Found this on page 5 of the Voodoo Lab Hex manual on the web:
Use with Other MIDI Controllers You can use HEX with any controller capable of sending MIDI Program Change or Control Change messages.
To do this, you must setup HEX to respond to the appropriate MIDI messages.
Saving and Recalling Presets You can save and recall preset loop combinations using MIDI Program Change (PC) messages. Set HEX to respond to PC messages (SETUP: Enable MIDI Messages). HEX will use MIDI channel 1 by default. Make sure HEX and your MIDI controller are both set to the same channel.
1) Select the program number with your MIDI controller that you want to create. This will send the PC message to HEX.
2) Set the HEX loops to the desired combination.
3) Press HEX buttons #1 and #6 at the same time. The LEDs will blink to confirm that you saved the preset.
Now whenever HEX receives this PC message, it will recall your loop settings.
So, you can load a loop ensemble via one program change. What needs to be done on the PROFILER side is explained in the Main Manual, section "MIDI", paragraph "Transmitting MIDI Commands to Two
External Devices in Performance Mode".
