PLOGUE FUN

I got inspired to try a couple of things in plogue. These are more in the line of signal processing rather than composing_ but they do give rise to dramatic results !!!

My first idea was to break an incoming audio signal up into dynamic ranges, for each cycle that is. So different sections of the same cycle can be routed differently :)
I have really only tried this with bit and sample rate modification.



It does work well though !! Interesting results with sample rate, a lower rate for the lower thresholds, moving up to a higher rate for the higher..


The next, was to replicate a complex wave with a sine wave :)
The idea was to use zero crossings as points to determine the freq of the sine wave. This itself has been not particularly succesful - this may because Plogue does not do good maths :(

the idea is, when the wave crosses zero, the accum will split out the length of samples since last crossing - this gets converted into the freq of the lower oscillator.
The delay line is to make sure the freq's exist for appropriate lengths - this bit is wrong - needs more work !!

The next part of this one, is to get some sort of average amplitude for individual cycles.
