In summer 2022, we ran a kickstarter to reprint Allen Strange’s book Electronic Music: Systems, Techniques and Controls. For information on Allen Strange, his work and legacy, please visit allenstrangeelectronicmusic.com. The kickstarter raised over $266k, and you can read more about it in the article TMU professor raises nearly $270,000 to reprint music theory textbook.
