The topic of brushes come up from time to time and yes, so far TTS-1 wins the challenge. All the others, including the Jazz kit brushes in AD2 just don't cut through in a mix. Don't waste your money on the AD kit. They don't even sound like brushes, more like using one of those Hot Rod bamboo things.
I also recorded my own samples and use Session Drummer and still..
the TTS-1 cuts through and sounds like a brush.
The other funny thing is I also find the default TTS-1 kick cuts through and sits nicely in a mix.
I soloed the AD2 kicks and no matter what, there is a bit of reverb on all of them?? what's with that, sampling a kick with reverb? AD2 would be perfect if you could drop other samples into it.
