No, but... If you are sighted you can easily use a spectrum analyser. On Linux there is JAAA and JAPA for example:
http://kokkinizita.linuxaudio.org
Otherwise I'd be interested too in such a website.
In the appendix of the Csound manual, there are some "modal frequencies" for a couple of sounds. But no amplitudes are given. So I suspect more theory is required to actually make good use of those.
Sorry not to give a complete answer, but I hope it helps.

I have an example that uses GEN10 tables to imitate a range of acoustic instruments. Multiple tables are used for each instrument to cover a range of pitches and ftmorf is used to fill in the gaps.

http://www.iainmccurdy.org/CsoundRealtimeExamples/AdditiveSynthesis/ftmorph.csd

Each table covers the first 100 harmonic partials and were generated using a slightly automated process with this:

There's also a version for Cabbage:

Does anyone know of a resource online that outlines the approximate amplitudes of harmonics for different instruments?

Thanks for any help

Hi Iain.
Is there a shortcut to change instrument, provided in the above example?
Thanks.
Gabriel.

Steven, can you confirm that the blue and csd files are unusable as such
(the phase arguments of oscili are given in degrees whereas they are between
0 and 1 now) ?

The oscili parameter ranges were never changed. Phases were always normalised (0-1).

Hi Iain.
I can't use the mouse as I'm blind and, as I was able to listen to the 
sound just by pressing keys, I was hoping there were also some keys to 
change the active instrument.
Sorry if it is not, no matter.

Gabriel.

Hi Joel,

I think you're right.  I wrote the converter code a long time ago, and
from the date of the CSD file (August 7, 2001), I imagine I didn't
know what I was doing. :) I did find the original Java code I used at
[1], which might be useful as a start for a better program or script.
I wouldn't recommend using CSD or Blue file I had done these days.

Thank you for confirmation, Steven.
So basically in the java code

double degrees = Math.toDegrees(Double
                            .parseDouble((String) a.nextElement()));

should be replaced by 

double degrees = (1.0+Math.toDegrees(Double.parseDouble((String)
a.nextElement()))/180.0)/2.0;

First of all, ALL my gratitude to have spent your time in order to bring 
this new feature just for few people with so particular needs. Really, 
thank you.
I've redownloaded the script and it seems not working.
With the virtual keyboard focused, where the note keys work, the up and 
down arrows have no effect.
CSound 6.05, under Windows 7.

Under Mac OS I had an error on FLs components.

Does your script have a version number? I suspect my browser had taken 
it from the cache instead to redownload it again. How could I check in 
order to be sure it is up to date?
Bye.
Gabriel.

Hi Iain.
It works fine now!
Thank you very much.
