I bought this midi converter as my old Roland Um-One was not compatible with a new Macbook. The cable worked immediately with no issues, and was instantly recognised by my DAW / laptop.
I've been using the cable for a few weeks now, and have experienced no issues at all.
The USB-C connection is really handy when using a MacBook as no hub / adapter is necessary, and for anyone using a standard USB port, an adapter is included which although this adapter first appears a little cheap looking, it works well and provides a secure connection.
The cable has no LED indicator lights like the Roland UM-One cables do on the central box, but this isn't really necessary to the functioning.
Does exactly what's needed, and at a reasonable price. Would definitely recommend.
