Electron was the first serious synth I bought, so it's what I learned programming analog synthesis on. (Hardware? What's that?) For this purpose it's an excellent beast. Clearly laid out controls, and the manual explains the not-immeidately-obvious aspects very well. (Ok, I wish it explained more clearly what the difference between the transpose and detune controls are when oscillators are sync'ed.)
There are some things that I can't judge: Muon is very proud of their alias-free oscillators. I guess so. There are other synths on the market that don't remark on this that sound fine to me too.
Having played with other soft synths I see as the main limitation of Electron that the oscillators have fixed waveforms. The sawtooth and square wave sound "sweet", and it is hard to get Electron to produce the aggressive tones you get from a triangle wave.
That said, there are lots of routing / modulation possibilities, and the oscilators and filters sound good at what they do. I have no problem getting useful sounds out of this synth.
I have a few other niggles with the user interface, but nothing major. Actually, there is strange bug in the slider for the cross-fade between the filters. Once you know that, you simple grab it at the corner instead of the middle of the slider.
The presets are not great, but there are several good bank for download right here on kvr.
