Good afternoon, everyone.
Fred, miking a piano and getting good quality results is a bit of an art and is dependent upon the quality of the microphones, the voicing of the piano, and the performance itself.
I think that the place to start is with the performance itself. If you are not happy with the playback of the recording on the Disklavier, that means that the performance either needs editing or--if the playback is different from the original performance--the piano needs calibration and possibly mechanical adjustment.
Any MIDI sequencer will let you edit the individual velocities of the notes. If you want to "reduce the effect of the note attack," you probably need to reduce the velocities of the problem notes.
The sustain pedal ranges in MIDI value from 0 (Off) to 127 (fully engaged). If you look at the dampers inside the piano, you'll notice that there is a point at which they are fully off the strings. From that point to the point of fully engaging the pedal, there is no additional benefit to higher values for controller 64.
Somewhere in the range of MIDI values 1 to 60 or 70, there is an area in which the dampers are slightly but not fully dampening the strings. If you find that the pedaling sounds muddy, this probably means that the pianist is never fully releasing the pedal (i.e. generating a value of 0), and the result is some muddiness of the sound. If that is the way that the original performance sounded, the pianist should either record the piece again, giving attention to the full release of the pedal, or you will have to do some sophisticated editing of the pedal data. A sequencer that gives you a graphic view of the pedal data can be very helpful in this regard.
On the other hand, if the playback sounds more muddy than the original performance, there may be a problem with the playback of the Disklavier. Iit may be necessary to have the pedal mechanically adjusted and then the instrument calibrated.

My wife is recording on a Disklavier Mark III Control Unit DKC55RCD for the purpose of a recorded audio accompaniment.
1) To perfect the recording, she wants to reduce the effect of the note attack, especially on the lower/bass notes
2) Straight mic is too harsh
3) Mic'ing from DSK speaker output is audio of MIDI and sounds too muddy
4a) Editing the MIDI shows Ch 1 with controller 64 (sustain pedal) AND notes; Ch 2 shows the identical controller and same values as Ch 1
4b) I deleted the duplicate controller channel w/o noticeable affect
5) Converting MIDI to MP3 of course is dependent upon sound card of computer, but the overbearing note attack is still present.
I have an old MIDI editor, MidiSoft/Studio 4 and Cakewalk 7. Right now we are experimenting with limiting the sustain controller to a max value of 100 to see if that has any affect.
Suggestions needed to get a decent audio to remove note 'attack' via MIDI events and/or reduce muddiness of sustain pedal.
Anyone willing to listen to the file and give advice would be greatly appreciated.
