Ken, Ian and Other Disklavier Owners Who May Respond,

Thank you for your expressions of support. 

Yamaha in the U.S. and Bill Brandom in particular, have always been very 
supportive of the disklavier product line.  The Mark IV is my third 
disklavier.  I first purchased a DC3IIXG (Mark II model), then traded 
that a few years later for a DC3A (Mark III model), and in November of 
2004 I purchased the DC3M4t (Mark IV) model that I now have. As others 
have expressed, part of my reason for purchasing the Mark IV was the 
promise that the Mark IV would soon be upgraded with features that it 
did not have when introduced.  I remember being expressly assured in a 
personal phone from by the National Sales Manager for the disklavier 
product line (not Bill Brandom, incidentally) that the Mark IV would 
soon be able to access the internet and download music files.  That was 
in late November 2004 when the Mark IV was introduced! 

I use virtually every single feature on my Mark IV since I began taking 
weekly piano lessons when I retired a litle over five years ago, and I 
have the good fortune of having a wonderful young pianist classically 
trained in Moscow, Edinburgh, London, and the University of Minnesota 
who comes each week to my home, gives me a 1-2 hr lesson and records 
every single one of my assignments on my Mark IV.  When version 1.20 
came out in late August, I was very pleased to find that overdub 
recording had been enabled.  This allows my teacher to record both 
parts  of duets intended for four hands.  I then turn off the primo part 
and play along with my teacher playing the secundo part.  This is a 
wonderful learning technique.  Add to that the ability to set playback 
to begin from any section of a piece and end at any section and either 
loop the playback or simply go back to point A and await the start play 
button to be pressed, and you have some powerful tools for using the 
Mark IV as a teaching/learning instrument. 

I love my Mark IV.  My frustration with Yamaha Japan is that they are 
either very slow to listen to customers in their largest market (the 
U.S.) or don't listen at all and do whatever they please.  The potential 
in the Mark IV for both entertainment and teaching has scarcely begun to 
be recognized by Yamaha Japan.  This is especially difficult to 
understand and swallow when you look at the very very high cost of the 
Mark IV instruments.  I do continue to recommend the disklavier to 
fellow students and to teachers with whom I speak from time to time.  It 
is a fantastic teaching instrument and a delightful piano to play and be 
entertained by. I do, however, also point out that it is a mistake to 
buy the disklavier in anticipation of future enhancements to the 
software.  Buy it for what it has today, or don't buy it, but don't make 
your purchase decision on this expensive an instrument based on features 
that may or may not ever appear.

RE: [disklavier] Re: feedback to Yamaha

2006-11-09 by Dan O'Connor

Dear All:
 
In my opinion, almost every request or challenge that people seem to
have with the Disklavier can be solved by moving to the PC environment.

 
There is no real flaw in the design in my view.  Not everyone is PC
literate so Yamaha tries to build the best stand-alone system they can.
If you can move to the PC world everything becomes state of the art.  
 
All my files are on the PC, wirelessly connected to the internet,
VanBasco for Karaoke, Yamplayer (thank you Dan C. ) for musicsoft,
Cakewalk for midi, I have no interest in Smart recordings etc.  Yamaha
has updated mid-90's technology to allow my older wagon model to do
almost everything that the Mark IV does with the DSR1 and CD upgrades (
I did not buy the CD player). 
.  
 
Japanese companies don't always have the best marketing, but my 15 year
old system works flawlessly, sounds great, holds a tuning, and is more
than I could have hoped.  With a strong users group I can convert my
floppies to computer files, play PianoDisc as well, and have collected
some 14 thousand midi files.  
 
I would recommend a Yamaha piano and Disklavier to anyone.  It works and
it works well.  
 
Thought I would express a word of support for the hard working folks at
Yamaha.  Besides can it be too far off before Elton John comes to play
in my home?
 
Cheers
 
Dan O'Connor

	Subject: Re: [disklavier] Re: feedback to yamaha

	 

	Bill,
	
	It is good to see your response to Jason, and I am sure that all
of us on this forum appreciate your participation and for your listening
and forwarding our ideas to the engineers in Japan who do the
programming for the Mark IV.  
	
