Dusan,
Thanks for the corrections. You're right.
Now if you want to control the SD40's PANEL (Fill in, Start/stop, tempo, transposer ... etc) from the TYROS 5, you will have to make sure the TYROS 5 can send out SYSEXC messages first (not all keyboards have this functionality built in apart form high end controllers). Then, using the SD40's data tables on our website, you will then have to send the required SYSEXCL messages from the TYROS 5 to the SD40 for each action (press X, release X, turn on vocalizer, turn off mic ... etc).
Hope this helps ... first make sure the TYROS 5 does transmit SYSEXEC messages first and that you can edit them - before you proceed.
Thanks,
AJ
