Midi patch/midi channel choice?

Hi.

I am creating track presets with Kontakt players with multi instruments and related cubase midi tracks for each of the instruments in the multi

eg all the Albion 1 string patches in one Kontakt each with a different output and a different midi channel plus the matching midi channels in cubase.

When I am on the track preset save screen I get the choice of ‘include midi patch’ or include ‘midi channel’

I have looked in the manual and in the on line help to see what this actually means in the context of resulting saved patch but I can’t find anything.

I’d be grateful if anyone could enlighten me.

Thanks

Ben Harris
