# Logic Pro Setup

This guide covers setting up Logic Pro to trigger video and lighting clips on the MVP via MIDI, and optionally sending MTC for timecode synchronization.

***

## Prerequisites

* MVP connected via USB-C (HOST port) to your Mac
* Video and/or lighting clips assigned in the MVP's [Video Configuration](/2.-video-setup/video-configuration.md) or [Lighting Configuration](/3.-lighting-setup/lighting-configuration.md) pages
* Know your configured MIDI channels (check the Video and Lighting pages -- defaults are Channel 1 for video, Channel 3 for lighting)

***

## 1. Create an External MIDI Track

1. Go to **Track > New Track** (or click the **+** button in the track header area).
2. Choose **External MIDI** as the track type.
3. Click **Create**.

***

## 2. Select MVP as MIDI Output

1. In the **Track Inspector** (left panel), find the **MIDI Output** dropdown.
2. Select **MVP** from the list.

If MVP doesn't appear, check your USB connection. You may need to go to **Logic Pro > Settings > MIDI > Inputs** and verify MVP is visible.

***

## 3. Set MIDI Channel

In the Track Inspector, set the **MIDI Channel**:

* For **video triggers**: Set to your video MIDI channel (default: **Channel 1**)
* For **lighting triggers**: Set to your lighting MIDI channel (default: **Channel 3**)

> **Tip**: Set the MIDI Input to **OFF** on your MVP trigger tracks to prevent feedback loops.

## 4. Program MIDI Triggers

1. Open the **Piano Roll** editor (double-click the MIDI region, or press P).
2. Use the **Pencil tool** to draw MIDI notes:
   * **Note 1-99**: Triggers the clip assigned to that note number
   * **Note 0**: Triggers blackout (video goes black / DMX all channels to 0)
   * Note length doesn't matter -- only the Note On event triggers the clip

### MIDI Note Numbering in Logic Pro

Logic Pro's default note numbering convention uses **C3 = MIDI note 60**. MVP note numbers map as follows:

| MVP Note     | Logic Note Name |
| ------------ | --------------- |
| 0 (Blackout) | C-2             |
| 1            | C#-2            |
| 12           | C-1             |
| 24           | C0              |
| 36           | C1              |
| 48           | C2              |
| 60           | C3              |

> **Note**: Logic Pro allows changing note display format in **Settings > Display > General**. If your note names look different, check this setting. The MVP Dashboard always shows the actual MIDI note number -- use it to verify.

## 5. Separate Tracks for Video and Lighting

To trigger both video and lighting from the same Logic session:

1. Create **two External MIDI tracks**.
2. Set both to output to **MVP**.
3. Set the **video track** to your video MIDI channel (default: Channel 1).
4. Set the **lighting track** to your lighting MIDI channel (default: Channel 3).
5. Arrange your video cues on one track and lighting cues on the other.

\[SCREENSHOT: Logic Pro with two MIDI tracks -- one labeled "MVP Video" on Ch.1, one labeled "MVP Lighting" on Ch.3]

***

## 6. Stopping Playback (Blackout)

Stopping Logic Pro does **not** stop the MVP. The last triggered clip continues playing.

To explicitly stop output:

* Draw a **Note 0** at the end of your arrangement or wherever you need blackout
* For both video and lighting blackout, place Note 0 on both tracks

***

## 7. (Optional) Send MTC for Timecode Sync

If you're using the MVP's [Timeline Editor](/4.-timecode-setup/the-timeline-editor.md) for timecode-synced shows:

1. Go to **File > Project Settings > Synchronization**.
2. Under the **MIDI** tab:
   * Enable **Transmit MTC** (MIDI Timecode)
   * Optionally enable **Transmit MMC** (MIDI Machine Control) for transport commands
3. Set the output to **MVP**.
4. Set the **frame rate** to match the rate configured in the MVP's Timeline Editor.
