A few VCV Rack modules building off of Xenakis's stochastic synthesis and GENDYN program.

A stochastic synthesis generator. Grandy implements an extended version of Xenakis's Dynamic Stochastic Synthesis coined Granular Dynamic Stochastic Synthesis due to the added synchronous granular synthesis twist. All knob controls can be controlled by +/-5 CV.

bpts -> vary the number of breakpoints used in the synthesis
astp -> maximum step that a breakpoint's amplitude value can take
dstp -> maximum step that a breakpoint's duration value can take
pdst -> change the probability distribution used to generate all step values. l - LINEAR, c - CAUCHY, a - ARCSIN
mirr -> toggle between the wrapping and mirroring of breakpoints if they surpass amplitude or duration bounds

gfreq -> control frequency of the sin wave that is granulated if in sine wave mode

fcar -> frequency of the carrier wave
fmod -> frequency of the modulating wave
imod -> index of modulation

A module for stochastic concatenation. Controls for four seperate GRANDY oscillators on the left and global controls on the right.

f -> oscillator frequency
b -> number of breakpoints
a -> maximum amplitude step
d -> maximum duration step
stutter -> number of cycles to output

All global controls are -1 - +1 and affect all oscillators.

A module for stochastic 'decomposition' ... make of it what you will

l -> length of sample
i -> input for sample signal
g -> on gate will sample incoming signal to i
acc -> toggle breakpoint accumulation
mirr -> same as for GRANDY
pdst -> same as for GRANDY
bpts -> affect spacing between breakpoints / number of breakpoints
astp -> same as GRANDY
dstp -> same as GRANDY
env -> same as GRANDY
