Disklavier

I'm using a DC3PRO via the MIDI port (not TO HOST) to a Win98 PC, running
Cakewalk Pro Audio.  I'm also recording multiple tracks-- some piano, and
some other MIDI instruments from other MIDI sound modules.  When the piece
is complete, I always have the 500ms delay on (it's way too inconsistent
without that), and I compensate in the sequencer as follows...

1) When initially developing and recording the piece, I don't use the piano
for playback at all.  I just set the sequencer track to access the GM MIDI
instrument #1 on the Yamaha sound module.  This is the grand piano sound but
doesn't invoke either the physical piano keys or the amazing "Silent" piano
synth.  It's just a standard MIDI piano sound.  During this stage, I can
turn off the delay, and the Yamaha responds as perfectly as any MIDI box.
Note that I'm still using the Yamaha piano as the controller; just not the
piano as the playback instrument yet.

2) Once all the tracks are laid down, quantized, tweaked, etc., then (and
ONLY then) it's time to invoke the actual piano.  To do this, I go to the
Yamaha console and tell it to have the piano respond to the channel I'm
transmitting on, and then take the Yamaha track (or tracks) in my sequencer
and pull it backward in time (i.e., toward the left) 500ms.  In Cakewalk you
can even record a macro to make this an easy-to-perform operation (which I
did: I call it the "Disklavier Slide").  Now, I turn on the 500ms delay on
the Yamaha, and I'm in business.

This assumes that you're not connecting any other MIDI instruments via the
Yamaha's THRU port.  This is apparently discouraged anyway, though, since
it's impossible to silence the Yamaha on an arbitrary MIDI channel (which
would be necessary if you had another MIDI instrument going through that
same port which you wanted to respond to that channel without having the
Yamaha respond as well).

Anyway, the end result sounds perfect to me.  Seems like you said below that
you have no problems compensating for the 500ms delay, though.  If you mean
that you're doing the same thing I'm doing, but you're still having some
kind of problem, I'd be interested to know exactly what the problem is.  As
far as I can tell, the timing sounds absolutely perfect when I do the above
steps.

Which mode are you recording in? ( XP or Standard)  Have you tried using the
host port instead of the midi ports?  Midi interfaces are notorious for
"coloring" the data.


Anyone else using the Disklavier Pro for Computer/MIDI dissapointed w/
the midi lag on midi out of the DK. Any tweaks for better response?

I just took delivery of my new DC7 PRO and the internal recorder is 98%
there and great for the home market, but using it for precise
(professional, real time, jazzy ) midi recording has been time consuming
and has me dissolutioned. I have no problem compensating for the 500 ms
delay on a ghost track for piano playback, but this is not
"profesional".

Local mode sounds fine in Silent. I am recording into PC / VST / LOgic
.  But when I go to Local off ( Midi thru the PC) I experience what
feels like 3-8ms delay. Not fun for playing tight. Also, the events
appear late on the edit screen so selectively quantizing notes moves
them farther away from the unquantized ones. Not acceptable.

Another BIG  problem: the midi note length on output is shorter >  I can
tell the difference both while I'm playing other piano synth module
sounds and especially on playback of fast passages to the DK.


I'm considering returning this if I find this problem to be unfixable.
Any ideas??



Thanks,
Gregg
