08 — DDL+LFO Delay Regen Range: -99 to +99
Controls the amount of regeneration applied to the delay time taps. The sign of the value
determines the polarity of the regen.
09 — DDL+LFO Delay Cross Regen Range: -99 to +99
Allows you to feedback the delayed signals to their opposite sides; the left voice crosses to the
right voice, and the right voice crosses to the left voice. A setting of +99 or -99 will cause infinite
repeats. Be careful, if the delay regen is set too high, it may cause this parameter to “blow up.”
Also, too high of a setting in parameters 08 and 09 will cause a DC offset, which will make this
algorithm shut down.
10 — DDL+LFO Regen Damping Range: 00 to 99
Adjusts the cut off of a low pass filter on the feedback signal, which controls the amount of
damping to the feedback signals. The higher the number, the more the signals are damped.
11 — DDL+LFO Right Delay Input Range: Off or On
Disables the input into the right side delay line. The right delay line will still get input from the
Cross Regen. This allows a ping-pong delay effect.
12 — DDL+LFO Right Output Level Range: 00 to 99
This parameter controls the right output signal level.
13 — Bass Fc Range: 0 to 1000 Hz
Sets the cutoff frequency of the lower frequency band shelving filter.
14 — Bass EQ Gain Range: -48 to +24 dB
This parameter sets the amount of boost or cut applied to the low shelving filter.
15 — Treble Fc Range: 01KHz to 16KHz
This parameter sets the cutoff frequency of the high shelving filter.
16 — Treble EQ Gain Range: -48 to +24 dB
This parameter sets the amount of boost or cut applied to the high shelving filter.
17 — EQ Input Level Trim Range: -24 to +00 dB
Allows you to adjust the input volume of the EQs to avoid clipping signals.
