## 🚀 Getting Started

### Requirements

- Windows OS
- .NET 10.0 Runtime ([Download](https://dotnet.microsoft.com/en-us/download/dotnet/10.0))
- Any game or application that accepts keyboard input

### Installation

1. Download the latest release from the [Releases page](https://github.com/Psystec/MIDI-Monkey/releases)
2. Launch MIDI Monkey.

## 📝 How to Use

### Basic Setup

1. **Select a MIDI KeyMap Profile**:
   - Choose from the built-in profiles or create your own
   - Each profile maps MIDI notes to specific keyboard keys

2. **Load MIDI Files**:
   - Click "Select MIDI Folder" to load your MIDI files
   - Select a MIDI file from the list

3. **Start Playback**:
   - Make sure your game/application is running
   - Click "Play Song" or press F5 to start playback
   - Press F6 to stop playback at any time

### Using a MIDI Keyboard

1. Connect your MIDI keyboard or device to your computer
2. Select it from the "MIDI Device" dropdown
3. Click "Use MIDI Device"
4. Play notes on your MIDI keyboard - they will be automatically translated to keypresses

### Creating Custom KeyMaps

1. Navigate to the 'MIDIKeyMaps' folder in your installation directory
2. Create a new JSON file with the following structure:

```json
{
  "ApplicationName": "YOUR_GAME_PROCESS_NAME",
  "KeyMappings": {
    "60": [ "LeftShift", "Q" ],
    "61": [ "", "Number2" ],
    "62": [ "LeftControl", "W" ],
    "63": [ "", "Number3" ],
    "64": [ "", "E" ]
  }
}
```

3. The numbers represent MIDI note values (ex. 60 = middle C)
4. The strings represent keyboard keys to press
5. You can add modifiers by including them as the first key:

```json
"48": [ "LeftControl", "Q" ]
```
