Meditation: Pulse and Separation was written using samples taken from David McIntire's Putney Etudes Nos 1 - 6. These Etudes explore various sound possibilities of the EMS VCS3. I extracted 60 samples from these Etudes and mapped them onto my keyboard using Pure Data as the virtual sampler. In this way I re-created David's synth he improvised on for his original works. I then recorded many improvisations of my own, mapped those recordings back onto the keyboard in another PD patch, and finally recorded the final "performance" of these improvisations.
For a copy of this "re-created" synth using David's samples you can contact me at firstname.lastname@example.org and I will send you the PD patch and samples.
