i want to create a Kyma sound where i can apply panning effects to only the high frequency of a sound file on my HD.

what is the best way, in kyma, to have a Generic Source and then divide the frequencies, so one path can go along to various effects while the other path goes to the output uneffected.

of course, the frequency division could hopefully be variable (so i wouldn't have to just do high frequencies, for example) and also the effect after the division is of course variable (wouldn't have to be panning.. but could be a filter, a granulator, etc)

i'm really interested in such frequency-band specific processing of complex samples...

is this possible in Kyma without using and FFT/live analysis... as that changes the sound so much... i would ilke to keep my original source simply the disc file, not an analyzed aproximation.

thanks..... in advance!

hope i do it right...

freqDivider.kym

attached is what i've come up with based on your suggestion. the high frequency chain is running through a chopper and a panner. and i've used a generic beat from the kyma sample library as an example.

my question is... can i have one single slider that controls the point of cutoff between the two filters (low pass/high pass).. so, if the slider is set to "3000 hz" that means everything above 3000 is going thru my high chain and being processed and everything below 3000 is passing straight to the mixer unprocessed.

thanks..

and again, sorry if this is simple... i am forever a novice.

ps: does the patch look ok to you? anything i did "wrong" ?

taylor,

you can assign an !value into multiple fields, so i'd put something like !crossover in all your filter cuts to have one parameter control the crossover value.

in looking at your sound, the only 'wrong' thing is that you have a stereo processing of the high freq (L, R compressors into filters) running into a mono sound, the chopper. if you want the chopper to be applied on the independant stereo sides, move the chopper after the filter and before the channel joiner and then the panner will pan the stereo signal. the chopper hot parameters can mirror each other or not, depending on preference.

thanks! this is exactly the kind of help i was looking for... watching out for stuff like this, running a stereo signal into a mono prototype... yeah, i'll fix that.

as far as the frequency crossover slider goes, i should have been more specific.. yes, i (think i) understand how to make the slider.. simply type, for example, "!Crossover" into the frequency field of all 4 filters...

but, what i want to know how to do is make that slider read and control FREQUENCIES.. not be a "generic" 0-1 control.. but something that actually will read "3000" or "5000" (meaning, hz)

do i simply scale it in the VCS to be 20-20000 (again, meaning hz) ?

i doubt it... or, maybe it is that easy.. maybe kyma knows that a control pasted into the frequency file is supposed to control frequency... (does that make sense?)

i hope i'm making sense here.. but i think you get the idea of what i'm trying to do..

thanks!

!crossover hz

then scale your vcs to 20 - 20000.

this is indeed one of the coolest features in kyma language. just add an "hz" or "nn" or any of the other possibilities somewhere described in the manual. sorry to be not specific enough...

kyma generally knows to look for certain values in a field. so for freq fields it expects hz values by default. if you want it to be nn or 0-1 or even time relative, you have use qualify the value like the other poster detailed.
