Midi Reference
A complete reference for all MIDI notes, CC messages, and channels used by the MVP.
MIDI Channels
Video Channel
Channel 1 (MIDI channel 0 internally)
Yes (1-16, in System Settings)
Lighting Channel
Channel 3 (MIDI channel 2 internally)
Yes (1-16, in System Settings)
Video and Lighting channels are configured independently. Channels are reloadable at runtime -- changing the setting takes effect immediately.
MIDI Notes -- Clip Triggers
Sent on the Video or Lighting MIDI channel:
0
Blackout -- Video: loads blank video (black screen) / Lighting: loads DMX blackout (all channels to 0)
1-99
Trigger the clip assigned to that note number
100-109
(unused)
110
Reset ALL Effects Mode properties to defaults (video channel only)
111
Reset Brightness to 0 (video channel only)
112
Reset Contrast to 1.0 (video channel only)
113
Reset Hue to 0 (video channel only)
114
Reset Saturation to 1.0 (video channel only)
115
Reset Rotation Z to 0 (video channel only)
116
Reset Scale to 1.0 (video channel only)
117
Reset Translation X to 0 (video channel only)
118
Reset Translation Y to 0 (video channel only)
119-126
(unused)
127
Config Reload -- Video channel: reload video config / Lighting channel: reload lighting config
Note Handling Details
Velocity: Any velocity > 0 triggers the clip. The specific velocity value does not matter.
Velocity 0: Treated as Note Off and ignored.
Note Off: Completely ignored -- the MVP does not respond to Note Off messages.
Re-trigger: Sending the same note while a clip is playing restarts it from the beginning.
Timecode suppression: When timecode is active, MIDI note triggers for video and DMX are suppressed.
MIDI CC -- Effects Mode Controls
Sent on the Video MIDI channel only. Requires Effects Mode (transform video mode) to be active.
48
Brightness
64 (normal)
0 = darkest, 64 = normal, 127 = brightest
49
Contrast
64 (normal)
0 = minimum, 64 = normal, 127 = maximum
50
Hue
64 (normal)
0 = full shift left, 64 = normal, 127 = full shift right
51
Saturation
64 (normal)
0 = grayscale, 64 = normal, 127 = oversaturated
52
Rotation Z
0 (no rotation)
0 = no rotation, 127 = full 360° rotation
53
Scale X/Y
64 (100%)
0 = smallest, 64 = normal size, 127 = 200% zoom
54
Translation X
64 (centered)
0 = far left, 64 = centered, 127 = far right
55
Translation Y
64 (centered)
0 = far up, 64 = centered, 127 = far down
Effects are grouped into two categories:
Color adjustments: Brightness, Contrast, Hue, Saturation (CC 48-51)
Spatial transforms: Rotation Z, Scale, Translation X/Y (CC 52-55)
MIDI CC -- Slot Switching
Sent on the Video or Lighting MIDI channel:
119
10
Switch to Slot A
119
20
Switch to Slot B
119
30
Switch to Slot C
119
40
Switch to Slot D
119
50
Switch to Slot E
119
0
(ignored -- common DAW reset value)
Important details:
CC #119 on the video channel switches the video slot only
CC #119 on the lighting channel switches the lighting slot only
Only the exact values above are accepted -- values like 11, 25, or 35 are silently ignored
If the requested slot is already active, the switch is silently skipped
Timecode does NOT support CC #119 slot switching -- timecode slots can only be changed from the UI
MIDI CC -- CC Trigger Mode
Must be enabled in System Settings (CC Trigger Mode toggle).
Sent on either the Video or Lighting MIDI channel:
110
1-99
Trigger the clip assigned to that number
110
100
Trigger blackout (maps to note 0)
110
0
(ignored -- default/off value)
110
101-127
(ignored -- out of range)
Warning: Do not use with faders or knobs (continuous controllers) -- use buttons only. Each distinct value fires a clip change immediately.
MIDI Note Numbering Conventions
Different DAWs and controllers use different octave numbering. The MVP uses raw MIDI note numbers (0-127). Here's how they map across common conventions:
0
C-2
C-1
C-2
12
C-1
C0
C-1
24
C0
C1
C0
36
C1
C2
C1
48
C2
C3
C2
60
C3
C4
C3
Tip: If you're unsure which note number your controller is actually sending, check the MVP Dashboard's Input Monitor -- it always shows the raw MIDI note number regardless of naming convention.
MIDI Machine Control (MMC)
Received via any MIDI input when MTC is active (SysEx and timing messages are unfiltered):
Stop
Freeze video on current frame, lighting holds last state
Play
Resume playback from current or pending Locate position
Pause
Same as Stop -- freezes current state
Locate/GoTo
Seek to specific timecode position
MTC Routing
MTC messages are handled separately from regular note/CC messages:
Timecode data: Continuous timecode tracking for synchronized playback
Position jump: Sent when your DAW scrubs or locates -- provides immediate absolute position
Transport commands (MMC): Stop, Play, Pause, and Locate for controlling the MVP's playback state
