Over the next year, with encouragement from Myron Hoffman of the University of Toronto, Moog and Deutsch developed the first modular voltage-controlled subtractive synthesizer.
Tokom sledeće godine, uz ohrabrenje Majrona Hoffmana sa Univerziteta u Torontu, Moog i Deutsch razvili su prvi modularni naponski kontrolisani subtraktivni sintisajzer .
