There are such adapters, the problem is known. They can be found, for example, on aliexpress - the cheapest one costs about $ 25. There is also a bare board with wires for self-soldering, I am also looking for such a solution. Hopefully it will work.

How could I use the Artiphon Orba to control my Moog Sub 37? It has 5 pin dim midi input. Thanks! #ArtiphonOrba #MoogSub37 #Moog
