Look up onI've used this mostly as part of an fx send but it also works really well with an oscillator as an input. An amazing module for really unique and complex sounds as well as incredible atmospheres. The giant knob is very performative and the build of XAOC Devices is always top tier.::Original Box Included::Koszalin is a full stereo frequency shifter (2 ins / 4 outs) offering both quasi-exponential and linear frequency change of up to +/-5kHz as well as full stereo feedback under voltage control. Frequency shifting results in linear translation of signal spectrum producing all kinds of atonal sounds. It should not be confused with frequency scaling, also known as pitch shifting. Complex phase cancellation patterns occurring with frequency shifting and deep feedback produce spectacular barber-pole effects. Koszalin offers direct control of feedback amount, feedback routing, and feedback response. It also facilitates frequency modulation of any stereo audio signal, thanks to the linear TZFM input.
