Aldo Calpini has released version
a freeware VA type synth
built with SynthEdit.
FATMOO is a VST synthetizer, built with
it works on the Windows platform, and you need a VST
host to use it. aaand, VST is a trademark of
Steinberg Media Technologies GmbH.
it is basically a VA type synth, but
with some deliberately unusual features.
first of all, the oscillators (2
main + 6 LFO) have variable fatness. they can range
from square (approx) to sin (approx) to triangle to
"less than triangle" form. the knobs give visual
feedback about the current waveform.
second, all the usual parameters (OSC
B pitch, cutoff, resonance, etc.) as well as
oscillators fatness can be modulated with an LFO
and an envelope. there are 6 LFOs and 6 EGs
(envelope can also be inverted on parameters), you
can mix them as you like.
finally, OSC B can modulate OSC A's
fatness (sorta FM, but with a different meaning for
"F" :-). (well, actually, it sounds more like PWM
this is actually more or less a
"proof of concept", and it's my first experience
ever with SynthEdit and with sound design in
general. your mileage may vary, of course.
a few notes:
the synth is a little bit CPU
hungry, typical usage takes about 30% on my
Thinkpad (dual core Centrino @ 1.83GHz). it will
probably not work well on less-than-powerful
sound can get easily nasty and
distorted (and unharmonic) with modulation. use
the OSC B Pitch control is very
rude: it adds volts (in SynthEdit terms) to the
base pitch, so -1 is one octave lower, -2 two
octaves, etc. same goes with positive values. I
may replace it with something more sensible in a
future version, but for now take it as it is.
