The 2.x release notes say the tonics are lit green, but this isn't the case in the factory setups. In Eigenharp Clubhouse 38 today Geert said this was a deliberate decision to keep the factory setups as close to 1.x as possible. However the 2.x installation does come with scripts (in the Lights folder) to light the tonics in the factory setup of the Alpha and Tau. The Pico has sadly been overlooked.
Geert said he would put together such a script if he had some time (for which, many thanks, Geert), so this is a note for him, as requested. If anyone's already done this then do please post the script here to save Geert the work.
