If anything can be said about the Evo is it's powerful. If you compare it to other synthesizers its features really outdo almost any other mono synth on paper: 4 oscillators. Nearly any configuration of modulation. 4 LFOs. Parameter Envelope. On board effects. Split filtering. Built in sequencer assignable to any parameter. However, it doesn't sound quite like anything else i've used - the quality of the sound. Not sure why. Maybe it's the analogue to digital conversions that are happening? Some people say it doesn't have low end, some say it doesn't sound warm. Not sure about this. I will say it does takes me longer than other synths to get the sound I want out of it. It does tend to have a... sterile sound somehow even though I can also describe it as aggressive and harsh too or even warm. I know I'm contradicting myself. But, this synth just isn't so black and white. Great for powerful leads. Great for ambient stuff too. Great for almost anything really. It's nice to screw around with it for hours and see where you can push synthesis to - that's for sure.
The desktop Evolver is not as punchy, precise or characterful as the famous vintage synths. Its UI is fiddly. Nevertheless it's great fun due to the internal sequencer, the digital osc combined with DCOs, the internal fx and the modulations. Looking from this angle it's yet quite characterful. The sequencer can modulate its own tempo by the way.
