[LAU] USB MIDI controller

>the midi signal has the same quality, no matter where you save money.

That's not true, the interpretation of MIDI signals could suffer from
bad designed MIDI interfaces much, e.g. in regards to the used
opto-coupler and the fine tuning, as well as they could cause ground
loops, but indeed, all Behringer devices I ever used, had MIDI
interfaces that worked without issues.
