The SynthStation app gives you three fully editable multi-oscillator virtual analog synthesizers and an onboard drum kit. Perform live using real synth-action keys or compose on the go with the onboard step sequencer and upload the files to your computer for further tweaking. You can even plug SynthStation 25 into your computer via USB and turn your iPhone or iPod touch into a MIDI-controllable sound module.  Produce music anywhere with SynthStation25.
