Cheap emulation of the famous synth.

32-bits only, give a idea of what is the real one.

I use it one time on my production.

OK, everybody knows this is a 303-knockoff. Yes, it's a one trick pony. Yes, it has only limited programmability. Yes, the 303 sound has been abused ad nauseum.

This little gem, however, just plain sounds GOOD. I have to say there are very few synths out there that can make as tight a bass sound as this masterpiece by Muon. The fact that Muon gave the synth away just floors me. Put simply, it just sounds fantastic. Forget the squelchy acid sound the 303 is so (in)famous for; instead, use this beauty to make sub basses, punchy smooth basses, even the occasional harsh bass. I love it.

I own Tau Pro, and I still keep Tau in my arsenel. Why? It's just the most well-focused little soft synth I've ever seen. A classic.

I've been using this synth since I first started reading CM magazine abaout 6 months ago (it comes on the cover CD). In fact, it was one of the first VSTi's I used when I first started using Logic. Since then I've become a VSTi junkie (as so many have), and have used just about every one out there. But I probably used this one more often than any others in my songs and most likely still would had I not purchased the Tau Pro.
NO, IT DOSEN'T SOUND JUST LIKE A 303! But I don't ever recall the 303 being given away for free. And with a little bit of properly applied effects it can do a heck of a lot.
That pretty much covers the pros as far as cons the only real one is the lack of presets. Not that big of a deal, especialy since it's so darn easy to use.

Tau + distortion + Stereo delay = monophonic heaven.
Glide is a very useful feature that I use a lot. I recommend the Tau as a substitute for any monphonic string lead, although use a chopper effect with it, or convert to staccato 16th notes...

I also have to review this, after reading a not so favourable review. I disagree, but I respect that person's opinion... Personally, i think that it looks lovely. Now, for the sound, I dont know how a REAL TB-303 normally sounds, but i use this one very frequently because of its very pleasing(to me) sound. Also, i wouldnt describe it as a one-trick pony, because I used it for leads and not only for basses. The included mdrive effect is also very nice... Yeah, it has not presets, but so what, its not like its the most complex synth in the world!

And it never, even once, crashed on me...

Discontinued .


The others (Tau Bassline MKII and Tau Pro) are shareware (the free links are only demos).

Good products besides this... but the lack of information on this actual KVR page (the missing state "No longer available") leads to a confusion.
