Alesis IO Dock
This one’s aimed at the pros who want to use their iPad with pretty much any audio gear. Alesis IO Dock works with MIDI controllers, video projectors, speakers, PA systems and tonnes more, alongside any app you chose to use.
Handy XLR and 1/4in inputs mean any mic you might have kicking around should do the trick for your vocals. Record guitar – and whatever else lying around – direct to the iPad thanks to this professional grade kit worth £140.
