Subject	[Csnd] question about modal frequency
	Dear community, I have a question about modal freqencies . If I use it with mode, e.g., can I do it in the following way? ; Dahina tabla [1, 2.89, 4.95, 6.99, 8.01, 9.02] areson1 mode ain, icps, ipcs2.89 areson2 mode ain, icps4.95, icps6.99 areson3 mode ain, icps8.01, icps*9.02

	Hi Stefan, That will work, but I don't think that the table of modal frequencies is supposed to be used this way. The ratios in Scott Lindroths' tables frequency ratio tables look like only center frequencies, not Q. So I'd interpreter the Dahina tabla as 6 mode resonators, not 3. The filter Q would then be something you would have to work with to find something you like I think. steven On Tue, May 25, 2010 at 4:07 AM, Stefan Thomas wrote: > Dear community, > I have a question about modal freqencies . > If I use it with mode, e.g., can I do it in the following way? > >> ; Dahina tabla [1, 2.89, 4.95, 6.99, 8.01, 9.02] >> areson1 mode ain, icps, ipcs2.89 >> areson2 mode ain, icps4.95, icps6.99 >> areson3 mode ain, icps8.01, icps*9.02 > > > Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"

That will not work correctly. You need to have a line for each of the modal frequencies like this:

; Dahina tabla [1, 2.89, 4.95, 6.99, 8.01, 9.02]
areson1 mode ain, icps, kQ1
areson2 mode ain, icps*2.8, kQ2
areson3 mode ain, icps*4.95, kQ3
areson4 mode ain, icps*6.99, kQ4
areson5 mode ain, icps*8.01, kQ5

The kQ argument at the end of each line defines the resonance bandwidth of each mode filter. You will need to play with these values to get the desired result.

Dear community,
I have a question about modal freqencies .
If I use it with mode, e.g., can I do it in the following way?

; Dahina tabla [1, 2.89, 4.95, 6.99, 8.01, 9.02]
areson1 mode ain, icps, ipcs*2.89
areson2 mode ain, icps*4.95, icps*6.99
areson3 mode ain, icps*8.01, icps*9.02

	About the mode demo -- fantastic! I am going to take a good hard look at the code and see how I can use these sounds in my pieces.
