This excerpt from Bitwig's official Grid tutorial series focuses on a practical patch where a step sequencer drives a filter cutoff, with most step values kept low so the filter only occasionally opens up. The host then introduces the Phase Reset module, which restarts the sequencer's position on each new note trigger, turning a static loop into something that evolves differently depending on when and how you play it.
Switching the patch from monophonic to polyphonic is where things get interesting. With multiple voices active simultaneously, each note gets its own independent playhead moving through the step sequence at its own position in the phase cycle. The Grid's visualizer makes this concrete: you can watch all the individual playheads running in parallel, each at a different offset.
The host also demonstrates doubling the global phase speed, compressing the sequence to run across eight sixteenth notes instead of sixteen. Combined with polyphony and phase reset, this creates rhythmic and timbral variation that feels alive without any automation or manual intervention.
