What's new in Saurus 2.6?


True analog sound with state-of-the-art features!


Saurus2 can do an extremely authentic emulation of analog synthesizers. It covers all important aspects of the most famous and expensive analog synths, but without their disadvantages.

Saurus2 comes with a clear, easy to use interface. It offers a larger sonic range and a more flexible synthesis engine than conventional substractive synths. Saurus2 offers quality high-end sound, but without placing heavy demands on your CPU or budget. At the heart of Saurus are it's top-notch oscillators employing our True Analog Modeling Technology ™, which produces a warm characteristic sound of the hardware units from the past. With  PWM, Sync, AM & FM an extremely broad range of sounds can be dialed-in. Saurus offers a selection of both standard and exotic oscillator types from hard-to-get analog synths. Finally, true analog sound no longer requires any compromises!


Arpeggiator & Gate


We created an arpeggiator that doesn't just offer the basic note step functionality. It takes the concept further by adding features such as custom patterns, chords, swing and per step velocity. Your arpeggio sequence can be as simple or complicated as you wish.




True analog sound requires an excellent filter that's capable of sounding both lush or screaming when overdriven. However, analog filters are far from perfect. They suffer from distortion, noise, phase shift and self-oscillation. Exactly these imperfections add this magic character, which is missing in digital filters. That's why Saurus comes with a filter section which models the most famous analog filters. With precisely modeled non-linearity and self-oscillation they sound and behave exactly like the analog circuits. To top it all off the filter section also includes FM, feedback and an analog-modeled distortion for that little extra grit.


Modulation & Effects


By using drag & drop or the matrix, Saurus allows you to connect dozens of modulation sources to sound parameters. Modulate almost any parameter up into the audio-rate speed. We've also included midi-learn, so assigning CC's is as simple as a right-click.

To compliment its sound, Saurus features various classic effects such as 4x unison, chorus, delay, reverb and tube amp. All effects offer the highest quality possible.
