For anyone actively involved in synthesizers be it modular,rack mounted,keyboards,plug ins/outs new or vintage on any level will find this doc amateurish and incomplete. Hard to believe that this film was red lighted and budgeted with such an unprofessional script and production values.
There are HUGE gaping holes and flaws in the timeline of the development of synthesis.
Not one mention of The ondes martenot,Mellotron, Erkki Kurenniemi - who always forgotten in these discussions, Raymond Scott, Daphne Oram,EMS synthi, Delia Derbyshire,The BBC radiophonic workshop,Kid Baltan and Tom Dissevelt and the Dutch hardware inventions/ contributions, Tod Dockstader & James Reichert and all of the soviet synths etc.
Just shameful omissions that exemplify a hasty hack job created by someone's trust fund.
If you have no knowledge of who Bob Moog or Don Buchla are then I suppose it is a very primitive poorly constructed primer,beyond that there is not much here for the real heads AVOID!
