MIDI Transport (Prev / Next)
Notes 101 and 102 step backward and forward through the assignments in the active configuration slot.
The MVP now responds to two dedicated MIDI notes that step backward and forward through the assignments in your currently active Configuration Slot. This turns any MIDI controller with two free buttons or pads into a show navigator.
These two notes are hardcoded and cannot be reassigned. They live outside the 1–99 trigger range so they never collide with your clip assignments.

How It Works
When the MVP receives Note 101 or 102 on the Video Channel, it steps the video transport. When it receives them on the Lighting Channel, it steps the DMX transport. The two domains are independent. You can advance video without disturbing the running DMX clip and vice versa.
Stepping always operates within the currently active Configuration Slot (A through E). The transport will:
Skip empty assignments — if Note 3 is empty and you press Next from Note 2, the system jumps directly to Note 4.
Wrap around — pressing Next on the last assignment returns you to the first; pressing Prev on the first goes to the last.
Stay inside the active slot — Prev/Next never crosses into another slot.
If nothing is currently playing on the channel (blackout, default video, or boot) Prev/Next starts from the first non-empty assignment in the active slot.
Where to Find It
There is no toggle — the Prev/Next notes are always active. Documentation for the feature is mirrored in System Settings → MIDI Transport (Prev / Next) so you have a quick on-device reference.
Repeated Notes: The Drumstick Problem
Hardware MIDI controllers can sometimes be very sensitive, and unintentionally send the same note twice within a few milliseconds when struck. Without protection, a single drumstick hit could advance two clips.
To prevent this, the MVP enforces a 300 ms delay per direction:
After receiving Note 102 (Next), any further Next notes within 300 ms are ignored.
The Prev direction debounces independently — you can press Prev right after Next without one blocking the other.
300 ms is long enough to absorb every double-trigger we've seen from real hardware, but short enough that intentional rapid stepping (three or four clips in a row) still feels responsive.
Interaction with Other Features
Timecode — when LTC or MTC is actively driving playback, Prev/Next is suppressed. The timecode source owns the transport. Stopping timecode re-enables Prev/Next.
Autoplay — Prev/Next is treated as autoplay navigation, not as a "disable autoplay" command. After stepping with Prev/Next, autoplay continues to advance at the next end-of-clip.
Loop Mode Override — independent of transport. Prev/Next steps to the next clip regardless of how the current clip is configured to behave at end-of-video.
Blackout (Note 0) — clears the current position. The next Prev or Next starts fresh at the first non-empty assignment.
