The Aqueduct by Earthquaker devices is pitch vibrato with EIGHT modulation modes! According to Earthquaker, it delivers “synth-like sonar pulses, touch-sensitive frequency modulation, gentle rolling pitch-wobbles, steady kosmische pulsations, rapid trills, slimy sonic squiggles, whammy bar wiggles, pitch bends, pseudo-flange, and anything else your pitch-warped brain can picture in your murky mind’s eye.”
There are three dials: Rate, Depth, and mode.
Rate controls the speed of the modulation, depth controls the intensity of the modulation.
The different wave forms are:
- Sine: This is your standard vibrato sound
- Triangle: A lot like the sine wave, but a sharper rise and fall. According to Earthquaker, this creates “a more pronounced pitch bend at the peak of each LFO cycle.”
- Ramp: This is a triangle wave that hits hard initially, then has”a rapid downward slope with a synthesizer-like sustain and release.”
- Square: This is where things start to get jarring. Square waves are known for being choppy — no gentle ups and downs here. You’re on, then you’re off, then on, off, on off etc. It’s great for trills when your fingers are sore.
- Random: You get what you get with this one. Lower depth is more warbly vinyl, higher depth is [insert shrug emoji].
- Envelope-Controlled Depth: it’s a sine wave where rate controls speed, and depth control “sets the sensitivity of the envelope – the point at which the effect kicks in as you play.” The harder you play, the more pronounced the effect.
- Envelope-Controlled Rate: It’s another sine wave, but, in this mode, the input level (i.e., pick attack) controls the LFO rate. According to Earthquaker, you play harder for faster modulation or softly for slower modulation speeds. The Rate control adjusts the sensitivity of the envelope. Depth selects the LFO intensity.
- Envelope-Controlled Pitch: This one’s a little weird (despite being a sine wave), so I’m quoting a lot from the Earthquaker site. “Shape, and frequency modulation is controlled by the dynamics of your pick attack and not the LFO.” Depth sets the wet/dry mix. Rate sets the sensitivity and overall range of the pitch bend.
