Wireless Control for ALL Your MIDI Gear!

Bring your MIDI gear into the wireless age with the M-Audio MidAir system. Comprised of a portable transmitter and receiver, the MidAir allows you to wirelessly transmit data from any device that outputs MIDI data - keyboards, drum machines, electronic drums, and more. Just plug the battery-powered transmitter into the MIDI Out port on your controller of choice and connect the receiver to the MIDI In port on the device you'd like to control, and you're set. As a 2.4GHz wireless device, the MidAir enables you to interface MIDI hardware at distances up to 30 feet with the same feel and response as a wired unit. The MidAir receiver includes a USB port and functions as a class-compliant 1x1 MIDI interface, so you can also wirelessly control soft synths from your favorite MIDI controller.

Quick, simple, and easy!

We had no problem hooking up the units and getting them functioning. The worked well for tracking MIDI signals from keyboards into ProTools. I will definitely be using them again.

MIDI Clock for the Band

by Reid from Atlanta

For live playing at our church on a large stage, we've been searching a way to synch Ableton's MIDI Clock option to all the MIDI capable instruments on stage (keys arpeggios, guitar delay pedals).

We tried MIDI-to-XLR hardwiring, but ran into interference issues since the cable runs were over 300', down one snake and up another.

So we gave one MidAir a try as an experiment. WOW! It worked!

Gonna get a couple more MidAirs for the rest of the players. But we will need to get a MIDI Thru splitter to make that happen (1 in, 4 out).

The biggest downfall - and the only reason I didn't give the product a 5 star rating - is that the transmitter does not come with a power supply.

There's two units (one transmitter, one receiver), but only one power supply. Sure, you can use batteries with the transmitter, which is perfect for Keytar stage roaming. But for our installation we had to go to Best Buy to get a universal adapter for the transmitter, 'cause it was chewin' though AA's. close [-]

Wireless on stage

If you own a remote keyboard (keytar), You have to have this! I now can go out off stage to check the mix, run around the stage and not worry about a 50 foot midi cable. The range is around 30-40 feet... read more [+], but most bar stages aren't that long. Great piece of gear and very cool. close [-]

I FINALLY GOT IT TO WORK

by Greg Husted from Las Vegas

After a week of trying to get the transmitter and receiver to sync, all of a sudden they did, and has worked fine since. I use a Roland keytar and the range is as advertised=30ft. I have had problem... read more [+]s controlling Roland modules. If I use too much mod or pitchbend the Fantom XR and XV5080 will switch to sequence template mode during a performance!? The keytar was set not to send any changes. The modules were set to receive changes on another channel. Also, they sometimes change modes when I turn the transmitter on. I hooked it up to a laptop and no problems.(only one play mode!) I only use it on 2 tunes a night in a 6 night a week show (I turn it on before 75 min show) and change batteries once a week-so I guess battery life is not affected much when you're not sending data.(and thus, can't speak about the many complaints of short battery life-the performers who rely on other battery packs for the entire show have theirs changed every other day) I use it to drive Ministry of Rock, Massive, and Xphraze, and have had no drop outs when using plenty of PB and mod. I would not recommend this unit for Roland modules. close [-]

Not very good

by David W from Washington, DC

I bought this thing to hook up to my midi wind controller so I wouldn't be tethered to my midi gear, but it has two very big problems.

1. This thing eats batteries faster than any wir... read more [+]eless device I've ever seen. I have a wireless audio transmitter for the EWI as well and I can get a good 10 hours from a full battery. The MidiAir only gets about 3 hours. May not seem like much but it gets expensive after a while.

2. The range is very poor. I've tried using it in many different settings all with the same result. Even with no obstructions between the transmitter and reciever you can't walk more than 5 feet away from it before you start to notice dropped notes. I was playing four feet away from the transmitter and someone stood in the middle and I got dropped notes.

I should add a third point. After less than a year it stopped working altogether. Avoid this thing. close [-]

Without a doubt Sweetwater has become my " go to" place for all my musical needs. EXCELLENT JOB GUY'S! Very fast delivery.
