I was looking for a USB MIDI interface for my POWERBOOK4 12''...
One in and one OUT.
I use it mostly with my Pure data and interface Num / Ana / midi
to control my hardware synth live or on audio device.

UTILIZATION

The drivers are stable, no problems so far.
I use it mainly with Pure Data.
Not a problem of saturation of the Midi interface!

OVERALL OPINION

I've had six months
I have not tried other interfaces before buying it, it does not have many competitors in CME and edirol I think.
The specifics I like most sound:

simple, plug and play, something I like animals but led that indicates the midi in and out is prtic, it would in a jacket pocket.

Minimum:

The length of twelve o'clock in and out far too long ... but hey it's my personal opinion.

Value for money very good!
I would do is choosing without hesitation!
