"The PRO-53 carries on the tradition from the legendary days of vintage cult synthesizers. This virtual instrument, fashioned after the Sequential Circuits Prophet-5, provides the sonic properties of the unique originals while meeting the practical requirements of the present day."
"With the PRO-53, the third generation of the virtual analog classic is now available. The synthesizer emulation has been vastly improved by a new oscillator technology that offers an even warmer and more brilliant sound. In addition the sonic possibilities have been expanded even further with new features like a high-pass filter mode and an invertible filter envelope. The control surface was also reworked and now shines in a whole new light."
