Disklavier

Good morning, everyone.

Carol, any good sequencer with a graphical interface should make it pretty straight forward to edit pedal data.

The piano pedals are MIDI controllers:

Sustain = Controller 64
Sostenuto = Controller 66
Una Corda =  Controller 67

Sustain and una corda range in value from 0 (fully off) to 127 (fully on). 

Somewhere in the range of 0 to 40 or 50, the sustain pedal should be in the lost motion area in which the dampers have not yet left the strings. In the approximate range of 40-80, there should be some amount of partial damper contact with the strings. Beyond that, the dampers should be off the strings.

The Sostenuto pedal only records values of 0 and 127 and does not move on playback. However, on playback the Disklavier will hold down the keys of the notes that were captured by the sostenuto pedal.

If you are working from older E-SEQ files that were translated to SMF, you may find that the notes and on/off pedal data are on channel 1 or channels 1 + 2 and that the incremental pedal data is on channel 3. For playback on a Mark IIXG or more recent instrument, you should merge the incremental pedal pedal into channel 1 (or channels 1 + 2).

I presume that Logic has both an event list view and a graphic view. I have found that incremental pedal data is pretty easy to manipulate in graphic view using Digital Performer on the Mac. Other sequencers with a graphic UI should be similar.

I am puzzled that many of your files are corrupted. That seems doubtful, and I wonder if those files deserve further investigation.

As for sustain pedal noise: You might look at the pedal data and see if there is incremental pedal data or just on/off pedal data. The lack of incremental data would mean that the instrument needs to move the pedal quickly from 0 to 127 and back again. However, the Disklavier does have a built-in algorithm for doing this smoothly. I don’t have a problem with on/off pedal data with my Disklavier PRO. However, the PRO solenoids probably perform in a more nuanced fashion. I would check the mechanical regulation of the pedals and then recalibrate the instrument.

For years I auditioned my MIDI files using the computer synthesizer. Now I can listen to them actually playing the piano! To my surprise, many files are corrupted and won’t play from my computer, but I can redo those and test them in real time.

To be specific, since I am operating on an iMac running Sierra, I will be using Logic Pro 9 to edit MIDI files providing I figure out how to even load a MIDI file and find the controller.