	I would like to suggest a few ideas, some of which I have been
requesting for over two years now.  
	
	(1) A search function.  The necessity for this is readily
appreciated by anyone who has a large number of files on their
disklavier and tries to find a particular song or artist.  Right now it
is  impossible to do so.  
	
	(2) A larger internal HD drive for the Mark IV.  Initially an 80
GB internal HD for the Mark IV seems like a lot of drive space, and it
is if one is only storing midi files on the HD.  However, the Mark IV
stores CD's (required for PianoSoft Plus Audio and Smart Piano Yamaha
software) as ..wav files.  These take up a huge amount of space, and it
is easily possible to consume all of the capacity of the Mark IV's 80 GB
HD when one begins storing CD's on the internal HD.  In fact, I have
already done so, and because my internal HD on my Mark IV has very
little free space remaining, I no longer purchase Yamaha software since
I have no where to store it.  Please note that it is NOT possible to use
an external USB HD to store any of the Yamaha software that requires
CD's due to copy protection issues and thus one has no choice but to use
the internal HD of the Mark IV.  The Mark IV is modular in construction
and replacing the internal HD of the Mark IV with a larger Yamaha
approved HD should be possible.  I would strongly urge Yamaha to make a
larger HD available for the Mark IV.  
	
	(3) Enable the Yamaha TRC-100 tablet remote to connect
wirelessly to the Internet and download files directly to either the
Mark IV's internal HD or (if the files are not copy protected) to an
external USB HD.  It is illogical that we have a fine wirelessly
controlled disklavier and absolutely no way to interact with the
internet from the Mark IV to download files.  This feature is long
overdue!  
	
	(4) Since purchasing the Mark IV, I have found the tablet remote
(the TRC-100) to be of little or no use.  In fact, the pocket remote
(PRC-100) has many capabilities that the larger TRC-100 does not have.
I would urge Yamaha to provide software that makes full use of the
capabilities of the TRC-100.  This would not only include wireless
access to the Internet for midi file downloading, but other features as
well.  One perfect example would be Yamaha's own Digital Music Notebook
software.  This software, running on the TRC-100 remote, would allow a
vast range of teaching/student interactions not now possible on the Mark
IV.  I am sure there are many other examples of software that could run
on the TRC-100 that I am not aware of that others might suggest.  
	
	I will close by pointing out several of the features I am
requesting for the Mark IV are already available on some Yamaha
clavinovas which are able to wirelessly download software from the
Internet.  The Mark IV is a VERY expensive Yamaha instrument.  The Mark
IV should represent the pinnacle of what Yamaha is able to do with their
instruments.  Many of us purchased the Mark IV expecting features to be
added at regular intervals.  While this has occurred to a small extent
with the version 1.20 software, I have been disappointed in how slow
Yamaha Japan has been to enable features clearly supported by the basic
hardware of the Mark IV.  
	
	I hope that if others share my interest in any of the above
features (and others that I have not mentioned) they will add their
voice to my own pleas for these features.
	
	Tom Wheeler

Is it possible to play smart recordings on your PC as well and just send the midi out to the disklavier? Also, what about the extended midi signals used by the Mark IV? Does anyone know if there are software midi players out there that support the extended midi format? Speaking of which, I was thinking the other day it would be cool to do midi over IP, to be able to teach or take lessons remotely. Is there software that does this already? I don't think it would be too hard to do.

There is software to do MIDI over IP already, but there are some issues

I wasn't aware the MkIV used extended midi signals, just extensions in

higher bandwidth than you can over a 31.25kbps midi link).

The ones I've got bookmarked are below, but I've seen others too. open 
muse appears to be the most mature, but I've probably missed loads. It's 
been a while since I looked at this idea too, so I've probably missed 
developments.

http://portal.acm.org/citation.cfm?id=1089092


One of the interesting ideas I saw was the MIDI XML format. I think it 
should be possible to set up a MIDI XML stream between two devices, 
assuming you don't mind a small buffer / delay to cope with timing 
adjustments and don't intend running over a slow link (in which case you 
would need a large buffer). Unless you are trying to play something 
together with another player, live, over a network these issues probably 
do not matter - neg the Claviers has a 500ms delay in it anyway and it 
doesn't matter for most playback, recording etc paps (if you disable 
this then it makes a right mess of the dynamics etc as it is unable to 
fire the keys well enough in advance to get soft notes).

