thanks

  • enormous thanks to Olivier Gillet of Mutable Instruments for all of the wonderful open-source code which we have ported to and re-used in o_C
  • Paul Stoffregen, creator of Teensy and associated firmware libraries used by the o_C module
  • Nils “Titanium” for the nifty cheatsheet (the images from which are reproduced in the manual)
  • Bret Truchan for permission to use byte beats equations which he collected, devised and curated for the excellent Microbe Modular Equation Composer module, which is highly recommended for anyone interested in byte beats
  • Stephen from Noise Engineering for helpful notes and info about the neo-Riemannian transformation implementation in his Tonnetz Sequent module, which is highly recommended for anyone interested in tonnetz harmonies.
