Roland ED PC-300 working driver for macOS !

Dear all,

Just when I thought it was useless to install my old RolandED PC-300 on my daughter's MacBook Air running macOS Monterey 12.6.1 to teach her some music with GarageBand, I came upon this post : 3428845

And it worked fine ! I still can't believe it !

1) Download GenericUSBMidi.plugin

2) Unzip and copy to Macintosh HD > Library > Audio > MIDI Drivers (but remove previous plugins)

3) Enable the driver in Security & Privacy

Et voilà !

My eternal gratitude to all those who have made this possible.
