I play in a four piece rock cover band and was looking for a better way to mix shows. I wouldn't call myself a sound guy, but sound guys I've used in the past have told me my mixes are great since I started running it myself. Prior to purchasing this I've been playing with the ipad app demo on my ipad 2 for a few weeks and then downloaded X Air Edit for the PC mid week. I noticed on a Tuesday night this was available on the Sweetwater site and emailed my contact Anthony who happened to be working the late shift. It was shipped on Wed. and received it 1/2 way across the country on Fri. I spent the day fooling with it trying out the effects and presetting what I thought would work for my gig on Saturday. I'm the guitar player, but have been doing the sound lately for the band using a 10+ year old Behringer board. I forget the model. I run this with newish JBL PRX712 and 718XLs. The thing is small and could likely fit in your old Scooby Doo lunch box. I just showed my age. I brought my laptop an ipad to the gig. I never once lost a connection to my laptop using the built in wifi, but be sure to set your sleep mode a little longer so it won't lock you out or go black during the set. The ipad worked fine and was even more useful for quick changes, but as some others have mentioned it did lose it's connection a few times per set. That really wasn't an issue for me since the unit still works during that time and to get it back connected took 5 seconds. I would end the app, not by closing it, but by swiping it and then launch it again. I was back and running literally in seconds. Not a biggie since I know that will likely get fixed and I can't make that many changes during the song anyway. I'm busy playing guitar. I'll likely just gig with the ipad going forward after a few more gigs with the added laptop as a backup and tweaking my scene. (My ipad is also from work and has some pretty tight security profiles on it so that could my issue too, but seeing others had the same issue I doubt it's just my ipad.) Comments I heard were all positive and even non musicians came over said how great the mix was and crystal clear the vocals sat on top. Others said the lows were strong and punchy, but not muffled. I didn't even eq the mains either so the JBLs are pretty awesome, however the channel eqs were used on every channel, but nothing major. X Air Edit PC - First be sure to update the Firmware to the latest version. Using the app wasn't hard to figure out since during my wait for it I was able to demo the competitor's versions from QSC, Presonus. I like the QSC interface a lot, but didn't really need the recording features. It did have the built in screen and wifi, but then again I could just buy another ipad for that price difference between the XR18. This was definitely closest to the Presonus look and feel. I know this is just the beta 0.5 version so I didn't expect much. I was a little upset by this since Behringer was talking up this product as new and innovative. Plus, a non beta version should be available from day one, but I suppose demand got the best of them and they sent the product out. Besides that, it really didn't matter. It worked and worked great and it's half the price of others. I did have an issue where the effects weren't working after me playing with all types settings and whatnot. I called Behringer and they picked up and answered it within less than 5 minutes total. I just had to reinitialize the mixer from the app and it's worked fine since. I likely changed something I shouldn't have, but the point is Behringer helped and in a flash. While it's not the prettiest interface I give it a bi since those are easy fixes that I'm sure will come. It could use more areas to right click, hover or pop up areas for seeing numbers/value change etc, but that did not limit me at all. The colors and numbering on the faders are pretty bad and it was hard to set gain levels. I made adjustments from the ipad afterwards since that looks better in that area at least. Needs sub groups and/or DMAs, but that isn't crucial for me since really it's only 16 (18) channels anyway and I use 11 of them. I'm sure they will come. The Pres seemed as good as any I've used. Overall main out volume seemed lower than my old board, but to be fair being the guitar player I didn't get a whole of time to play with the master after we started. Thee Gate and Compressor default settings seem fine with a few adjustments mostly on the threshold. The effects seem great and have enough flexibility and character that you'd never be hurting for quality sounds. Needs tap delay capability though. Plus you can't save your effects for using later unless it's just part of your scene. I'd like to recall a preset of my own one day. Pay attention when saving scenes and channels since you need to be in the right screen for it to want to save or open that file type. That took me a while. Just be in a certain channel if you want to save or load a channel and not if you want to load a scene. Eq - Again this sounded fine, but tweaking the setting could use help, whether you are dragging lines in the graph or typing in numbers. There are no sliders and sometimes you can type and tab to the next, but other times you need to hit Enter. That's not a big deal, but led me to making quick changes from the ipad during the show more often than the laptop. Ipad App - As a controller to connect to the mixer it worked fine, but if you had to set up a gig from this you'll be hurting since you can't access all the effects and the eq is lacking the graphics. However, Behringer said yesterday they submitted the next version to Apple and it will likely be available withing a week. I bet those are added. If you know how to use the ipad app or X Air Edit you'll easily adapt to the other. I know it's probably not meant to be the main tool to set up a scene, but it would nice if you could download a scene or channel in a pinch from email, Dropbox, etc. USB - I tried to use Cakewalk Sonar to record from the mixer before the gig, but couldn't figure it out. I have a feeling I need a driver that hasn't been made available yet. I wonder if you can record and use Edit to mix at the same time on the same computer. Aux In 17/18 - I wish I could just play music wirelessly from a computer or iphone rather than physically connecting, but you can't do that on traditional boards anyway. Maybe there could be away at somepoint through the wifi or Bluetooth add-on?!? Midi - Haven't thought about it, but maybe it's something the singer could use down the road to change effects for volume levels?!!? I'm not sure what's its for. Overall this thing worked perfect at my gig and any small hiccups were to be expected being so new. I never had any catastrophes and can't wait until next week where I'll just recall the settings I saved at the end of the gig and take a breather before we start. I'd certainly recommend this to others as long as you don't mind a new way to do things. If someone has never used a DAW you may have a rough time and would likely take longer to feel natural with it. It did feel strange last night when I needed to make an adjustment and I wasn't sure where to go and then realized my ipad was there next to me on the JBL sub within reach. The quality of sound is there and will only get easier to use. It's exactly what I hoped for and expected.
