Intended for electric guitar and electric keyboard, the Soundblox Pro Poly-Mod Envelope Filter from Source Audio provides 23 different envelope filter effects. It gives you a variety of 2-pole and 4-pole low-pass options, as well as single peak filters, triple peak, peak/notch, and anything else that could fulfill your filtering needs—be they envelope, wah, or more dubstep in nature. Also included is a no-frills 7-band EQ, for tonal shaping without moving, modulating frequencies. A slew of controls is offered to encourage much in the way of experimentation. For instance, in addition to knobs affecting the sweep range, attack/decay speed, and center frequency, you’ll discover loads of secondary controls over LFO shapes, Q levels, customized expression pedal routing, and more. Combine the level of control with a 7-band equalizer and 6 user-assignable presets, and you’ll find yourself with a very flexible effects processor indeed. Note that there are multiple methods for controlling effects, including an envelope follower, a low-frequency oscillator (complete with tap tempo option), or various types of external control. For example, you can plug an expression pedal into its TRS input to manipulate filters as you would a wah pedal. You can also manipulate various secondary functions externally. MIDI control is also possible via a standard 5-pin DIN connection. Then you have a quirky method of manipulation sure to pique your fancy: Hot Hand control. The Hot Hand technology provided by Source Audio lets you smoothly control parameters of the pedal through its onboard sensor and a corresponding two-axis accelerometer that you can wear like a ring. In essence, by changing the position of your hand, you can modulate parameters of the pedal in a fluid fashion. Also, a sensor output is built into the pedal to facilitate the daisy-chaining of other Hot Hand enabled pedals, giving you one ring to rule them all (your pedals, that is). All the effects are achieved digitally, via the pedal’s 56-bit DSP architecture, and utilizing 24-bit conversion stages at the AD and DA stages to preserve signal integrity as your audio travels through the pedal. A 9 VDC power supply is provided with the unit. Specifications 23 Filter Sounds including 2-Pole Low Pass, 4-Pole Low Pass, Single Peak, Triple Peak, Peak & Notch, and Phasers. Positive and Negative filter sweep with variable range and sensitivity. Wet/Dry Mix knob featuring our signature low-end preserving algorithm Lo-Retain™. 4 modulation sources including envelope, LFO, expression pedal and Hot Hand. Tap tempo speed control for LFO. State-of-the-art DSP—Our proprietary 56-bit Digitial Signal Processor, the SA601, and crystal clear 24-bit converters. 6 user presets—Easy to configure user presets in two banks selectable via 3 footswitches for quick access of your favorite sounds. 7-Band Equalizer—Ultra-precise 7-band equalizer for in-depth tone control saved per preset. Extended Control—An expression input allows for control of a wide variety of pedal parameters. A MIDI input also allows external access to presets and parameters.
