one click clockwise, then using the PARAM knob to select the parameter
to adjust.
A chorus works by running the signal through a short delay of about 20
ms, and mixing the delayed signal with the original. The delay time is
modulated according to the rate and depth, creating a small amount of
pitch bend in the delayed signal. The BETA DSP has 4 voices, each
separately delayed, modulated, and panned left or right, providing a lush
stereo output. Parameters 3-12 below only apply to the CRS function.
1. CRS/PSHIFT (OFF or ON): Controlled via VALUE knob or the
MOD switch. For footswitch control, the MOD SWITCH: function
must be set to CHORUS.
2. CRS MODE (CRS or PSHIFT): switches between the modes.
3. CHORUS MIX (0 to 100): Controls the relative mix between the
original signal and all 4 delayed voices.
4. CRS DEPTH 1 (0 to 100): Varies the amount of change in the
delay time, which varies the amount of pitch bend in Voice 1.
5. CRS RATE 1 (1 to 127): Varies the rate at which the pitch is
being modulated. The rate can also be controlled by pressing 2
nd
,
then pressing twice (tapping) on the TAP switch, if the MOD
SWITCH: function is set to CHORUS and the chorus is on and
delay is off, or the MOD switch is the last one used.
6. CRS LEVEL 1 (OFF to 0 dB): Controls the level of voice 1 that is
mixed in the stereo output.
7. CRS PAN 1 (0 to 100): Pans voice 1. 0 is fully Left, 100 is fully
Right, and 50 is centered.
8. CRS DEPTH 2 (0 to 100): Same as for voice 1.
9. CRS RATE 2/1 (0.1 to 1.5): Sets the ratio between the rate of
voice 2 and the rate of voice 1. It is done this way so that if the
rate of voice 1 is varied by either the VALUE knob, the TAP
function, or the EXP. PEDAL function, the rate of all 4 voices will
track each other. Typically these ratios are set to a value other
than 1.0, so that each voice will modulate at a different rate
resulting in a more random and ‘lush’ sounding effect.
10. CRS LEVEL 2 (OFF to 0 dB): Same as for voice 1.
11. CRS PAN 2 (0 to 100): Same as for voice 1.
12. The explaination for voices 3 and 4 are the same as for voice 2.
A pitch shifter works by storing the signal in a short delay, then reading it
out at a faster (shift up) or slower rate (shift down). For a shift up, this means
that portions of the signal must be repeated. For a shift down, portions of the
signal are thrown away. For either case, the output signal will be spliced
together from portions of the input. The BETA DSP has an intelligent algorithm
