David Martin Frank (born November 13, 1952) is an American music producer, composer, classically trained pianist, and founding member of the 1980s R&B group the System. Yamaha Music calls him "the founding father of electronic R&B." 　　Upon graduating from Berklee, David began playing in bands around the Bostonian metropolitan area. The bass player in one of such bands exposed him to an ARP Odyssey synthesizer for David to play. The new sounds intrigued him so much that, borrowing the money from his Dad, he bought one for himself the next day. When Frank moved to Manhattan to try to become a session musician, he began playing at weddings while amassing more keyboards including those manufactured by Oberheim: the OB-Xa polyphonic synthesizer, the DSX sequencer and the DMX drum machine which in effect made him a one-man band.
