Martinic AX73

Martinic AX73 is a conceptual software synthesizer engineered as a meticulous, high-fidelity virtual recreation of a rare, powerful hybrid analog synthesizer from the mid-1980s. Moving beyond the limitations and maintenance demands of vintage hardware, the AX73 plugin captures the core sonic DNA of the original unit—a blend of digitally controlled oscillators (DCOs) and genuine, analog voltage-controlled filters (VCFs)—while integrating modern features that expand its creative potential. It is the definitive tool for producers seeking the lush, massive sound of 80s analog polysynths, characterized by stable tuning, thick unison modes, and aggressive filter modulation.

The Architecture of the Hybrid Voice

The core strength of the AX73 lies in its unique hybrid voice architecture, which delivers the best of both analog and digital worlds:

• Digitally Controlled Oscillators (DCOs): The plugin models the original's DCOs, which provide the stability and precise tuning of a digital waveform generator. Crucially, each voice features three DCOs, enabling massive, thick, and phase-coherent sounds, especially when utilizing the powerful Unison Mode. This architecture is responsible for the synth's characteristically solid and stable foundation, ideal for rich pads and punching basses.

• Modeled Analog Voltage-Controlled Filters (VCFs): The signal from the DCOs is routed into a meticulously modeled, high-quality analog 4-pole resonant low-pass filter. This filter is the source of the synth's aggressive analog warmth and sonic bite. The modeling captures the non-linear behavior of the VCF, ensuring the filter introduces desirable harmonic saturation and self-oscillation when the resonance is pushed, essential for creating classic synth textures.

• Massive Unison and Chord Memory: The plugin faithfully replicates the powerful Unison mode, where all available voices are stacked on a single key press, resulting in a colossal, detuned mono sound ideal for lead lines and huge bass patches. The addition of Chord Memory allows the user to store and trigger complex chords from a single key, making arpeggiated patterns and sustained pads musically rich and immediate.

Modulation and Creative Flexibility

The AX73 V expands upon the hardware's limited modulation capabilities, transforming it into a modern sound design powerhouse:

• Modulation Routing Matrix: The original hardware was constrained by hard-wired modulation. The software introduces a flexible Modulation Matrix, allowing virtually any source (LFOs, envelopes, velocity) to be routed to multiple destinations (pitch, filter cutoff, PWM), greatly increasing the complexity and dynamic movement of the sounds.

• Extended Envelopes and LFOs: The envelopes are modeled for the characteristic 80s snap and speed, while the LFOs (Low-Frequency Oscillators) are extended with more waveforms and destination options, perfect for creating lush, evolving filter sweeps and shimmering chorus effects.

Martinic AX73 is the essential software synth for harnessing the thick, stable, and uniquely aggressive polyphonic sound of the 80s hybrid analog era.
