to find 'best match' splice points to minimize their audibility.
1. PITCH (-1200 to +1200 CENTS): Varies the amount of pitch shift in 20
cent increments. -1200 cents is one octave down, +1200 cents is one
octave up, and each 100 cents is one semitone. This parameter can
mapped to the expression pedal for real-time foot controlled pitch
bending, as in the "WHAM ME" preset.
2. DETUNE (-25 to +25 CENTS): Varies the amount of pitch shift in 1
cent increments to achieve a slight detune effect. The total pitch shift
will be the addition of the PITCH and DETUNE values, but typically
PITCH will be set to 0 if DETUNE is being used.
3. PSHIFT MIX (0 to 100): Controls the relative mix between the original
signal and the pitch shifted voice.
4. PSHIFT PAN (0 to 100): Pans the pitch shifted voice. 0 is fully Left,
100 is fully Right, and 50 is centered.
5. DIRECT PAN (0 to 100): Pans the direct voice. This is a repeat of the
same parameter from the Mixer Function. It is repeated here for
convenience.
K) FLANGE Function
The flanger works in a very similar fashion to the chorus, except the
variable delay time is much shorter, resulting in the predominate effect
being a modulated comb filter, not a pitch bend. It is therefore similar
sounding to the phaser, but since it uses time delay the resulting phase
shift is linear with frequency, whereas the all-pass filters used in the
phaser are not. The result is that the notch frequencies in the flanger
have a different spacing, and there are many more of them. There are
also two voices in the flanger. These are panned hard left for voice 1 and
hard right for voice 2, removing the need for Level and Pan parameters.
Using Phase and Flange at the same time may be worth a try.
1. FLANGE (OFF or ON): Controlled via VALUE knob or the MOD
switch. For footswitch control, the MOD SWITCH: function must be
set to FLANGER.
2. FLA REGEN (OFF to 2 dB): Controls the amount of feedback
within the flanger. This affects the shape of the notches or ‘teeth’ of
the comb filter, and also the time-domain decay of the response,
resulting in a more dramatic effect. But as in real life, you can get
tired of too much ‘drama’.
3. FLA DEPTH 1 (0 to 100): Varies the amount of change in the delay
time, which varies the amount of change in frequency of the
notches in Voice 1.
4. FLA RATE 1 (1 to 127): Varies the rate at which the notch
frequencies are being modulated. The rate can also be controlled
by pressing 2
nd
, then pressing twice (tapping) on the TAP switch, if
