The EX-5 features a unique Extended Synthesis system which incorporates a number of the most advanced tone generator technologies currently available...plus a full-featured sampling system. It offers a Four-Element Voice structure which allows for up to four independent waves from any of the tone generators. The tone generators implemented here include AWM (Advanced Wave Memory) Synthesis, AN (Analog Physical Modeling) Synthesis, FDSP (Formulated Digital Sound Processing) Synthesis and Virtual Acoustic (VL) Synthesis (http://www.vintagesynth.com)
It really doesn't matter that probably most of you (me too) don't know Japanese. Watching this guy playing some random things based purely on inspiration is entertaining and inspirating itself.
