Just like the T-Resonator the module consists of two individual audio paths as well, which can and should be intertwined in an interesting manner! The module features inputs and outputs in stereo i.e. it can be used either mono or stereo.
An audio signal whose level is adjusted with GAIN first is processed by two parallel cascade low pass filters. Theis cutoff frequencies is variable individually but at the same time it can be modulated simultaneously be the LFO or Envelope Follwer + LFO (control via Intensity). Additionally it is possible to determine for each filter how strong and in which direction the Envelope Follower works.
Instead of a usual resonence control the filters have bipolar feedback potentiometers: clockwise they dial in a positive feedback which acst like resonance. But counterclockwise they generate a negative feedback with a different behavoiur which generates drastic sub-frequencies (watch your speakers!).
The left filter's output can be sent to the right filter's input via the MIX control, which happens either phase correct or phase inverted. Alone this fact, screaming, feedbacked filters being fed back and forth create a lot of experimntal noise.
But the T-Rackonizer doesn't stop here: Each channel can be sent to the internal digital effect via the Delay In parameter, again phase-correct or with inverted phase. Eight effect programs are available (tracker, siner, warp, wave guide, two delays, two reverbs), each with two parameters, see faceplate. The feedback of each effect channel is set with the Delay Feedback parameter.
Voltage control of parameters is available for each filters' feedback, the cutoff frequency and the Mix. Furthermore the effect programs can be selected via a CV as well.
