Renoise has always been promoted quite okayish, but I agree version 3 got less attention. This is probably due to the fact that version 3 polarized the Renoise community quite a lot and there are still conceptual things to even out, which will probably happen in the next release. I could imagine, that taktik and crew want to wait a bit longer until things are as awesome as they initially planned.
There are good/famous musicians using Renoise. There is B-complex, who makes amazing music and got quite famous in the DnB community! There is Perquisite, a dutch producer who, together with Pete Philly (a Dutch, yet English singing Vocalist/MC), made an amazing album that was not only famous in the Netherlands, and even featured Talib Kweli!
Well…Better support for drumkits in the sampler
The demo songs to me show that Renoise wants to be in a niche. This niche is intelligent dance music or whatever this thing is called these days. It is all about songs being complicated, new, unexpected and “intelligently” arranged. It is not the thing I personally would listen to in my car, dance to, or just listen to on my headphones while walking outside.
A wider spectrum of genres would certainly be nice. (Get a demo song from B-complex for instance!). Before I got into Renoise, I myself always ignored it in the past, because I have been under the impression that it targets a very specific niche (as I said, IDM, and maybe chiptune stuff). This impression was so strong, that I never demoed it even. At some point I realized that Perquisite was using it and this alone actually made me realize that, despite how it is perceived (and maybe even designed to be), Renoise is more than a very esoteric “techno machine” (excuse this rather negative expression, but I read it somewhere here on the forums lately, and it somehow got stuck). This, and the fact that I remembered they support Linux natively, made me give it a try.
Your last point Bit_Arts…well, yes, I know what you mean in particular (hence the comment earlier on not marketing R3 that much for now).
What I am trying to say is that Renoise does nothing to appeal to a larger audience. If this is intended or not, I don’t know.
So, to wrap up my long response: Show the world that Renoise can do all kinds of electronic genres, including the more popular ones. Dance, DnB, Dubstep, Hip Hop, Bigbeat…you name it.
