"it delivers a lot of options, very respectable audio quality and adds little in terms of weight or bulk to your iPad or iPhone-based mobile recording studio" and make sure you check out their step by step video!
MusicAppBlog, the site for mobile music making and production, have not only put together an in-depth review of iRig PRO but have also produced an excellent 5 minutes demo video to accompany it.
Here are some of the comments from reviewer John Walden:
"In addition to a high quality instrument input, you also get a microphone input with phantom power and MIDI in connectivity. In essence, the iRig PRO is an ultra-compact audio+MIDI interface aimed squarely at the recording iOS musician."
"I tested the unit with a range of microphones and I have to say that, on the whole, I was very impressed with the results."
"The iRig PRO doesn’t feature audio outputs. You simply use your standard headphone jack output from your iDevice to feed either your headphones or a set of powered monitors (or perhaps a PA). In practice, this works absolutely fine."
"the combination of audio+MIDI in a single device is most definitely a big plus, as is the capability to record anything from a guitar up to a studio-class condenser microphone."
"as a mobile solution for the iOS musician, the iRig PRO really is an excellent all-round solution."
John closes his review with his verdict:
"From a design perspective, I think IK Multimedia have got this just about spot on ... with a good balance between features, audio quality, portability and price, if the iRig PRO doesn’t sell to iOS musicians by the bucket-load, then I’ll be very surprised!"
To accompany his review, John has prepared this very informative demonstration video:
