Transcript of Granular Engine Day 3

added file names to buffer~
added meter~
using scale
What We Have
What We Want To Add
Link Grain Length and Rate
Sample-rate Control
Synchronous Granular Synthesis
Why?
How?
Enables more accurate control.
More capabilities at our fingertips.
(line~, rand~, phasor~, wave~...)
Why?
How?
Now: Have to carefully set both Grain Rate & Grain Len to get a synchronous effect.
ex: Rate = 100 ms, Len = 400 ms
Len = Rate * #-of-generators
grains are sampled uniformly & continuously
vs. Asynchronous
grains are sampled stochastically
Have to do the math each time!
which layout rule is this breaking?
why 3.99? not 4?
Asynchronous Synthesis
"stochastic" control
What?
How?
Randomize a parameter within bounds
Q: rand~? noise~? pink~?
Q: which parameters?
Model 1
Model 2
set hi & low bounds
1. take a random signal between [-1.0, 1.0]
2. scale it to our new range.
set center & spread
1. take a random signal between [-1.0,1.0]
2. scale the spread (width) of the signal:
rand * spread
3. offset the signal by the 'center':
rand + center
