SYNTH STATION is the first iPhone/iPod touch app from Akai Professional. This virtual production studio gives you three virtual-analog synths with three oscillators each and 50 drum kits with a sequencer. You can create exactly the tones you like and then use the filters, oscillators, and arpeggiator to shape, texture, and add rhythm to your sounds – just like a physical synthesizer. SYNTH STATION has effects with easy-to-use controls and an on-screen keyboard, plus it’s seamlessly compatible with the iPK25 docking keyboard controller.

Akai, I’m hereby formally letting you know that I am waiting for the Andriod version!!!
