Disklavier

Walt,

Starting with the source, the 12th St Rag Midi file is strictly 
on/off (up/down) for the sustain pedal, no ands, ifs, or buts. 
Therefore, continuous (HP/Half Pedal) is a mute issue with this 
particular file.In Cakewalk, View | Events and observe Controller 64 
(the sustain pedal) as 127 or 0 --- right down thump alley. In 
Cakewalk or other sequencing program, you can lower the upper values. 
You did not delete all of the pedal info as you have indicated below. 
I still saw Controller 64 data.

I am not familiar with your model DKV (we have a Mark III), and not 
sure of your controller's capabilities with regard to HP data. What 
happens if you record something and observe the Controller values in 
Cakewalk? Are they not in a variable range? How does the thumping 
sound? 

AFAIK, you can redirect only one MIDI channel to the DSK itself 
through the Mark III controller functions, so what you are doing with 
the midi file is just fine. I was referring to a file that already 
had Piano on Channel 1 and 2 and pedal on 3.

thumping. My tech has been trying to resolve it but he is very busy 
and hard to get to come out to work on it. He said that my model does 
not do half pedal like the much more expensive Pro models do. It's 
either all the way down or all the way up. However, he asked me to 
give him some sample midi segments where it is particularly 
noticeable on a floppy disk so he could take it back to the store and 
try it on some other pianos. Sure enough, he reported that while the 
other pianos like my model thump softly if you listen for it, they 
are not as loud as mine. He adjusted it as best as he can and said he 
would check with Yamaha for more ideas. This has been going on for 2 
years now, not just with the tump but also the solenoid clicks and 
double strike. I think the plan is to try a number of things to solve 
the problems, one at a time, progressing from the simple and 
inexpensive to the more complex and costly. This is a good
>  strategy but when it takes 6 months to go from one step to the 
next, that's a bit much. Like I said, he's very busy, backed up with 
work and I want to be patient with him, I was hoping someone in the 
group would have some ideas. Apparently, it's the first time my tech 
has encountered these problems and he's going through the learning 
curve. I was hoping I could help him accelerate the curve. I am 
fairly handy with mechanical and electronic things but have resisted 
getting my own hands on the works because I don't want to be blamed 
for anything going wrong while it is still being resolved under the 
warranty. One of the first things I would do would be to try putting 
felt on thumping pedal parts but when I suggested that to my tech, he 
was hesitant to do anything except step-by-step under explicit 
instructions from Yamaha. I would have no problem with that if it 
weren't for the fact that it's 6 months between visits.

and 3. With my Disklavier, whatever is on channel 1 goes to the 
piano, all other channels go to my stereo system which is plugged 
into the large phone jack on the back of the piano. When I get a midi 
that has one hand on channel 1 and another hand on channel 2, like a 
lot of stuff on perfessorbill.com I have to use Cakewalk to redirect 
tracks 2 and 3 to channel 1. Otherwise, I hear part of it coming from 
my stereo and part of it coming from the Yamaha acoustic piano. Do 
you mean I could have just gone into the setup menu of my controller 
and told it to send midi data on channels 2 and 3 to the acoustic 
piano instead of the speakers? What I had to do with Bill Edwards 
stuff (www.perfessorbill.com) to get it to play correctly was merge 
the 3 separate channels into one and delete the duplicate and 
triplicate pedal instructions and then reduce the
>  velocity. (I could have also left all 3 tracks and just reassigned 
track 2 and 3 to channel 1 and deleted all pedal information from 2 
of the three tracks)  Attached is a zip file with his original and my 
copy of his 12th Street Rag after I had to modify it to play 
correctly on my piano. You will see what I mean if you compare the 
files with Cakewalk or some other program that lets you get into it.
