Rikki - many thanks for replying.
My old dad has got a programmable midi controller that would probably help me overcome some of the potential problems.
For example it can filter out any number of channels so you can just leave channel 10 thru for drums. It can be programmed to send any string of midi commands.
However - I may not need to, I will check out what can selectively be transmitted using the Tyros2 midi settings first when I am next with the keyboard (I have looked in the manual but you can't tell from that).
So it may be quite convoluted accessing some of the sounds but I think I will get one anyway even if it is just to play around with as the street price here is pretty good.
Thanks again
Regards - Keith
