This short excerpt from Bitwig's modular tutorial series breaks down the 0-to-1 phase signal at the core of The Grid's step sequencer lookup system. The host uses a Value knob to manually scrub through a phase signal, showing how each position maps proportionally to a step in an eight-step sequence.
The key insight is that phase wraps via a modulo function: any value, no matter how large or negative, gets its integer portion stripped away, leaving only the decimal remainder as the usable 0-to-1 range. This means even messy or unclean math stays in alignment automatically.
