In your case you would use a low pass filter in the internal side chain of the compressor...
Peter this is the absolute opposite of what I was suggesting. An LPF in the side chain would make the compressor more sensitive to low frequencies.
Oops sorry, my mistake. I did mean
HPF.

But that compresses everything

Precisely. That's the intention. Every time the louder high notes the original poster wants softened are struck the compressor kicks in to turn them down a little (soften). This is how a typical deesser work as well.
Well, a de-esser is allowed to turn everything down because a voice is monophonic. I think we cannot solve the problem unless we hear what's going on. If he plays only high notes, the normal compressor with an internal HPF will do just fine. But if he plays low keys with the other hand, it might sound funny when the whole volume goes down with the heights.
Maybe there are some psychoacoustic phenomenes I don't know and a sidechained single band compressor would indeed work, but I rather think he looks for an automatic hand on the hi-shelve knob. That's why I pointed to Sonalksis software, their DQ1 does exactly that and, btw, allows a peak filter instead of the shelve in case this works better for the given sound:
Mhm, I have no clue what the technical difference between a dynamic EQ and a multiband compressor is. Does anybody know the answer?
