I challenged myself to build a rich patch that would work on pressing a single note (C3) on the keyboard. This patch uses only the analog engine oscillators and the utility engine in Pigments 4. All the effects are internal to the synthesizer apart from some compression and EQ at the end. I did not use the arpeggiator or sequencer at all; the layer of arpeggiated sounds come from modulating the pitch with a custom quantization setting.
