Audio Demos

Are there any differences in software between Limited Editions?

Limited Edition Grannies were sold with different versions of software, as it was approaching its final version. Since the first version of MG2 came out, we have updated the software several times. The software gets better and better thanks to your feedback! Big thanks! <3

Anyway, it is possible to update your Atmega microcontroller with the newest arduino software posted on our GitHub. Still, we know that not all of the current MG2 users own a programmer, or can handle the update on their own. So you can get the preprogrammed chip with the newest firmware HERE.
