Thavius Beck demonstrates how enabling a global key signature in Bitwig changes a note transposer's behavior from shifting in semitones to shifting in scale degrees, and then modulates that parameter with a step sequencer to create evolving modal changes from a single looping clip.
The key insight is that scale-degree transposition keeps every shift musically in-key, so even randomized or sequenced jumps land on notes that belong to the scale rather than landing on arbitrary chromatic pitches. Thavius sets up a four-step sequence, each step sending a different scale-degree value, turning a one-bar pattern into something that shifts character every bar.
He also shows how to fine-tune modulation targets in Bitwig's Inspector panel, including setting exact values by typing and adjusting the slope of the modulation curve between linear, logarithmic, and exponential responses. The workflow here is a good example of Bitwig's modulation-first philosophy: any value, not just knobs, can be a modulation target.
