** This app does not sample any PCM-based synths, including Roland or Korg digital keyboards. Additionally, this app does not have any business relationship with Roland, Korg, or any other 80s/90s Digital Synth manufacturers.

*** All app sounds were created by pure analog and fm synthesis. We took these new sounds. Stacked them. Flipped them. And,  processed the heck out of ’em. Resulting in a beautiful new sonic palette for you to enjoy.
