3.1 Basic MIDI Routing

The MIDI Express XT provides 8 independent MIDI inputs and 8 independent MIDI outputs. Each port can transmit and receive MIDI data simultaneously. Routing of MIDI signals between ports and to/from your computer is managed through the MOTU ClockWorks software (or similar control panel software provided by MOTU).

3.2 SMPTE Timecode Synchronization

The MIDI Express XT supports SMPTE timecode generation and synchronization. This allows you to lock your MIDI sequences to external video or audio sources, or to generate timecode for other devices. Configuration for SMPTE read/write functions is performed within the MOTU control panel software.

3.3 MIDI Merge Matrix

The device features a MIDI merge matrix, enabling you to combine MIDI data from multiple sources into a single stream. This is useful for complex setups where several controllers need to send data to one instrument or software application. The merge functionality is configured via the MOTU control panel software.

3.4 Software Control

All advanced settings, including MIDI routing, merging, filtering, and SMPTE options, are controlled through the dedicated MOTU software application installed on your computer. Refer to the software's help documentation for detailed instructions on specific configurations.
