Catalyst is a powerful VST/AU sequencer plugin designed to inspire creativity and streamline the music production process. It enables you to effortlessly craft a wide range of synth parts, including basslines, melodies, chord progressions, and arpeggios, all within a single interface. This plugin is ideal for producers looking to break free from traditional piano roll sequencing and explore new melodic possibilities.

The plugin features five distinct modules that can be activated separately or combined for complex results. The step sequencer allows you to program monophonic patterns and perform them live on your MIDI keyboard. The harmonizer converts single notes into full chords that align perfectly with your song’s key and scale, while the arpeggiator transforms chords into dynamic melodic patterns. Additionally, Catalyst can host any VST, VST3, or AU synth plugin directly, enabling seamless sound design and performance without the need for additional tracks.

Catalyst also includes parameter automation with dedicated step sequencers, allowing precise control over synth plugin parameters in a style reminiscent of parameter locks. By integrating key and scale awareness, it ensures every note fits harmonically, encouraging experimentation without the risk of dissonance. With its built-in synth hosting and audio output capabilities, Catalyst simplifies your workflow by eliminating complicated MIDI routing, making it a highly efficient tool for modern music production.
