«  A simple and effective interface »

I needed a MIDI / USB drive for Addictive Drums via my Roland electronic drums. I chose this product by chance (and also because I trust the products relativemment Roland / Boss / Edirol.

I only needed a single MIDI In and MIDI Out, so I opted for the smallest model Edirol (other offering several MIDI in and out).

UTILIZATION

After installing the driver, plug the device, it configures your PC and other software (drummaps etc ...) and everything works parfaitemment. Latency is absolutely undetectable by ear.
I use it all with Addictive Drums Cubase and Windows XP Pro. I have tested equals with friends in Live, Nuendo and sequencers in Windows Vista and Seven, each time no worries.
Stability is exemplary. I had no crashes or bugs.

For those who have a significant distance between their MIDI and their computer equipment: attention to the length imposed by the cables included in the box.

OVERALL OPINION

It's been eight months since I use it and I am very stisfait. The price may put off a bit initially for a simple MIDI / USB (other brands offer less expensive) but it's really a great product. Did not test the interfaces from other manufacturers, I can not compare
but we must admit that it fulfilled its role parfaitemment)
