Good feedback!
I'm not so concerned about beat matching with this thing as I am transitioning from multiple sections in a mix using Ableton. I'm more just wanting to have say a vocal/acoustic guitar verse slowly blend together and then (granularly) fade into a drumset/keyboard chorus or something like that. My aesthetic right now is very much one of "pop structure becomes abandoned into a chaotic transition into another pop structure." Rinse and repeat as you'd like.
Do you think this could be done in real time in an efficient fashion, using a kind of doubled up granular delay network?

Sounds good Kyle.
If you listen to old skool house DJs they often use the tone control to start with only the hi-hats/top of the mix (because that is where you get the best time acuity) then as the mix fades to the second part they drop in the bass.
For the mostpart only a few parameters will work for the grainsize and randomness without it sounding watery and blurred, an optimal window size and overlap.
The starting assumption is that you have two audio files and two phasors/line segments that give you a pair of timelines that are locked in beat sync.
The most obvious "granular mix" effect is to mix N grains from one side with 1-N grains from the other per unit time.
But the weight/density of the sound is a product of the number of grains per unit time and the grain size, so another mix would be to increase the size of one grain stream and reduce the other.
You could make another interesting effect by "dissolving" one stream into chaos by adding random time offsets to blur it out, and then quickly mixing the other one in with the same amount of blurring, then bring the new stream back into focus.
As far as tone/spectrum goes, smaller grains will generally be higher (because they must contain shorter periods) and longer grains will have more low frequencies.
Either way, you'll get modulation artifacts for grains whos period is less than 1/F if F is the lowest frequency in the mix, but I assume that is okay, just part of the effect.

Hello listers~
There's been a void of conversation on the list, so I thought I'd pitch my latest idea for a Pd tool: a granular cross-fader. I'm in the pre-planning phase right now, and would love to get some ideas/suggestions for how to implement this.
Basically what I'd like to have is similar to a DJ cross fader, but using granular methods to stochastically mix two (or more) signals using various common granular ideas (pitch shifting, time stretching, grain size, randomness parameters, overlap, etc.). This would make transitions much more exciting from a DJ end as well as when mixing two or more signals on a DAW.
What are your immediate thoughts/reactions to this?
