POLYPHONIC SYNTHESIZER · THE PULSAR MODULAR P900 HERITAGE

ZORBA

Forty years of analog DNA. One instrument.

Built on the Pulsar Modular P900 analog heritage, Zorba can be a Juno on your first patch, a Jupiter on your second, and something neither could have imagined on your third. Three oscillators, two filters, three envelopes, two LFOs, an arpeggiator with accents and a modulation matrix that connects almost anything to almost anything else.

V2 COMING SOON

Purchasing and the free trial are paused until the next version ships.

AU, VST3, AAX Polyphonic · MONO · UNISON · zero latency
Zorba: the walnut panel with the LCD display, three oscillators, two filters, three envelopes, two LFOs, the arpeggiator and the modulation matrix

Forty years of analog DNA, one signal path.

“The result is an instrument that can be a Juno on your first patch, a Jupiter on your second, and something neither could dream of on your third. All of it built on a signal path that honors the Pulsar Modular P900 analog heritage.”

Ziad Sidawi, Zorba designer, preface of the user guide

Three oscillators start the sound. VCO1 and VCO2 morph continuously from saw through square and triangle to sine, with FM between them in a linear and a cross-mod flavor, and VCO3 is an independent sub an octave below with its own tune, gain and filter routing. The noise generator runs on its own path with its own filters, so breath, key click and chorus haze sit on top of the tone instead of being shaped by it. Two filters share the 904-F state variable design, low-pass, band-pass, high-pass and notch, with a resonance that travels from clean through self-oscillation and saturation into the Black Hole zone, and they run independent, linked or in series.

Three envelopes, two LFOs and an arpeggiator with a five-step accent pattern feed a modulation matrix of twelve sources and 38 targets, 208 routes with no slot limits and defaults that make the first patch playable before you touch a thing. A plate reverb sits at the end, from a tight room to a long decay. Zero samples of latency and no convolution anywhere keep it feeling like hardware and light on the CPU, so instances stack without a second thought. MIDI-Learn, polyphonic aftertouch and a breath source cover the performance side.

THE VOICE IN NUMBERS
3 VCOTwo morphing primaries and one dedicated sub an octave below, with its own tune, gain and filter routing.
2 VCF904-F state variable, four modes each, resonance through four zones; OFF, FOLLOW or SERIES between them.
3 EG · 2 LFOEG1 on the VCA, EG2 on both cutoffs, EG3 free in the matrix; LFO1 mono, LFO2 mono or poly.
208 ROUTESTwelve sources, 38 targets, every route with its own depth, no slot limits.
OSCILLATORS · FM
Continuous waveform morph on VCO1 and VCO2 with a Hybrid zone no fixed-waveform synth reaches; linear FM for bells and electric pianos, X-MOD for the exponential, inharmonic territory; hard sync; four noise types on an independent path.
FILTERS · COUPLING
Two 904-F state variable filters: low-pass, band-pass, high-pass and notch, resonance from clean through self-oscillation and transformer saturation to the Black Hole zone. OFF, FOLLOW or SERIES ties them together.
MODULATION · ARP
Three envelopes, two LFOs, an arpeggiator with a five-step OFF, HALF, FULL accent pattern that loops independently of the held chord, and the matrix that connects them: 12 sources, 38 targets, 208 routes.
REVERB · PERFORMANCE
A plate reverb from 0.47 to 9.31 seconds, zero to bypass. MIDI-Learn with saved mapping sets, polyphonic aftertouch into a single held voice, a dedicated breath source, glide with its own modes and types.

Zorba is something special. It sounds amazing even without processing, and the interface is clean and effortless-no unnecessary complexity. I only had the demo but I'll be buying it as soon as I can afford it. One of the few software synths that truly rivals hardware.

Hello,
I’m a sound junkie and a hardware freak.
Plugins that emulate "analog synthesizers" used to be a no-go for me. But when the P900 came out, I was surprised by the sound—
and now I’m thrilled with Zorba.
Best of luck to the team!

Zorba is currently the only software synth that matches naturally with my vintage analog collection. (Moog, Sequential, Roland, Andromeda)

Zorba has that extra dimension I usually only find in hardware. Magical, powerful, smooth and wide.

This is really incredible !
I own a lot of virtual synths and my reactions to the first test of this beast has been really funny :-)
You know all those VSTs with sounds full of “makeup” like chorus, reverbs, delays etc…
This one is dry…no makeup…but it sounds real !A beautiful lady with analog rough character .
No need to makeup, but put a reverb on it and you are in pure heaven !
It also has its beautiful Plate reverb too if needed :-)
It sounds organic and it can have different personalities .
I have to say that in my studio I have different analog synthesizers (Moog,Oberheim,Dave Smith,Korg,Roland …etc) so I know what I am talking about .
Guys you made a masterpiece ,the wait was really worth it ,thank you for your precious work !
