From a Bitwig Studio session on creative patching in The Grid, this bit shows how to build a patch that automatically shifts its harmony interval based on how many notes you're holding down. The presenter focuses on six key modules and walks through the logic clearly, making the idea easy to follow even if you're new to modular thinking.
The core technique uses a note-count module to detect whether more than one key is held. When you play a single note, a minor third gets added on top. The moment you play multiple notes, the patch detects that and switches the harmony to a fifth, which stacks cleanly across polyphonic playing without clashing.
The broader takeaway is about connecting a utility signal to a musical decision. A module that simply counts held notes becomes a condition that shapes the character of your harmony in real time, with no manual switching required.
