Sounds promising. Personally, I have lots of comment and question about the K5000
- I just haven't had the time to really delve into these matters for real yet.
About .WAV files, there is a piano sample on "The Chronicles of Heaven" labeled
"Piano - Source: Roland SC-55". This is a clean and good sample, which
plays back well as .WAV file. But SoundDiver is not able to convert it into
K5000 format successfully. If anyone has managed to get a good patch out of this
one, with or without extra editing, I'd like to hear about it.
Another way to create piano sound is to choose the "piano" alternatives for
harmonic level and envelope in SoundDiver. This results in a sound that actually
resembles a real piano, but it is rather feeble. I am sure that a *much* better
piano sound can be made on the K5000, the question is just *how*...?

I don't think the Wav import function in Sound Diver was really meant to convert
wav files into K5000 patches. I think it was intended more for creating new
sets of harmonics.
If you could get a spectrum analysis of a piano, you could try to model all of
the various frequencies (using up to 24 sources with harmonics from different
fundamentals). Then you probably have to use one of the PCM sounds to
effectively emulate the plunk of the hammer on the strings.
Like someone pointed out earlier, a piano has a good number of overtones that
aren't in the harmonic series, and I don't think you could create a decent piano
patch without taking that into account. That said, does anyone know how to figure
out just what some of those frequencies are???

Great to see that you've tried to use the samples i've sampled from one of my
synths. I've sampled the piano to give you the possiblility to create an additative
source which is build of harmonics in that additative source. I didn't use it
myself but i thought i could give it a try. I've created a new patch called AccPiano.
It's on my homepage. I've used the sample to create this patch.
It turned out that especially in the middle and higher level of harmonics the
conversion of the sample is not that great. I think that you can create a good piano
patch though. You can use this patch and add 2 additative sources. One source must
be played only for the lower velocity range. This source must an
additative source of the lower and middle harmonics of the piano sample.
The second source must be played only for the higher velocity range. Use strong
middle harmonics and a bit of high harmonics in this additative source. This
could do the job i think. Maybe it's an idea to use the piano-sample as our first
project to program a good piano patch to see if it can be done!! Kenji, I think
it's a good idea to create a section to build samples based on wav files. If you
want you can put the sample and accpiano patch on your page to start this
project .

KS to Gain once again

Experimenting with a piano sound, I just could not understand why the tone was
so mellow. After careful comparison with other sources I finally found the
culprit: KS to Gain in the DHL Common screen was set to +45. Reducing it to 0
or some negative value cleared up the sound and brought back the high
harmonics.
This has been mentioned before, but some explanation for things like these is on
the very TOP of the wishlist as far as I am concerned. Is there anything in the
words "KS to Gain" to tell any of you that this is really a brightness control?
Whether or not this is a bug is not my prime concern. What I want is DOCUMENTATION
so that I don't have to waste time on things like that.
Besides info on "hidden features" like this one, we sorely need some documentation
on the finer details of rates and levels. It is probably too late to ask for
times instead of rates, but if there is some free program memory left for extra
features, I wish Kawai would let us have parallel screens with times (possibly
logaritmic ones) in them.
