There is one system adjustment that you can try that may improve
repetition performance.  Make sure a PDS disk is in the drive.  Enter
the set-up menu, (press 1 and 4 at the same time).  Cycle through the
menus until you find the "duration" adjustment, (indicated as DUR).

If it is a CD only system, press the "set-up" button on the back of the
control box _twice_ to enter this mode, (make sure you don't press the
DEFEAT button by mistake).  Use the volume up/down buttons to adjust.

When finished select "OK" on the PDS 128 or 228 models, or press
the "PLAY" button, (not STOP), on the CD only models to save the
adjustment.  This adjusts the minimum amount of time any individual
note can be held in milliseconds.  In other words, some piano actions
are not able to repeat fast enough to keep up with the note data.

Adjusting this will either lengthen or shorten the amount of time
a note event will last.  If the duration time is set too long then
notes will slur together because there isn't enough "off" time between
notes and thus will sound like one continuous note.  When adjusting
this the piano will softly play each note progressively up the scale.
Adjust the system so that the majority of them will strike with the
absolute lowest setting possible.

The bass notes don't generally repeat well.  I typically ignore this
and instead make this adjust based on how it performs from the tenor
break on up.  In most music bass notes don't typically need to repeat
fast.  The mid and treble range, however, do.

Keep in mind that _any_ player piano, (either digital or pneumatic),
will only play as well as the piano is capable of performing.  It is
critical that the action be in good regulation for any piano to repeat
notes well.  If it isn't properly regulated, regulate the piano first
and then adjust the duration setting after the work is complete.  This
way the minimal duration setting will be able to be set much lower.

It is amazing to see how much faster an action will repeat and how the
quality of the music will improve when a piano is in proper regulation.
If you are not experienced in regulation work hire a good reputable
piano technician to do the work.  Research and choose one wisely; it
is amazing how many technicians can tune well but can't regulate their
way out of a bucket.

PDS edits their pre-recorded software keeping pace with the typical
owner's lack of proper maintenance.  In other words not by choice they
sometimes sacrifice things like fast repeating notes knowing that the
majority of owners don't always keep their piano in good regulation.
This may explain why it plays well with PDS disks but not from other
MIDI sources.
