Hi Group,

Is there anyone on this forum controlling a T4, or any of the Tyros series directly from an accordion or control keyboard?

I want to be able to change sounds on the T4 via the Registration buttons on the Roland 7X accordion. These buttons can transmit cc00, cc32, and PC as well as after touch, pitch bend, velocity ETC.

I can already control the T4, i.e. play styles and sounds however I have to change sounds and styles from the T4 itself, or use a footswitch!

I have all the info on Tyros sounds (ccoo, cc32, PC) from Yamaha's Data Sheet Manual, however when I program them to a registration button and push that button, nothing happens. The sound doesn't change.

I called tech support at Yamaha and they couldn't help me! I find this very curious! Roland tech support couldn't help either.

The deeal is this. I have 14 buttons available on the accordion in each set. And I have 80 possible sets. So the possibilities are endless; if I can just get it to work.

The 7X accordion is quite capable of sending the proper MIDI messages; Don't know what I'm doing wrong!

Any help is greatly appreciated.
Thanks
Don P
