Matthew, OMG I finally managed to upload your gorgeous MODLFO. It is so wonderful. My nano is a crazed chaos machine and I haven’t even brought the envelopes and attenuators into play. OMG.
Paul and everybody who may have had trouble compiling and uploading: Niklas has blessed us with step by step guidance here https://www.sound-machines.it/forums/topic/what-if-i-want-the-original-firmware-back/ that provided all the missing pieces that I was missing.
When I compiled the MODLFO sketch after following Niklas’ instructions, I got some things that looked like error messages, but they must have been minor, because I hit UPLOAD anyway and it WORKED. (I guess if the errors were bad it would have refused to upload.)
Anyway thanks so much to Matthew and Niklas, and I hope everybody finds the path to nanomodular joy. Let us know how it goes. And thanks Davide for such a wonderful box of miracles. Please make more! Please make a west coast sibling! And may all your dreams come true!
