This type of tool is essential when you have more than 4 gnrateurs audio and / or multi-effects driven by noon.
I do not use SMPTE.

UTILIZATION

Drivers (W2K) trs stable although rarely updated.
The interface has not saturated but sometimes encounters a problem at boot (USB signal is not recognized). Just stain the rack and on again to return everything to normal.

OVERALL OPINION

I use this interface from 2 years ago, with two successive informatqiues config.
Too bad the 8 MIDI in / out either in front (I prfr derrire all connections!)
Too bad there is not some MIDI ports supplmentaires.
Good interface, solid, srieuse, and slightly less than the competition CHRE (the date when I bought it).
