Description

GridStep is a professional MIDI step sequencer designed for clarity, control, and predictable results. It works as a standalone app as well as an AUv3 plugin.

GridStep provides a focused grid-based workflow with explicit edit modes, per-step inspection, and one-shot generation tools. Every interaction is intentional, allowing patterns to evolve without ambiguity.
