Tonight is the night, a rare rehearsal (in a great space) and I'm bringing the whole PA rig (mains, sub, Mackie DL1608, stands, mic's, cables). I hate to think I'm paying for a great room that already has killer gear when I really could rent out someones garage for this one, but it needs to be done We will be testing incorporating backing tracks so getting proper IEM mixes is of utmost importance tonight. The one factor I can't control is drum micing - I guess tonight I need to decide if I'm going to go kick, snare, overheard or just kick snare... I suppose the proper way to build the IEM mix is to get everything into the board at correct levels, then work on a BASIC IEM mix, then customize everyone's personal mix and snapshot it. It would be amazing if we can get this done (which I think we can, we have already done several gigs with IEMS) but get levels really comfortable. Then all I would have to do is recall the snapshot and bring up the Master Fader for a show... EDIT: If my players bring their iPads I will setup the configuration so they can control their own IEM mix as well, but I need a very good snapshot of general settings first.
