This patch is in response to Omri Cohen’s March 2025 challenge, “Pi.” The clockrate and most of the modulation values are set to standard fractions of pi found on the Unit Circle. The key centers move in order of the cycle of fourths.

For this patch, I did use the premium module “Oneiroi” from Befaco, https://library.vcvrack.com/BefacoOneiroi/Oneiroi. This was used for the drone, but you can substitute any drone patch you wish using free modules.
