Hi Richard,
These are MIDI SYSEX messages, I'm not sure whether HW can/will auto detect these.
If not, it looks as though you might be able to set them up manually:
Right click on the HW piston you want to control.
Choose "Adjust MIDI/trigger stings manually..."
Under 'Primary Input' choose the Input: setting "Generic MIDI sysex constant messages" and tick the 'momentary piston' box just below.
Use the scroll bar on the right hand bottom of the setup screen and scroll to the bottom.
Enter the numeric information into the first six boxes.
Press 'OK' and hope for the best.
I can't/haven't confirmed that this will work, but it looks as though it ought to.
Nick
