I would have no problem with it...I had the same setup for many years when I played in a combo.

It would feel very unnatural playing two-handed piano on semi-weighted keys...that would be a problem for me...I could deal with 76 keys, but I would at least want them weighted, even if they weren't graded hammer...even the T3's lovely FSK, considered to be one of the very best feeling semi-weighted keyboards, stretched to more than 5 octaves, wouldn't appeal to me for two handed piano.

The next ideal arranger setup for me is what I have now...61 light action keys, small and very transportable cabinet, built in speakers...thankfully already available.

After that, it would be a 76 note weighted hammer arranger, the same, or a bit heavier than the 25 lb P-85...a lightweight CVP, no less.

I tried using the P-85 under the PSR-S910 and the awkward access to style and registration buttons, and the pitch/mod wheels, made it a no go for me.

For the very rare occasions I played a gig which required both solo piano, and arranger music, it was very easy to put the P-85 and an X-stand in with the other gear, and it made the job very enjoyable.

Remember, Cassp's #4 question was, "What would you (meaning us, as individuals) require in a 2-manual arranger?"

Not the general buying public.

That's how I understood the question.