Using a UNIX system, one could easily stream MIDI from devices over an 
SSH tunnel or network pipe, effectively doing IP over midi, but it isn't 
really something that is practical for most applications.

I believe that Steinberg VSTLink effectively allows IP over MIDI, by 
running virtual synths on headless boxes for use in studios (ie you put 
the server in a rack outside your studio, and just run audio cables to it).

If I find more I'll post them to a wiki page.

Regards

James

Re: [disklavier] Re: feedback to Yamaha

I think John Q. Walker said earlier when he went to look at some early Mark IVs that they had a much more sensitive method of measuring velocity and playing it back, especially on soft passages. I think he also said that they used 16-bit values for velocity. I am surprised to hear that this is not the case. John, is my memory mistaken?

Carl, I'm afraid there may be some inaccurate statements in the above.

I've attached a document Yamaha provided through the DUG a few years ago
which explains the basics of the Disklavier Pro's XP format.  I'm not sure
whether non-Pro Mark IVs support XP playback or not.

A standard MIDI stream supports 7-bit velocity levels ("off" + 127 levels
of "on").  While it's true that MIDI involves 8-bit bytes, the highest bit
is used to distinguish command bytes from parameter values; that's why you
don't get 256 velocity levels.

XP is basically a backwards-compatible extension to MIDI that adds the
transmission of 3 additional velocity bits in a separate message preceding
the actual note message.  The note message carries the most significant 7
bits, resulting in correct playback even on MIDI equipment that doesn't
support the XP extensions.  XP-enabled equipment will watch for the
messages providing the additional 3 bits of velocity data and use it in
conjunction with the 7 bits provided through the normal note on/off
messages.  Thus, XP provides up to 10 bits of velocity levels ("off" +
1023 levels of "on").  Equipment that does not support XP will simply 
ignore the extra messages.

In the attached document, Yamaha acknowledges that while the extra 3 bits
do enhance the playback accuracy considerably, in practice, the Disklavier
can accurately reproduce only between 8 and 9 bits of resolution
(somewhere between 256 and 512 expression levels).

Achieving 65536 consistently reproducible levels in a reproducing piano is
both mechanically impossible and musically unnecessary.

Thanks for the clarification Mark, but I disagree with your last  
statement:

I think the feat would definitely be mechanically possible, but your  
point about how musically necessary it is may be valid.  However,  
there may be people aurally astute enough to distinguish between more  
than 1000 velocity levels.  If this is humanly possible, then I think  
one could argue that there would be benefit in increasing the  
sensitivity level.  But I agree that it is not extremely important.

Carl

Re: [disklavier] Re: feedback to Yamaha

2006-11-13 by George F. Litterst

Carl,

There are 2 issues:

--the ability of a particular Disklavier to record and playback.

--the data used to store the recorded performance

The Mark IV has improved sensors and, especially, improved playback  
solenoids. That means that it can do a better job of playing back the  
data that has been given to it.

So, a Mark IV can play loud passages louder and software passages  
softer than previous non-Pro Disklaviers. However, it does not  
generate the extra bits of data that the Pro does during recording  
and it does not respond to the extra bits of Pro data (called XP data).

The record and playback of the standard Mark IV is extraordinary.  
Most people would not notice the difference between it and a Pro.  
However, it is true that the Pro offers greater resolution during the  
recording and better playback.

PianoBench

I'm sticking to the "mechanically impossible" statement, adding the
reasonable assumptions that the piano is not in a vacuum and uses a
standard grand escapement action, which just wasn't designed to achieve
this level of precision.

Yamaha's own admission that they can control the solenoids with 1024
levels but realistically get only around 256 distinguishable levels
already leads one to extrapolate that achieving beyond ten bits of
playback resolution is unlikely... adding more input bits isn't the answer
to overcoming mechanical limitations.

PianoDisc mentioned at the 2006 NAMM show that they have a high-res
playback system in development, and it uses ten bit expression levels.

