I have bought a license for Serum 2 a couple of weeks ago after a great time playing with the demo. Great fun building patches in that one!
I had been using Vital for quite some time and still nothing comes close to that kind of easy and quick modulation system, but damn.. serum tops it for me in terms of filter and fx quality. The sound engine is also a touch more ‘pristine’ if that’s the right word. Probably the way the oscillators are oversampled.
Anyway; can definitely recommend. If you like rolling your own patches with an do-it-all-the-only you’ll ever need-monster synth: look no further.
