I have made a few multipurpose boards, that could work as simple midi to i2c adapter if anyone feels interested.
It features din midi in, trough 3.5mm connector (and out) 2 i2c ports trough 3.5mm connectors, an encoder and a display, i might just populate midi in an i2c connector for this purpose.
I have not populated them yet, but the design is from another board ive made that works.
I have a few to sell once populated and tested, that said i’m no expert in electronics or programming,
so this is a solution for those feeling desperate as i once did. Otherwise i suggest you wait for transit:
more info to come…
Aiming at around 50eu or lower
My prototype firmware sends two four voice poly channels that rotates trough the free voices prioritizing the first channel that was freed. To not cut off the decay/release envelopes. Then a lot of mono channels and cc’s(can’t remember how many, but it makes use of the 100 i2c channels of the 301)
Todo: add midi clock and start stop messages
