Is there a way to edit one of the Theremini’s presets to
sound anything like the supersaw waveform from a Roland JP-8000..?
(I am waiting for my instrument to be delivered but am already flowing with ideas.)
Hi Ether_Magick,
There’s an official “Theremini Advanced Software Editor” iPad app from Moog: https://itunes.apple.com/ca/app/theremini-advanced-software/id929763039?l=fr&mt=8 that will likely interest you. See as well the third party Theremini presets on http://www.animoog.org/theremini/
Hope this helps, enjoy your Theremini
