Saurus can do 'analog' as well as 'modern' sounds. What kind of sounds it does depends on what the sound designer does.
A good place to start are the 'Analog Poly' and 'Analog Mono' patches within the Tutorial patch category.
Here are some tips for 'analog' sound design:
- Osc 'DRIFT' should be on
- Osc 'PHASE' must be set to 'free and global'!
- No Reverb, Delay, Boost and stereo unison. These effects are too 'modern' and didn't exist in the 70s in such a high quality.
- Use a little 'GLIDE'
- Use 'SOFT' resonance to simulate filter saturation on high resonance
- Route 'CONST' as source to 'Noise' as target in the mod matrix to add some noise
- For more instable oscs use 'WhiteNoise' or 'PinkNoise' as source and Osc1/2 fine as target in the mod matrix
- For more filter saturation use 'CONST' as source and 'Osc1/2 Vol' as target in the matrix
- Use a little 'DRIVE' for a more saturated sound
- You can get additional instability be routing 'VoiceOut' as source to 'Osc fine' in the matrix
- A little 'TUBE' can make it sound more vintage
- Use short attack times instead of 0 attack times for a more juicy sound
- Use 'TONE' settings from 0 to -100 for a warmer sound
