This product is perfect for me, because my electronic drum kit is far away from my MIDi interface, this MIDI merge is placed halfway between my electronic drum kit and my MIDI interface, and I connected my electronic drum kit with a standard length of MIDI cable to the MIDI merge, and then a standard length of MIDI cable from the MIDI merge to my MIDI interface, it is a long distance, but thanks to the MIDI merge I get no MIDI delay at all. and I'm left with three MIDI ins on the MIDI merge, Which is ideal! Because I have had many musicians that always want to use their own MIDI keyboard because they are used to the way the keys are weighted, now they can just plug in and record. No more searching behind things for MIDI inputs :-)
