Toneworks Catalyst v1.1.137 WiN

Toneworks Catalyst is a creative sequencer plugin for developing basslines, melodies, chord progressions and arpeggios. It gives hobby producers an alternative to drawing every note in a DAW’s piano roll, with tools for building synth patterns that stay within the key of a track.

Catalyst can host synth plugins internally, bringing sound generation and sequence creation into the same workspace. Dedicated step sequencers let you automate parameters, adding movement to a pattern alongside its notes. Whether you are sketching a bass part or exploring a chord sequence, this approach offers another way to find musical ideas when your usual workflow feels repetitive.

The plugin suits producers who enjoy pattern-based writing and want to explore both traditional and contemporary synth sequences. This Windows version is relevant to FL Studio and Ableton Live users working with VST plugins. Catalyst is primarily a composition and sequencing tool: its role is to help shape musical parts and control hosted synths rather than replace your DAW.
