Hi Oleg,
as far as I'm aware, keyboards do send out program changes ( or at least they used to).
I tried connecting a number of my keyboards to various synth modules over the years.

Problem was the bank & program changes within the style won't neccasarily match your sound modules program & bank changes.
Only way around it was to edit the styles and put in the correct bank , program change no's, adust volume etc etc.

It sort of worked with hardware sound modules ( though an awful lot of work and I gave up), don't know how you'd go with softsynths.

best wishes
Rikki

If the new NI software accepts program changes, then the only issue left would be to make the arranger keyboard to send out program changes for each part of a style. It will be interesting to try this and compare the sound quality, sample load time, etc.