Wayne Stahnke's Boesendorfer SE system is ten-bit.

Boesendorfer's new CEUS system is ten-bit too.

Ten bits appears to be the practical upper limit for this application.

Regarding the amplitude resolution of human hearing, these links are
interesting (though more casual than scientific):

Re: [disklavier] Re: feedback to Yamaha

While varying levels of dynamics are important, I think far more 
important than increasing the number of levels is the timing accuracy. 
As mark says, the action wasn't designed with this application in mind, 
and I find it hard to believe that

Studies have been done that show playback accuracy of player pianos is 
not as good as you would hope - there was a paper somewhere (possibly in 
the archives?) which compared a mark II disklavier to at least one other 
system and found that there were great timing inaccuracies when the 
velocity was varied. Given how important small timing changes are in 
other areas of audio, I wouldn't mind betting that it makes quite a 
difference with pianos too. It would be interesting to see how the Mark 
IV compares to previous versions of the disklavier.

Re: [disklavier] Re: feedback to Yamaha

2006-11-14 by George F. Litterst

Good evening, everyone.

I believe that the emails below are long on rumor and short on fact.  
I would love to read document in which Yamaha states that "that they  
can control the solenoids with 1024 levels but realistically get only  
around 256 distinguishable levels" or the studies that "have been  
done that show playback accuracy of player pianos is not as good as  
you would hope."

The Mark IV Pro has an extraordinary record and playback system.  
Based on the reactions of the various Piano-e-Competition juries that  
I have observed--which include musicians of the highest calibre, I  
believe that the instrument has a practical resolution that exceeds  
what the average listener can perceive and that it is at least  
adequate--if not more that adequate--for the most discerning musical  
ears.

As a pianist, I also believe that the Mark IV Pro can outplay a  
human--meaning that it can play faster, softer, and more even that a  
human.

When making judgments about any particular piano, it is important to  
make sure that the instrument is in excellent regulation and is  
properly calibrated. If you are sending it MIDI data from an external  
source via a MIDI cable, it is important for it to be set to Delay In.

Re: [disklavier] Re: feedback to Yamaha

Hi PianoBench,

I thought I was quite clear in my email that the study referred to 
MarkII pianos, and that I felt it would be interesting to see how the 
MarkIV compared in a similar test. I wouldn't be surprised if it was 
much better, but still had timing inaccuracies over different 
velocities. Playing through the standard piano action isn't going to 
make life easy imo.

For the most part, my MarkIIXG exceeds my expectations on replay, so I'm 
happy. What I would like is the ability to play softer (but thats the

There are variations of the paper that were presented to different 
audiences, but I haven't seen any later studies.

Dr. Werner Goebl authored a follow-up paper under a slightly different title and updated some information.

The first paper titled, \u201cAre computer-controlled pianos a reliable tool in music performance research?\u201d was referenced below by James Fry and was submitted at the Workshop on current research directions in computer music, November 15--17, 2001.

The next paper was submitted to the Journal of the Acoustical Society of America in 2003 and was titled \u201cMeasurement and reproduction accuracy of computer-controlled grand pianos\u201d

http://www.ofai.at/cgi-bin/get-tr?paper=oefai-tr-2003-16.pdf

Both articles used a Disklavier Mark II. At the end of the article Dr. Goebl writes:

The Disklavier measured in this study is certainly not the top

model produced of the Yamaha corporation. Since then, Yamaha

issued the Mark III series and the high end series, called \u2018Pro\u2019

(e.g., the special \u2018Pro2000 Disklavier\u2019). The latter series uses an

extended MIDI format (with a velocity representation using more

than 7 bits), and additional measures like key release velocity to

reproduce the way the pianist released a particular key. It can be

expected that these newer devices perform significantly better than

the tested Mark II grand piano.

I have still yet to locate a comparable study using a Disklavier Pro.

Interestingly enough, Dr. Goebl was referenced in a June 5, 2005 New York Times article titled, \u201cPlay It Again, Vladimir (via Computer)\u201d where he was asked his opinion about the work of Dr. John Q. Walker, the president of Zenph Studios. Zenph Studios take audio recordings of live music and convert that information into a file that can subsequently be played back on a piano as if it was live.
