The Octave Cat Black Friday deal takes 51% off Cherry Audio's synth plugin, which brings it to $24 until Nov 27, 2026.
Octave Cat is a software version of The CAT, the duophonic synthesizer Octave Electronics released in 1976. Cherry Audio built it together with The CAT's original designer, Carmine Bonanno.
The maker says it keeps the growl of the hardware and its aggressive resonant filter. It also carries over the oscillator cross-mod and the oscillator sync.
The hardware CAT could not save patches or take modulation from an external MIDI controller, and it was not fully polyphonic. Bonanno says Octave Cat goes well beyond it on all three counts.
The plugin runs as mono, duo or polyphonic, with up to 16 voices. Unison is available in the mono and duo modes.
A second panel holds the FX section and a dual eight-step sequencer. The sequencer can be assigned to oscillator pitch, filter cutoff and VCA amplitude, with tempo sync, quantization and keyboard transpose.
On the effects side you get tube and fuzz distortion, a phaser with 2, 4, 8 or 12 stages, a combined flanger and chorus, delays in three syncable flavors, and five reverb types.
Octave Cat supports MPE for pitch, channel pressure and timbre. Channel pressure and polyphonic aftertouch can also act as polyphonic modulation sources.
Every control takes MIDI learn and DAW automation. You can pick the original Mark I skin or the later SRM look.
There is also a user-adjustable oversampling control, and Cherry Audio's Focus zoom for close work on the panel.
Octave Cat comes in AU, VST, VST3, AAX and standalone formats. It needs 21 MB of disk space and an internet connection for activation.
