Source Audio Soundblox 2 Manta Bass Filter - Manual (Page 13)

Controls: Knobs | 13
SPEED Knob: Depending on the modulation source, the SPEED knob controls
either the rate of the LFO, the attack and decay times of the envelope followers, or
the “Smoothing” of the Hot Hand.
When using the LFO modulation ( , , or ), turning the SPEED knob
clock-wise will increase the modulation rate.
When using the Slow Attack Envelope Follower ( ), turning the SPEED knob
clock-wise shortens the time of the Attack and the Decay, which is the rise and fall
of the control signal. In this setting, the Attack and Decay are set proportionally to
each other. When using the Fast Attack Envelope Follower ( ), turning the
SPEED knob clock-wise lengthens the time of the Decay only. The Attack is
programmed at a “fast” rate, which matches the fastest setting of the Slow Attack
Envelope Follower.
While Hot Hand is engaged, the SPEED knob controls the amount of “Smoothing”.
Turning the SPEED knob clock-wise increases the “Smoothing”, and makes Hot
Hand less responsive and less jittery sounding.
Discovering Preset Knob Positions
Since the MANTA preset values can differ from the physical knob positions, it may
be useful to determine the positions of the preset knob values. To start the
process, put the pedal in bypass mode and set all the knobs to their full
counter-clockwise positions. Next, enable the preset, and slowly turn each knob
up one at a time, until the preset indicator LED begins to blink rapidly. This rapid
blinking indicates that the current position of the knob matches the saved value.
