I purchased after reading rave reviews and auditioning the demos on Waldorf's website. I have been into synths for many years now, as a professional user.
The user interface is not as 'knob endowed' as the other synths I own (Novation KS4, Alesis ION, Roland to name but a few), but it really is the most simple and user friendly interface I have come across, and is certainly the next best thing to a full knobby interface. After a quick browse at the manual, I was soon producing my favourite patches, I just love the fact that even simple detuned 'sawtooth' waves produce warm pads, and that's even before you start using the wavetables and samples!
All in all this synth is very inspiring, and offers something that most synths cannot achieve, keeping even the most seasoned synth programmer happy. Recommended!
