Korg's latest iOS offering is described by the company as a 'mobile synth collection'. The app houses 15 virtual synths and drum machines, or 'gadgets' as Korg calls them, each of which is roughly based on a classic hardware unit.
Multiple gadgets can be loaded into a project, each devices offers its own sequencer, and there's a multitrack arranger and mixer, which allows the creation of full tracks from within the app. The sequencers and keyboards of each gadget can be locked to a set key too, which improves the workflow for those with a limited knowledge of musical theory, and generally helps circumvent the difficulty of playing melodic parts using the sometimes fiddly touchscreen keyboard.
Gadget is core MIDI compatible, and the recent addition of Audiobus compatibility is a major added bonus. The only real downside to Gadget is that it's fairly processor hungry, meaning that those with older iOS devices may struggle to run more than a few synths or drum machines at once, particularly when used in conjunction with Audiobus.
