FEATURES
The Soundblox Pro Poly-Mod Filter is a very flexible envelope filter effect.
The unit features multiple filter types ranging from simple to complex,
which can all be controlled by an Envelope Follower, an LFO (Low-Fre-
quency Oscillator), the Hot Hand Motion Sensor or an Expression Pedal.
An Envelope Follower is an algorithm that responds to the amplitude (or
volume) of the incoming signal and creates a control signal based on the
input level. This control signal is used to modulate the filter to create an
auto-wah effect. (Note: The envelope follower signal can be reset to zero
between notes by a very brief moment of silence, allowing the next note
played to experience the full sweep of the filter effect all the way from its
starting point)
An LFO (low frequency oscillator) is an electronic signal that uses a
rhythmic pulse or sweep to create a control signal. This control signal is
used to modulate the filters of the Poly-Mod Pro to create an oscillating
filter or sequencer-like effect. The Poly-Mod Pro also features a variety
of LFO shapes including sine, square, saw, step and triangle, each of
which can dramatically change the sound of the effect.
The Hot Hand Motion Sensor uses data from an accelerometer placed
inside a wearable ring to modulate the filters of the Poly-Mod Pro. Either
a wired or wireless sensor can be plugged into the sensor input on the
back panel. After the sensor is plugged in, use the MOD SOURCE button
to select “Hot Hand Mode”. At this point the controls take on slightly dif-
ferent functions. Note that the calibrate feature is intended for use with
the “Hot Hand Mode” only.
An Expression Pedal can be used to control a variety of selectable pa-
rameters in the Poly-Mod Pro including direct filter modulation like a
standard wah pedal.
The Poly-Mod Pro features LO-RETAIN, an algorithm that alleviates the
issue of low-end “tone suck.”
