    Frequently Asked Questions


    What is a step sequencer?

    A step sequencer is an interactive interface that allows users to program musical loops by clicking grid squares representing increments of time (steps) and pitches.

    Why is the root row highlighted?

    The root note (e.g. C in C Major) serves as the tonic home of the melody. Highlighting it helps you visually track key centers when composing lines.

    Can I change scale settings mid-composition?

    Yes. Changing key, scale, or tone reshapes the pitches mapped to the grid in real time without losing your active step positions.
