Mark Mosher improvisation on the Saurus virtual synth

April 12, 2012 · Posted in Uncategorized 

My Colorado based electronic music friend Mark Mosher, sent me this nice improvisation that he has made on the Tone2 Saurus synth:

“It’s gorgeous. Checkout this improv vid I made with Saurus.

About the video:

This is single patch improvisation recorded in one pass with no edits using Tone2’s virtual Synthesizer Saurus. A single instance of Saurus is used with no other effects or editing other than what is built-into the synth. I’m starting with a factory patch in the “Lead” bank called “1970s Soloist H”. I only touch the computer once during the performance in the middle to turn up the gain in the mod matrix so that LFO modulates pitch.

Prior to recording I mapped all sorts of parameters to my Novation Remote SL MK II Keyboard.

– XY map to Filter and Rez
– Bank 1 of the top 8 knobs are mapped to filter parameters and OSC Balance
– Bank 2 of top 8 knobs are mapped to effects parameters
– Bottom row 8 knobs are MIDI mapped to Oscillator noise type AM/FM, LFO Speed, Glide rate
– The first 4 sliders map to the volume ADSR
– The next 4 sliders map to filter ADSR

I used my projector to paint my wall with Saurus to the knob movement you see on the wall is in real-time and corresponds to my controller movement.

From our original post on the Saurus:

Tone2 has released a new software synthesizer for Mac & Windows, Saurus.

According to Tone2, Saurus is ‘not just another synthesizer with character, but one that truly represents the analog sound.’

Here’s what they have to say about it:

We carefully measured and modeled the circuits of many classic performance synthesizers, including even single capacitors and resistors to provide an extremely accurate analog model, faithfully capturing the spirit and character of these old machines. All without placing heavy demands on your CPU or budget.


  • True Analog Modelling Technology
  • High-end sound quality
  • Low CPU and high reliability
  • Easy-to-use interface
  • ‘Unique sounds which no other synthesizer can create’
  • Huge sonic range
  • Flexibility, expandability
  • Ships with 563 presets from 21 sound designers


  • Covers all important aspects of traditional analog synths
  • Mono, Legato & Polyphonic modes employing analog voice management
  • Two Syncable Oscillators and two Sub Oscillators
  • Not just standard waveforms but also a large number of exotic ones
  • Pulse Width Modulation and Oscillator Sync applicable to every waveform
  • Oscillator Drift, Phase and Noise Modulation controls
  • Noise FM, AM and Ring Modulation for Oscillators
  • Analog filter with self-oscillation, nonlinearity, 6 filter types, FM and feedback
  • LFOs and modulation capable of running at audio-rate
  • Arpeggiator with extensive configuration possibilities
  • Flexible Modulation Matrix with new features, including a filter
  • Programmable gate
  • 4x Stereo Unison modes with spread and panning control
  • Analog modeled Distortion and Tube amp
  • Optional Psycho-Acoustic processing
  • High-end quality Effects

Tone2 Saurus is available now for US $119. See the Tone2 site for details, audio samples and a demo version.
