Re: [disklavier] Re: Ideal Range for Velocity

2001-06-15 by Thomas N. Wheeler

Carol,

I do not believe there is any way to use veloset in dkv utilities to 
adjust the volume of ensemble parts only.  Adjustments in dkv apply to 
the overall spread of velocities of all instruments.  However, by 
importing a midi file into Cakewalk (or any other good sequencer) you 
can easily adjust the volumes of all parts using the volume (midi 
controller 7 value).  For midi files to be ultimately played on my 
disklavier, I use a setting of 90 or 100 for the piano parts and adjust 
the volumes of the ensemble parts to my satisfaction.  For example, I 
nearly always use a volume of 60 for the bass and drum parts for midi 
files played on my disklavier because my disklavier (a DC3 IIXG model) 
sits in the corner of our living room which is a relatively small room 
and rather bright sounding with hard walls.  I think that the speaker 
system to which your tone generator is attached matters greatly in 
setting the volumes of individual ensemble parts on the disklavier.  For 
example, I have a Rush speaker mounted under the sound board of my 
disklavier.  The Rush is an outstanding speaker and really produces 
prodigious amounts of very nice sounding bass.  I actually installed an 
equalizer between my disklavier's tone generator output and the Rush 
speaker to control the 62 kH bass and tone it down a bit.  Again, this 
was no doubt necessary because of the corner placement of the disklavier 
and  acoustics of my living room. 

I nearly always listen to my disklavier at the lowest volume setting 
(-10 dB).  I don't find any mushiness in the keys when I play and I play 
my disklavier now more than I listen to software on it.  However, I 
should also quickly add that I am a very inexperienced pianist and my 
sensitivity to the touch of the disklavier's keys may not be as well 
developed as yours. 

I have Power Tracks 7.0, but I have not used it very much.  I'll look 
into whether it has the ability to tone down the  overall volume level 
of a musical selection without interfering with the balance between 
tracks. 

The real difficulty in adjusting the relative balance of ensemble and 
piano parts comes from the fact that midi files sound quite different 
when played on my disklavier than when played back on my computer's 
sound card.  I have taken two steps to address this problem.  One is to 
attach a lap top computer to my disklavier's To Host port and do the 
final balancing of midi files directly at the disklavier so I can adjust 
both piano velocities and ensemble volumes to my satisfaction for my 
piano and my living room.  Another step that I have taken involves the 
main computer in the rear of my home where I do most of my midi work.  I 
have recently (after six months of trying) been able to purchase a 
Yamaha MU15 portable XG tone generator which I have now attached to this 
computer.  I find that this XG tone generator is far superior to the 
tone generator in my Creative Live Sound Card and makes it easier to get 
the ensemble instrument volumes more in balance with the piano parts 
before I go to the disklavier with the file.  Of course it is still not 
the same as listening to the file on the disklavier, but it is one step 
closer. Finally, I have equipped the lap top computer setting on my 
disklavier with an ethernet wireless networking link to the computer in 
the rear of our house.  This works superbly and allows me to carry out 
the high speed transfer of files at will between the two computers.
