06 — Vibrato Sample & Hold Rate Range: Off, 001 to 100
Controls the sample rate of a sample and hold network. This is applied to the LFO within the
vibrato. When in hold (low values), it causes rhythmic chirps in the pitch of the audio signal.
Higher values will increase the number of holds per second, making the vibrato flow more
smoothly. The sample and hold function can also be turned Off.
07 — Vibrato Left Delay Time Range: 0 to 1500 ms
Controls the time delay on the left regenerated delay.
08 — Vibrato Right Delay Time Range: 0 to 1500 ms
Controls the time delay on the right non-regenerated delay.
09 — Vibrato Delay Regen Range: -99 to +99
Controls the amount of positive or negative feedback applied to the regenerated delay. The sign
of the value determines the polarity of the feedback. A value of +00 will eliminate any feedback.
This parameter controls both left and right levels.
10 — Vibrato Left Echo Time Range: 0 to 1500 ms
Controls the echo time for the left side. Higher settings yield a deeper echo. There are two
discrete echoes, one to the left and one to the right.
11 — Vibrato Right Echo Time Range: 0 to 1500 ms
Controls the echo time for the right side.
12 — Vibrato Echo Level Range: 00 to 99
Controls the volume of the discrete echo for both the left and right sides. A setting of 00 will
eliminate any audible echo.
13 — Bass Fc Range: 0 to 1000 Hz
Selects the cutoff frequency of the low shelving filter.
14 — Bass EQ Gain Range: -48 to +24 dB
Sets the amount of boost or cut applied to the low shelving filter.
15 — Treble Fc Range: 01KHz to 16KHz
Selects the cutoff of the upper frequency band high shelving filter.
16 — Treble EQ Gain Range: -48 to +24 dB
Sets the amount of boost or cut applied to the high shelving filter.
17 — EQ Input Level Trim Range: -24 to +00 dB
Adjusts the input volume before the EQs to eliminate the possibility of clipping boosted signals.
