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

Saurus 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.
Saurus comes with a clear, easy to use interface. It offers a larger sonic range and a more flexible synthesis engine than conventional subtractive synths. Saurus 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.

Filters

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.

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.

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.

Microtuning

Saurus3 offers 7 different microtuning-modes that can model analog oscillator-drift. Furthermore, the engine can slightly detune certain voices to make your chords sound fatter, harmonically rich and warm. Unlike with conventional synths, our innovative microtuning is not limited to the usage of a certain tonality. Saurus is able to analyze your melodies in real-time and enhances your chords automatically. It 'just works' - you do not need to take care of anything.

User-friendly copy-protection: No cloud, no dongle, no need to be online.

This is an absolutely fantastic synth with lots warmth and character.

The reason why I gave it 4 instead of 5 stars is because version 3 doesn't introduce enough changes to warrant a major update. It feels more like V 2.7 rather than a full blown V3. There are many requests and suggestions from users on the Tone2 forum that have gone unaddressed in this update.

Still the synth sounds great, (just as the previous version did) and it's easy and fun to program too.

What an amazing synth! Just rediscovered it after not giving it much attention for a while and i must say it really impressed me with its truly analog sound. I used to go to diva for those flavors but now i found out that Saurus sounds even better. Its a shame that the interface looks a bit dull (as tone2 website) but the sound kicks a55. Actually i believe the reason it isnt a very popular synth is because of the interface being kind of weird in color/shadows and proportions. Actually all tone2 synths suffer from this, i hope they will get a more inspired designer soon because design affects perception and lots of people are influenced by that.

Sound - 10/10

Ease of use - 8/10 (the arp/matrix screen could have been bigger)

Interface - 6/10
