Creating sounds with time-varying timbre, on your mobile device. KORG iWAVESTATION - A wave sequence synthesizer for iOS. The WAVESTATION synthesizer went on sale in 1990. This instrument featured an advanced vector synthesis system which created new sounds by combining and connecting multiple waveforms; it provided a mix/morphing function that let you use a joystick to change the balance of four oscillators, and a distinctive wave sequence function that allowed you to place waveforms in a desired sequence to create sequence patterns. To this day, it continues to be considered a legendary and still-unique instrument. Now in 2016, the WAVESTATION has been reborn as "KORG iWAVESTATION," an app for iPad/iPhone.
