Mariana

Mariana sounds unmistakably like a Moog without sounding just like a Taurus or Mini (or anything else I'm aware of that Moog produces or has produced.) Though it retains an unmistakable Moog patina, it is quite its own beast and has turned into one of the first plugins I check out for bass sounds. It is simple enough to turn out quality bass sounds easily, yet has a couple tricks up its sleeve to set it a bit apart and point it in a modern direction. And it has more bottom end than almost anything I've heard. If you're in the market for an extremely solid bass synth capable of subs, understated tones, more aggressive textures, and almost anything in between, you should definitely check this out. There is a trial for download to help you make your own judgment.

One more comment: Mariana works great with MPE: I've using an Erae Touch to great effect with it. Very cool.
