Hello, looking for some help. I'd like to use the Boss MS-3 patches to change presets in the Source Audio C4 Synth. I'm still confused about MIDI and how to set this up. The switcher has USB and MIDI but the C4 only has USB. Will I need a MIDI USB interface between the two units in order for them to communicate? I understand Source Audio offers the Neuro Hub but from their description of it I can't quite understand what its purpose is.
