Because the MIDI standard calls for active opto-isolator electronics, Meris recommends this box over a passive MIDI-to-TRS cable, which can suffer grounding issues, latency, or unreliable operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMade for the Meris Enzo, Hedra, Mercury7, Ottobit Jr. and Polymoon — the compact pedals whose EXP jack can be set to MIDI mode in the global settings.
