X18 : great for rehearsals

I use the x18 for mixing and recording band rehearsals, and other general multi-track recording. The sound quality is fantastic, and beats my TC Konnekt 24d firewire soundcard.

At rehearsal everyone uses their mobile phone to control personal foldback/headphones mixes and we get a full multi-track recording as a reference for later on a laptop.

The Windows, Android and iOS control apps work really well, and the wifi connection is glitch free.

The FX are quite good quality, the compression in particular is very helpful for the singer, who has a fairly dynamic voice.

I guess only real con is the lack of hands-on controls, but at this price-to-feature ratio you can't complain. There is a matching Behringer control surface if you must have hands-on control.
