The FT201 Analog Filter / 10-Step Sequencer is our innovative voltage controlled vactrol state variable filter combined with a 10 step sequencer. The FT201 is capable of providing ultra low and high frequency filter effects which are controllable with the on board infrared expression controller, which allows the user to create filter sweeps by moving their feet or hands over the pedal. The FT201 has 3 different filter outputs: bandpass, low pass and high pass, which all work simultaneously. The cutoff frequency range is very large, between 20 Hz and 20 kHz and because of the vactrols used the sound quality is superb. The 10 Step Sequencer runs through the selected amount of steps (2 – 10 steps) and adds the control voltage to the value set by the Cutoff knob, thus modulating the cutoff frequency in every step.
