USER MANUAL

June 2nd 2020

We always value feedback and ideas, so feel free to reach out.

Please check the website for the latest firmware!

THANK-YOU!

Thank-you for adopting MEGAfm, the product of several years of work &

play. We are particularly fond of the YM2612 as they offer a unique gritty

texture that is uncommon in the FM word, plus hands-on FM experience

that is unprecedented in the hardware FM synthesiser world.

We hope that you will enjoy making music with MEGAfm as much as we

have enjoyed and continue to enjoy developing it!
