Back in 1986, the synthesizer scene was dominated by digital technology, causing the original AX73 to be overlooked despite its all-analog signal path. Martinic has taken the best aspects of the AX73 and transformed it into a versatile software instrument that is perfect for modern producers.

The AX73 plugin (available in VST/AU/CLAP formats) boasts four analog oscillators spread across two synth layers, along with distinct modulation capabilities, expanded performance options, and an eight-module effects section. Our Advanced Circuitry Emulation technology perfectly models the original hardware, eliminating the need for complex menu navigation.

With over 600 preloaded presets, this AX73 plugin is a one-stop-shop for the creation of immersive and dynamic soundscapes.

Key Features:

  • The Martinic AX73 is an analog subtractive synth which boasts two layers, each with two voltage controlled oscillators. These layers can be split across the keyboard, or stacked, effectively giving a four-oscillator synthesizer. The original AX73 had six-voice polyphony but Martinic has increased that to up to 24 voices.
  • Each layer has a filter, a chorus, and modulation from four envelopes and four LFOs. The Martinic AX73 also houses two arpeggiators – one per layer. The original AX73 did not have an arpeggiator; this arp is actually modelled on that of the AX60.
  • Martinic has also added a comprehensive, eight-unit effects section. The effects section includes: Compressor, Phaser, Flanger, Chorus, Delay, Reverb, Distortion and EQ. The effects can be arranged in any order using the FX Chain.

System Requirements:

  • AX73 is available as a VST 2.4, AU (Audio Units) or CLAP (CLever Audio Plugin) instrument plugin, which means it needs to run inside VST, AU or CLAP hosting software, e.g. Ableton Live, Cubase, GarageBand, Logic Pro, REAPER, Studio One, etc.
  • Although AX73 should be able to run at any sample rate the host provides, a rate of at least 44.1kHz is recommended.
  • The plugin is designed to run on Windows 7 or newer as a 32-bit or 64-bit plugin, or Mac OS X 10.9 (Mavericks) or newer as a 64-bit plugin.
