As for the latency problems in the reviews, get ASIO4ALL, latency has not been a problem for me with ASIO4ALL

Unfortunately, the latency of this product is TERRIBLE

Some programs have drivers for these built in, and it's not too hard to install a generic one, of course every time you add another element to the data stream your more likely to have lag (latency issues)

The product works but the latency it takes to send the midi notes from the old keyboard to my computer is ridiculous

I have a Yamaha YPT-310 keyboard, and the latency was terrible

If it does work, there is horrible lag (latency)

The latency is so bad, I am several seconds behind the tune.

, has a little latency, not too bad.

Although it triggers properly, serious latency make it totally unusable

Terrible latency

There was no noticeable latency and it worked fine on my Mac (10.6.8)

It does not work as advertised, nor does it work as per the accompanying instructions

Works as it says it does, nothing fancy, but great value for the price

I tried this converter with two midi keyboards, as well as, a midi controller with sound module on three computers

Both work just as they're supposed to.

Works perfectly -- records piano keystrokes in my audio editor (sold separately) and plays them back through the piano, as well as through the speakers of the computer.

Going through and playing music, you'll have a very loud "E" play every time you press the pedal
