Thank you AJ,

for short guide.On Tyros setings you prabably mean:tab to Midi TRANSMIT and not to Midi RECEIVE...
Tyros shuld to be MASTER kayboard and SD 40 shuld to be SLAVE.
Tyros in Midi menu has by defolt many presets and two of them is caled MIDI MASTER KBD 1&2.If I dont set enithing in that two menu SD40 work yust fine.Also work Transpose button and SD emedetly change musical kay.Allso I can control Midi Clock that mean SD40 Style tempo is the same like in chousen Tyros Style.
Problem is how to set Midi data to control Style variation with Tyros button's and Brake.SD40 react on Stop button ,Sinhro Stop Button allso with Intro and Ending Tyros button's.
Tyros Styles sound's amazing with Tyros acompaniment and SD40 Audio drums in sinhronization....
And on the end,what is the problem about Style Modeling?
