AXTRO-FM is a powerful FM synthesizer designed to deliver rich and dynamic sounds. It features five oscillators and a noise generator, offering 11 different modes and algorithms to shape your audio. The synthesizer includes three filter types—bandpass, state variable, and band reject—along with an expressive envelope and multiple LFO stations for intricate modulation possibilities.

This plugin also incorporates a Chord control that allows you to craft custom chords with up to four notes, enhancing harmonic complexity in your compositions. A built-in note sequencer and piano roll provide seamless pattern creation, while eight master effects—including compressor, EQ, distortion, delay, chorus, flanger, phaser, and reverb—enable comprehensive sound shaping directly within the synth. These effects can be blended to the output through intuitive control knobs.

AXTRO-FM includes a recording station supporting up to 16 bars, allowing you to capture your ideas internally without relying on external tools. With a library of 512 presets across various categories, it offers a wide range of starting points for sound design. Compatible with Windows 10 and 11 (VST2/VST3 64-bit) and macOS Catalina or later (AU/VST3 64-bit) on Apple Silicon processors, this plugin is available for $60.
