This month Future Audio Workshop went retro, as we dusted down the original Sequential Circuits Pro-One synthesiser that we used to model Circle’s filter section and went about recreating the original factory patches which were contained in the original Pro-One owners manual. This process involved first creating a patch on the Pro-One, analyzing the sound using frequency analysis tools, then matching the settings and tuning the sound so that they matched perfect between Circle and the Pro-One. This authentic analog sound bank for Circle is free to download for everyone.
