sketching, sample triggering, and portable workflows without a physical MIDI keyboard.

## Problem

Sketching a melody or triggering samples normally requires a MIDI keyboard
within reach. On the go, on a laptop, that is not always possible — and
setting up extra hardware just to test an idea breaks the workflow.

## What the script does

LogicKeyboard turns the computer keyboard into a MIDI input device for
REAPER: keys play notes, dedicated shortcuts shift the octave, and the mod
wheel stays reachable. The script ships in both QWERTY and AZERTY layouts,
and a toggle starts or stops it without leaving the workflow.

## Why it matters

This is the classic case of a small tool removing real friction: a MIDI
keyboard stops being a prerequisite for capturing a musical idea. The
Logic Pro-inspired workflow fits naturally into REAPER habits, and the
script remains a single file to import into the Action List.
