When it was first released in 2005 ‘BLUE’ already reflected Rob Papen’s cutting-edge, creative, and — most importantly — musical approach toward developing virtual synthesizers. Rob Papen himself called it ‘Cross-fusion synthesis’ because it covered both Subtractive and FM synthesis in one creative concept.
With its successor BLUE-II, the ‘Cross-fusion synthesis’ was also expanded with a creative range of samples and the highly versatile XY pad.

The concept for BLUE-III still remains true to that ethos with even more added sound dimensions and features to its extended name. Firstly adding our own take on ‘Karplus Strong String Model Synthesis’, new ‘Waveforms’, new ‘Filter types’, a new range of creative ‘built-in Samples’, and lastly the option for you as a user to load up to 6 samples inside each Preset.

BLUE-III’s GUI has received an overhaul including many different sizes, the XY pad is now always on the front panel. The audio engine has received DNA from our virtual analog synthesizer B.I.T. resulting in unsurpassed audio quality.
Lastly, of course, this amazing instrument is shipped with 5000+ Presets by Rob himself and well-known industry sound designers.

BLUE-III is a phenomenally powerful virtual instrument to behold and represents an amazing journey into ‘Cross-fusion synthesis’!
