Get your synth sounds purring with the Behringer CAT, an authentic reproduction of the famous Octave CAT SRM II synthesizer featuring a duophonic mode that allows each oscillator to be independently controlled. The synthesizer has four mixable waveforms, an external input for processing, and a highly flexible modulation matrix for insane sound design potential.
The CAT offers 47 controls for direct and real-time access to all important parameters. The synthesizer can be removed from its desktop enclosure and placed into a Eurorack-compatible case (70 HP). A power adapter is included.

Keyboard Control
The CAT can accept any keyboard controller via MIDI. The signals generated can be tweaked via the Pitch Bend slider, which can bend a note up or down one octave. Bump this up to two octaves by flipping the Octave Shift switch up or down. Use the Glide slider to change how fast a note transitions to another; up is faster, and down is slower. Combine that with the LFO Freq slider to control the LFO and ADSR repeat tempo, and you can create some amazing pulsating portamentos.
Two VCOs
The very heart of the CAT's sound is its two VCOs. The Duophonic/Paraphonic nature of the CAT allows both oscillators to be controlled independently. Use the Fine and Coarse Frequency controls to tune VCO1 to VCO2. Keyboard control on the CAT can be set to either Mono or Poly. Poly mode lets VCO1 generate the highest note played on the keyboard while VCO2 handles the lowest, allowing two notes to be played simultaneously. Setting the switch to Mono mode makes VCO1 generate the lowest note depressed on the keyboard.
Make Waves
Waveform switches on both VCOs allow different waveforms to be patched in from the LFO. Choose between Sine, Square, Sample plus Hold, and even pitch modulation through each VCO. Turning the Modulation Depth knobs in either direction controls the intensity of the effect. The VCO2 also comes with a Sync switch that locks VCO1 with it to act as one huge oscillator to produce more complex waveforms and dramatic results. Mix VCO1 into VCO2, or vice versa, and the CAT can produce some tasty tones that make themselves at home in your next synth jam.
Slide In
Each VCO on the CAT comes equipped with its own waveform sliders for adjusting the volume of each type of VCO waveform. Pump up the Sub Octave, Sawtooth, Square, Triangle, or Pulse waves, or mix them all together and create some truly unique tones.
VCF
As if combining two VCOs wasn't amazing enough, the CAT comes with another set of claws in the form of a VCF filter section. You can get more complex and robust tones by incorporating VCO1 into the mix. Introduce more waveforms and manipulate the Q slider to emphasize harmonics, as well as the Filter Cutoff slider, which acts as a low-pass filter. Turn the CAT into a really funky bass machine or an out-of-this-world synth that creates some searing lead tones. You can even create some amazing drum sounds by manipulating the VCOs, VCF, and ADSR.
Envelope
To give the signal even more character, you can use the CAT's Transient Generator to create a detailed voltage transient every time a key is depressed. Adjust the Attack, Decay, Sustain, and Release via the matching sliders to shape your signal. The AR transient generator works similarly to the ADSR but with less detailed control over the envelope. You can also set the ADSR to automatically repeat or only when a key is held down. The Sample and Hold switch can be set so the VCO1 setting is sampled, or when set to Noise mode, produce a random output pattern. Slide the LFO Delay control up or down to determine when the LFO will reach its maximum output after a key is depressed.
Ins & Outs
The CAT features a whole slew of Inputs and Outputs that expand its capabilities beyond what you can see out of the box. You can route external control voltages to VCO1/2 or the VCF and even pump some external line-level audio into the CAT. You can even connect the CAT to other external synthesizers through the Gate, ADSR, AR, or Keyboard outputs. The CAT's 16-note Poly Chain function lets you combine multiple synthesizers for up to 16-voice polyphony, and it provides vastly improved reliability and stability over its 1970s and '80s predecessors.
