Don,
The trick is in the Tyros 5 Midi set up.
On the TYROS 5,
* Go to Function
* Go to MIDI Transmit and set LEFT = 2 but ... you must (on the panel) turn on the LEFT voice but lower it's volume to 0 so you do not hear it but it still triggers the SD7/Midjay Pro!
* Set Right1= 1
If you want to get fancy (as we did in the Detroit workshop), turn on the TYROS 5 Midi clock (ext=on) and on the SD7/Midjay Pro, turn off Internal Mid Clock.
Make sure you go through the other TYROS 5 Midi Transmit channels and turn off anything transmitting on Channel 2!
This gives you tempo control from the TYROS 5 and now, you can also trigger the Multi Pads of the Tyros 5 and they will be in sync with the SD7/Midjay Pro's styles!
Hope this helps.
Thanks,
AJ
