Basic Sound Parameters

SBF2 (SideBand Filter 2)
Similar to
SBF1
, but with stronger resonance.
COMB (Comb Filter)
Comb filters in general use several delay lines to boost or attenuate a series of frequencies. The filter frequencies in the
V-Synth
version
follow the harmonic series, so it can be used as a static effect to isolate or remove noise or to boost/attenuate partials within a waveform:
Removing / isolating the noise component of waves
Start from
512:INIT PATCH
, select
PCM
for oscillator 1 and change the waveform to
086
:
F Ahs Mid
. Go to
COSM1
, select
COMB
, change the Octave to
0
(zero)
and
Tone
to
64
(the Thru position). Turn the
P1
knob (which controls Tone) in the
COSM1
panel all the way down to isolate the noise component. Turn it up to remove
the noise i.e. all the inharmonic partials!

Adding / subtracting partials
Start from
512:INIT PATCH
, select
ANALOG
for oscillator 1 and change the waveform to
SAW
. Go to
COSM1
, select
COMB
, change the
Octave
to
+1
and
Tone
to
64
(thru)
. Turn the
P1
knob in the
COSM1
panel all the way down to remove all the even-numbered
partials. The sound of the oscillator will now be very similar to
HQ-SQR
(which only contains
odd-numbered partials). Now try turning the
P1
knob up - even-numbered partials are
emphasized and the sound, though very similar to the original wave (sawtooth) is now an
octave higher.
Of course the
Tone
parameter can be controlled in the Matrix (via the
CSM1-PRM1
parameter). See “
The Matrix - Assigning Destinations
” below.
