Welcome to the Rosci soundscape. Rosci is a digital VCO that
generates random waveforms to create unique, rich, and full
sounds. You are able to control how complex the sound is--add
harmonics and have a completely unique shape generate using
the generate button/trigger. BUT, it can also be tuned to
output basic waveforms (sine, square, sawtooth) if you so
desire.
TUNABLE PARAMETERS BREAKDOWN:
COMPLEXITY: Essentially a generation of unique timbre.
ROUNDNESS: Set the basic shape of your waveform. Go from from
sharp to soft sound, similar to filtering.
HARMONICS: Add up to 6 harmonies to your sound. The choir's
here.
FORMANTS: Accentuate certain overtones in your sound (like a
voice singing "ooo", "ahh", "eee").
DETUNE: Add a classic 'detune' with a changing phase wave for
extra wide sound.
HOW DOES IT WORK?
It is a pipeline of algorithms, which generates and modifies
a waveform starting from top to bottom. Rosci works on a
principle of key points: the generate button generates key
point location and amplitudes to be passed down the pipeline.
Tunable parameters:
Beginning with complexity, you set the number of key points
(even numbers only to create a waveform). Lowest complexity
sets two points, and highest complexity sets up to 20 points.
The number of key points will vary with each waveform
generated. From there, the roundness sets the type of
interpolation of the key points, from square to sine.
Adjusting the harmonics creates copies of the waveform and
adds them to the original waveform at double, triple, ... up
to 6x the base frequency. Formants maintains the frequency of
the wave, but squishes it so there is 'empty space' in
between (this is also called pulsar synthesis). Finally,
detune copies the waveform and 'detunes it' by increasing the
frequency ever so slightly. And there you have it: a unique
Rosci soundscape :)
