A band I work with recently upgraded their sound system with a sound board that allows for mixing on an iPad. (...really any tablet with connectivity.) These have been out for a while and several companies have them, but I had not had a chance to hear one in action. It was great how the sound guy could move around the venue making tweaks in volume and eq without being tied to one spot.

He really put it to work standing at the back of the room, in front of the stage, and everywhere in between. In no time the PA sound was fantastic.

We didn't get to it that night, but individual band members can have access to their own monitor mix using their smart phones. Some may not want to do that, but it's good to know they can.

When you play out you need to sound as good as you do on your recordings. Good monitoring allows you to really hear yourself and give a better performance. A good sound guy is important to present you as well as the circumstances allow. This kind of system makes his (...or her) job a lot easier.

Before too long you may need this just to keep up with all the other bands.
