Hi Keith ,
I decided to try the sd2 with my PSR1500.

I've been working on converting a sd1 style to OMB ( psr) .sty format, just to see how close I could get to the original sd1 style using the sd2 with OMB.

Anyway decided to try loading it into the psr instead & use the sd2 as soundsource.

Discovered the following.
On my PSR 1500 , I Can't use a mix of PSR & SD2 sounds for the "style parts"
ie sd2 drums, psr bass, sd guitar etc etc
as there appears to be no way of turning
local control to "Off" for individual style part instruments. ( maybe Tyros has better midi functions???)

I can turn local controll to "Off" for the style tracks as a whole & use my psr voices for melody & left hand , & the SD2 plays the style part instruments.

Not the most ideal setup if you only use
" Tyros " styles. They naturally wouldn't play back correctly because of the megavoices & the psr drum mapping.

If on the other hand you create your own styles , or use tweaked conversions it would be a case of tweaking to suit the sd2 soundsource instead of the Tyros.

Unfortunately my psr hasn't got the same flexibilty for using multiple soundsources as OMB has.

best wishes
Rikki
