1x1 midi-usb cable with a jack IN and OUT outlet, connects to a PC via a USB port, plug and play recognition in Windows XP, 16 MIDI Channels IN & OUT.
I bought this product Thomann cheap for my ZOOM G9tt connected to my computer.
The latter is newer (Pentium 4 duo, ram 1024 ...) and it only recognizes the audio interface of this product, not MIDI! so it does not work on my computer!
on the other hand, it works perfectly on my wife's laptop = egg saved from not having purchased anything in light of previous opinions!
Positive and compact design = no fun.

UTILIZATION

For drivers, I would short = nonexistent! nothing to configure.
For the site builder Swissonic = as absent (= one falls back on the site Thomann) so no update possible.
The software I use is that of Zoom G9.2tt Editor Librarian who used to set and save these patches on computer!
Well after a time it works, nothing to say, the data is transferred properly.

OVERALL OPINION

I for a week, happy not to have bought for nothing! Apparently, its operation depends on the computer configurations?? For now he fills his role so I will not have much "down" but I do not recommend it.
It is better to add a few dollars to buy a midi-usb interface more serious, with drivers configured.
Poor value for money + + + cheap for sure but also not terrible.
