Jonny Trunk has released an iPad version of the VCS3 synthesizer, one of the first portable synthesizers to be developed. Made in 1969 by Peter Zinovieff's EMS company, the VCS3 was used by Jean Michel Jarre, Brian Eno, King Crimson, Pink Floyd, The Who, Gong and others. Trunk writes: "A few years ago I thought the idea of a VCS3 app was a good one. So I got permission to get one made. It’s taken ages. Here it is. It's awesome, extraordinarily deep too, and with features from the suitcase Synthi too. And hopefully updates will be available with Radiophonic patches etc created by original Radiophonic superstars."
