Greetings from Florida! I need some help on figuring out which interface I should get.
I use an iMac running macOS 10.14.6. I have a Samson G-Track Pro USB mic and a Zoom H5 Handy Recorder. I have two keyboards.
I need to purchase a midi interface. I don't know if I should purchase something like a iConnectivity mio2 2x2 MIDI Interface or a iConnectMIDI2+ 2x2 Multi-Host USB MIDI Interface or MOTU FastLane USB 2x2 MIDI interface. These all have two midi ins/outs.

Or a device like the Focusrite Scarlett 4i4 which has both audio and midi (but only one in/out midi).

Any suggestions and recommendations?

Thanks.
