DESCRIPTION:
spectral arpagiator using Victor Lazzarini's pvsarp.
It arpeggiates the spectral components of a signal
CONTROLLERS:
ON/OFF - bypass
arp left/right - target bin, normalised (0Hz - Nyquist)
overlap - The distance in samples (“hop size”) between overlapping analysis frames
size - The FFT size in samples
wet/dry - mix direct signal with effect
modulation freq - modulation frequency
modulation depth - modulation depth/gain
modulation left/right - phase of left/right modulation
modulation shape - draw shape of modulation
modulation draw/bell - choose preset 'bell' or draw freely
modulation random - depth of jitter
mod. min/max - set boudaries to random modulation
---
