Triggering Overview

The MVP supports multiple ways to trigger video and lighting clips. You can use any combination of these methods simultaneously -- the last trigger received wins.

MIDI Note Triggering

The most common method. Your DAW, controller, or show system sends a MIDI note on the configured channel.

Note
Action

Note 0

Blackout (video goes black / DMX all channels to 0)

Notes 1-99

Trigger the clip assigned to that note number

Note 101

Previous -- step back to the previous non-empty assignment in the active slot

Note 102

Next -- step forward to the next non-empty assignment in the active slot

Key details:

  • The video MIDI channel (default: 1) and lighting MIDI channel (default: 3) are configurable in their respective settings pages

  • Note On starts playback; note duration is irrelevant

  • Stopping your DAW does not stop the MVP -- send Note 0 (blackout) to explicitly stop playback

DAW-specific setup: Ableton | Pro Tools | Logic Pro | Other DAWs

MIDI Transport (Prev / Next)

Two hardcoded notes step through the assignments in the currently active configuration slot.

  • Note 101 = Previous, Note 102 = Next

  • Sent on the video channel they step video; on the lighting channel they step lighting

  • Empty assignments are skipped; stepping wraps within the active slot and never crosses into another slot

  • Debounced at 300 ms per direction to absorb double-triggers from hardware pads

  • Always active -- there is nothing to enable

Details: MIDI Transport (Prev / Next)

MIDI CC Trigger Mode

An alternative to note triggering is using Control Change messages.

  • Uses CC #110

  • Values 1-99 = trigger clip, value 100 = blackout

  • Must be enabled in System Settings

Details: MIDI CC Trigger Mode

USB Keyboard Triggering

Any USB keyboard or numeric keypad connected to the MVP's USB-A ports can trigger clips.

  • Number row (1-0) = clips 1-10

  • QWERTY rows = clips 11-36

  • Shift + key = lighting clips

Always enabled, no configuration needed.

Timecode Playback

For timeline-based show playback synced to SMPTE timecode.

  • LTC: Audio timecode via 3.5mm input

  • MTC: MIDI timecode via USB, DIN, or Network MIDI

  • Supports continuous sync, variable speed, and transport control (MMC)

When timecode is active, manual triggers (MIDI notes, keyboard, CC) are suppressed.

Details: Timecode Overview | Timeline Editor

Hardware Controllers

MIDI controllers (USB or 5-pin DIN) can trigger clips directly without a DAW.

  • Any class-compliant MIDI device works

  • Multiple controllers can be connected simultaneously

Details: Hardware Controller Setup

Network MIDI (RTP-MIDI)

Send MIDI triggers wirelessly over Ethernet or Wi-Fi using the RTP-MIDI protocol.

  • Works on Mac natively (Audio MIDI Setup)

  • Works on Windows via free rtpMIDI app

  • The MVP advertises as "MVP" on the network

Wiring Diagrams

Depending on your production needs, your setup will look like one of the following diagrams:

Scenario A: Video Playback Only

  • Signal Chain: Computer → MVP → HDMI Display

Scenario B: Lighting Playback Only

  • Signal Chain: Computer → MVP → Ethernet → ArtNet Node → DMX Fixtures

Scenario C: Video + Lighting Playback

  • Signal Chain: Computer → MVP → HDMI & Ethernet

Scenario D: Standalone (No Computer)

  • Signal Chain: MIDI Controller → MVP → HDMI & Ethernet

Trigger Priority and Interaction

  • All methods are active simultaneously -- MIDI notes, CC, keyboard, and timecode can all be connected at once

  • Last trigger wins -- if two triggers arrive at the same time, the most recent one takes effect

  • Timecode overrides manual triggers -- when timecode is actively driving playback, manual triggers (MIDI notes, keyboard, CC) are suppressed to prevent conflicts

  • When timecode stops, manual triggers resume automatically

  • Autoplay is not a trigger method -- when enabled it advances at the end of each clip, and manual triggers (including Prev/Next) simply move the playhead without switching it off. See Autoplay.

Slot Switching During Performance

You can switch between configuration slots (A-E) during a live show using MIDI CC #119:

CC #119 Value
Slot

10

Slot A

20

Slot B

30

Slot C

40

Slot D

50

Slot E

Video and lighting slots switch independently -- send CC #119 on the video channel to switch video slots, or on the lighting channel for lighting slots.
