MCL / MIDI Configuration

MIDI Configuration

The MIDI configuration menu controls device assignment, port speed, clock, routing, controller input and program-change behavior.

Open it from:

CONFIG > MIDI

The MIDI menu contains:

Entry	Function
`DEVICES`	Assign Grid X and Grid Y devices and ports.
`PORTS` / `TURBO`	Configure MIDI/USB turbo speed. TBD shows the flattened `TURBO` menu. MegaCommand and MegaCMD use `PORTS` with `PORT 1`, `PORT 2` and `USB` sub-pages.
`SYNC`	Configure clock and transport receive/source plus clock and transport send.
`ROUTING`	Forward non-realtime MIDI between ports.
`CONTROLLER`	Configure live input and output forwarding.
`PROGRAM`	Configure program-change driven loading.

Changes are applied when leaving the relevant menu.

Devices

The device setup menu assigns the device and port used by Grid X and Grid Y.

CONFIG > MIDI > DEVICES

Entry	Function
`GRID X`	Primary grid device and port.
`GRID Y`	Secondary grid device and port.

MegaCommand / MegaCMD Device Options

Grid	Device options	Port options
Grid X	`OFF`, `MD`	`MIDI 1`, `USB`
Grid Y	`GENER`, `ELEKT`, `OFF`	`MIDI 2`, `USB`

TBD Device Options

Grid	Device options	Port options
Grid X	`OFF`, `MD`, `TBD`	`INT`, `MIDI 1`, `USB`
Grid Y	`GENER`, `ELEKT`, `TBD`, `OFF`	`INT`, `MIDI 2`, `USB`

Use OFF for an unused grid. Changing device assignments affects how projects map stored grid slots to devices.

Ports and Turbo

MegaCommand and MegaCMD use:

CONFIG > MIDI > PORTS > PORT 1
CONFIG > MIDI > PORTS > PORT 2
CONFIG > MIDI > PORTS > USB

Each port has a TURBO setting.

Hardware	Turbo options
MegaCommand / MegaCMD	`1x`, `2x`, `4x`, `8x`
TBD and desktop	`1x`, `2x`, `4x`, `6.7x`, `8x`, `10x`

TBD shows the turbo settings directly under:

CONFIG > MIDI > TURBO

For Machinedrum MK1 units, use 4x or lower.

Sync

CONFIG > MIDI > SYNC

Entry	MegaCommand / MegaCMD	TBD
Clock receive/source	`CLOCK RECV`: `1`, `2`, `USB`	`CLOCK SRC`: `1`, `2`, `USB`, `INT`
Transport receive/source	`TRANS RECV`: `1`, `2`, `USB`	`TRANS SRC`: `1`, `2`, `USB`, `INT`
Clock send	`CLOCK SEND`: `OFF`, `2`, `USB`, `2 + USB`	Same send options
Transport send	`TRANS SEND`: `OFF`, `2`, `USB`, `2 + USB`	Same send options

Use the same receive/source for clock and transport unless transport intentionally comes from a different source.

On TBD, the send settings choose external MIDI/USB ports. The internal TBD connection is handled automatically when TBD is assigned to either grid.

Routing

CONFIG > MIDI > ROUTING

Routing forwards non-realtime MIDI traffic between ports.

Entry	Function
`MIDI 1 FWD`	Forward data received on MIDI 1 to `OFF`, `2`, `USB`, or `2 + USB`.
`MIDI 2 FWD`	Forward data received on MIDI 2 to `OFF`, `1`, `USB`, or `1 + USB`.
`USB FWD`	Forward data received on USB to `OFF`, `1`, `2`, or `1 + 2`.

The old CC LOOP routing entry is not exposed.

Controller Input

CONFIG > MIDI > CONTROLLER > INPUT

Controller input is used for chromatic play, drum triggering, polyphonic input and live recording.

Entry	Function
`PORT`	Selects the controller input port: `2`, `USB`, or `2 + USB`.
`CHRO CHAN`	MIDI channel for chromatic play: `--` or `1..16`.
`TRIG CHAN`	MIDI channel for drum-pad triggering: `--` or `1..16`.
`POLY MODE`	`INT` uses internal note data only; `INT+EXT` also responds to external controller input.

Controller Output

CONFIG > MIDI > CONTROLLER > OUTPUT

Entry	Function
`NOTE FWD`	Forward controller note input to the configured secondary-device output when enabled.
`CC FWD`	Forward controller CC input to the configured secondary-device output when enabled.
`MUTE CC`	Selects the CC used to send or receive external track mute state, or `--` to disable it.

Program Change

CONFIG > MIDI > PROGRAM

Entry	Function
`PRG MODE`	`BASIC` or `ADV`.
`PRG IN`	Program-change receive channel: `--`, `1..16`, or `OMNI`.
`PRG OUT`	Program-change transmit channel: `--` or `1..16`.

BASIC mode loads a full row according to the active load-page mode and group selection.

ADV mode sets the row used for incoming note-triggered slot loads. Notes from C4 upward select slots to load from the current or most recently selected row.

MCL cannot load slots instantaneously; plan for at least one bar of lead time when driving loads from external program changes or notes.
