Re: 3 mysterious Disklavier problems (Pedal Thump Revisited)

2003-12-31 by fkagel

Walter,

Did you every get any resolution to your pedal thumping? Was it a 
mechanical adjustment that a you, the user, could do or will a 
technical pro be needed?

I assume the original MIDI e-competition files support the following, 
but don't know if your particular controller supports the same: 
Function | Piano Part | Rcv Ch = <change to HP>. HP is half or 
continuous pedal on Channel 3, with Left Hand on Channel 1 and Right 
Hand on Channel 2. Obviously, GM files out there in the wild do not 
abide by this DKV model, and thus the on/off (0/127) thumping!!!

A great filter utility would be to take out MIDI Controller 64 data 
from existing Piano Channel and move it to Channel 3. Anyone game or 
is this already avail? Manually this can be done with sequencing 
software.

It can't properly interpret half pedal or gentle pedal movement 
information like I find in the Piano e-Competiton midi files. You 
need one of the very expensive Pro models for gentle or half pedal 
movement. On mine (an ordinary consumer model Disklavier), the 
sustain pedal moves with a thump that can be heard all the way on the 
other side of the house. The noise is fairly easy to ignore most of 
the time because of the sound of a lot of notes playing at once but 
during quiet passages, the pedal thumping is very noticeable. At 
times when the pedal goes down while several notes are being held it 
sets all the strings to vibrating. I can only describe the noise that 
makes as a "low roar". I guess it is the closest thing to "white 
noise" that a piano can make.
