Spectral Music Workflow

Hello,
This is my first post here so I'm happy to have found this group!
I'm starting to explore some spectral music concepts, mainly the spectral (FFT) analysis of sounds to generate pitch sets for a piece of music. I'm trying to figure out the best workflow for this. I've completed one piece in this style already but my workflow was rather cumbersome. My new idea is to try to explore soft-synths that allow Scala tuning file imports.
But while learning Scala I've run into a bit of a conundrum. The FFT analysis of a sound will give me a list for the partials for a sound. This is not really a scale per-se, but a list of frequencies. Scala seems made more for building a set of scales that repeat at x-number of notes, but can it also be used to generate a set of frequencies for every note of the scale? In other words a low D might be 23 cents sharp but a D a few octaves up might be 250 cents flat, so I would need to define all of the notes on the keyboard in this way.
I believe that you can make a scale in Scala any arbitrary size, so could I theoretically make one that is 88 keys wide and define each note? I believe so but I'm not sure exactly how to go about this. I'd love any insights into using Scala for this approach and also if there's a better tool or idea out there please let me know!
I'm not sure if this board has dealt much with spectral music but I'm pretty sure there are some Scala experts amongst you.
Thanks so much,
Ben

Hi, and a late welcome! :)

I don't have much experience with custom periods or non-periodic scales in scala, but afaIk scala always uses the last interval as a period. So if you have an 88-note scale, you can specify all notes as intervals (except 1/1, which is always assumed and should be omitted). The last interval will serve as a period, but you can just define the 87 notes that are not 1/1, and ignore everything beyond, pretending the scale is non-periodic.

P.S.: As you probably noticed, these yahoo message boards aren't very active anymore. I think most people (not including me) are on facebook, so if you're looking for a more active community, you can give it a try. A list of facebook groups (and other useful links) can be found here: http://xenharmonic.wikispaces.com/GeneralDiscussion http://xenharmonic.wikispaces.com/GeneralDiscussion (scroll down a little)

P.P.S.: Tuning a D 250 cents flat sounds a bit extreme. Oo
