Thrubox. 1 Midi input and 3 Midi outputs.
9-volt battery or PSU operation (battery in my case).
I read the box switches off after a certain time without signal input... The manufacturer indicates a one-year long battery life.
Black rugged plastic housing.
It routes the Midi input signal to the 3 outputs... it's magic^^.
It helps me control 5-6 sound generators/drum machines synchronized with Ableton under Windows XP.
The Philip Rees V3 isn't bigger than a pack of cigarettes (2.3" x 2.7" x 0.9") and makes a very good job. I didn't feel any Midi latency.
I chose the product because it's simple and cheap. The price was ridiculous,
thank you Philip! I would definitely buy this product again... or I would try to find a v4 or v8
