A bit on the pricey side, but you can't go wrong

It's a top quality MIDI-USB interface, well build and simple to set up: I simply put the CD it came with in my PC (Windows 10) and run the driver installation program.

Then I connected my piano (Korg D1) and it worked flawlessly without any noticeable latency problem.

The only negative aspect is the price, as this cost as much as two of the cheaper models.

Still, I gather that the reason of the pricetag is due to a proprietary tecnology being used by Roland to reduce latency, so if you want the best, this is the way to go.
