4in/4out MIDI Interface - DriverGenius USB MIDI Interface with Standalone MIDI-Merge 2in/4out (USB Mode, MIDI Thru Mode, MIDI Merge 2in/4out)

It works as promised, but when playing live 88-key keyboard controller into my laptop, it seems to lag a good 600ms which is very noticable. I'm disappointed. I'm sure for playback to a whole rack of gear it would be fine, but live monitoring is not up to par.

The media could not be loaded. Received non-functional interface. DriverGenius support (Katie) was reluctant to believe that I was operating it correctly.I don't believe she read my walkthrough of the issue in the email because she instructed me to do exactly what I wrote that I had done.I will update when the stonewalling ends. Not worth the hassle for a $20 item, but people need to be aware.Edit: Purchase refunded without return. I will give the benefit of the doubt that the perceived snark and rudeness was due to a language barrier. Added a star for resolving the issue before the review went live.

Works Perfectly, I can n now have all my midi instruments plugged at once.
