Now it's also NuRAD firmware! Set define for compile option NURAD in hardware.h to switch. Added a new little thing for NuEVI too: releasing the rollers leaves octave in current one instead of going to bottom octave unless coming down from first roller. This is helpful against bass hum from filter leak when setting the EVI aside, using pitch CV from NuEVI and synth with no VCA in use or gate open (drone mode).
