Source Audio Soundblox 2 Stingray Multi-Filter - Manual (Page 12)

12 | Controls: Knobs
MOD SOURCE Knob: When Hot Hand, MIDI, or an expression pedal are not
being used, the STINGRAY features 6 different types of modulation control:
Slow Attack Envelope Follower, Sine Wave LFO, Square Wave LFO, Random
Sample and Hold, Sawtooth Wave LFO, and Fast Attack Envelope Follower.
The MOD SOURCE knob controls a gradual blend in between each selection,
so setting this knob between two of the modulation graphics will create a
sound with features of both modulation forms.
• Slow Attack Envelope Follower ( ): The Envelope Follower
produces a control signal based on the volume of your instrument. Varying
your playing dynamics will change how this control signal affects the sound.
By using the SPEED knob, you can adjust the timing of the Attack and Decay
to control the rise and fall of the control signal.
• Sine Wave LFO ( ): The Sine Wave LFO produces a very smooth
and uniformly moving modulation. Use the Sine Wave LFO for a more
traditional chorus or phaser-like effect.
• Square Wave LFO ( ): Unlike the smooth modulation of a Sine
Wave, the Square Wave LFO has a blockish sound of extreme peaks and
valleys. Use the Square Wave LFO for a dramatic, choppy sounding effect.
• Sawtooth Wave LFO ( ): The Sawtooth Wave LFO has similarities
to both the Sine and Square wave, producing smooth rises to the peak like
the Sine wave, but a dramatic drops like the Square Wave.
• Random Sample and Hold ( ): This modulation source utilizes a
randomized staircase waveform that recreates the chaotic filter sounds
found in some vintage analog synthesizers.
• Fast Attack Envelope Follower ( ): The Attack, or rise of the
control signal, is set to a fixed “fast” speed. By using the SPEED knob, you
can adjust the timing of the Decay, which is the fall of the control signal.

To access Extended Mode, hold the CONTROL INPUT button while quickly
pressing the OPTION SELECT button. You can switch back to Normal Mode
by doing the same procedure. Extended Mode is a global setting for the
pedal and is not saved per preset.
The filter effects featured in the STINGRAY are further described, followed by
the order in which they appear in Normal and Extended Modes.
Low Pass Filter: allows only low frequencies to pass through while
removing high frequencies from your signal.
High Pass Filter: allows only high frequencies to pass through, while
removing low frequencies from your signal.
Band Pass Filter: allows a grouped section of frequencies to pass through,
while removing the remainder of the frequency spectrum.
Peak Filter: allows the full frequency spectrum to pass through as it peaks
(or boosts) a narrow range of frequencies.
Notch Filter: notches (or removes) frequencies in a narrow range.
