Let's Build an... Arpeggiator

This tutorial builds an arpeggiator. Starting from the idea of cycling thru each note that is held down, we investigate pitch control via signal, domain scaling, pitch quantization techniques, building a change-detection circuit, and tweaking phase and timing for a stereo arpeggiator. Approach building in The Grid like any sound design task — start with a known target and find unique ideas in the journey.

Let's Build an... Everything

Each episode in this series starts with an idea, and then we make it in The Grid (the modular sound-design environment of Bitwig Studio). As with any sound design process, the task at hand provides structure, but creative impulses may lead us off the beaten path. Please put on the goggles; the workbench is ready for action.

Let’s Build A... is an ongoing tutorial series, with a new episode dropping every few weeks. Check back soon.
