The QRS PNOScan II, which I have installed in my upright player piano, has velocity sensing.
Neither gives the same quality result as the recording disklaviers as they miss the hammer velocity sensing.
Hi Geoff,
Perhaps my phrasing wasn't clear; the Disklavier generates MIDI velocity by combining key depression timings as well as measuring the velocity that the hammers strike the strings (this is what I meant by hammer velocity sensing, as opposed to simple MIDI velocity) - the two combined giving a very good result. The PNOScan is ultimately limited to key movement, unless I've missed something!
Recent disklaviers (III Pro, IV) also include full key movement recording and reproduction, so you get non-sounding key depressions and partial depressions also recorded. I believe the PNOScan is also able to do some of this, but you will be in a far better position to comment on that capability than me!
Regards,
James
