The most important instruments for a keyboard player are Piano,El. Piano,Organ,Synth...And for the Studio sequencing the most important instruments are Drums,Bass.....
We have Drums and El. Piano ARX's and almost half of the job is done.
I think that Organ sound should be better and Brass also.But we already have Brass ARX.
So what's left is Organ,Synth,Piano,Bass.
Personaly I would like to have Bass ARX.Or maybe Bass&Guitar ARX what is maybe the best combiantion.Some powerfull Analog Synth would be great.
Piano and Organ is not for me.I already have DRUM ARX.
Also would be great to see some kind of a STUDIO ROM PATCHES expansion with Bass,Ethnic sounds,Guitars,Electronic Drums,Strings,Organs,Woodwinds.....
But I dont think that Roland will make Piano ,Organ ,Synth ARX becuse of the other Roland gear like V-Piano,V-Synt,Organ gear....
I think that Orchestra,Strings or maybe Ethnic sound will be next ARX.
I would lik my next ARX to be for LIVE gig also.
And one thing more.I dont think that Roland will make something like SRX ROM Patches ARX.That is past.Modeling is something that Roland will develop in the future.Modeling is great thing.
