This major upgrade of NI's legendary virtual analog synth comes with many new functions and improvements.

"A new oscillator technology provides a decidedly more brilliant, and warmer sound. Additional new features are a high-pass filter mode, invertible filter envelopes and an LFO-envelope-retrigger option. The PRO-53 is now also equipped with a MIDI Learn function for fast and convenient integration of hardware MIDI controllers and the option to load controller maps. The PRO-53 comes with an optimised graphical interface as well as 64 new sounds that take full advantage of the extended functions."

The recommended retail price is £129.99 inc. VAT.

Registered PRO-52 users will soon be able to upgrade for free through NI's website. Already there are an additional 16 presets available for download once you've registered your update.
