Pro: + great sounds, fat basses and more + easy handling user interface + MIDI controllable + good value-for-money rate + support
Con: - No ADSR envelope - No pitchbend
Insipired by the legendary TB-303 (but being much much more than 'just' a clone), you can use this VSTi to produce several kinds of those 'typical' 303-like techno/acid/trance bass sounds with filter and distortion treatments. Beyond that, with additional features like 11 waveforms per OSC and onboard FX, it's capable to create rich fat leads as well as other sounds.
You could miss ADSR envelope and pitchbend for bass slides. The original 303 didn't have those features, but I think they should be 'standard' in current highclass VSTi's.
Anyway, this is just a minor restriction. I use this VSTi a lot, it's my prefered bassline synth, and the easy handable interface makes it just fun to play around and modify the sound.
