Lol you really are completley up your own arse mate with comments like that.
The guy has a laptop & abelton already & obviously he hasnt got 40000 grand to spend on a machinedrum. He likes the idea of having DEDICATED groovebox to play with. I have had both a 909 and RS7000 (unlike you.. ie you prob played with them for 30 mins and took your usuall judgemental stance and dismissed them as rubbish). The RS7000 is brilliant live - really ****ing great, its what it does best. OK The sounds are not up to the standard of the access virus or whatever but they are better than the 909 thats for sure. And of course the fact that you asked me "what the hell made that sound" when i played you a clip of a track I made with the RS7000 totally blows that argument out of the water. It a powerful machine and in the right hands can obviously convince people like you (who have obviously used more hardware than I have even seen ) that they are listening to something NOT made by yamaha.
Anyway for me the RS is another piece of the puzzle. I like mixing the sounds of different pieces of manufacturers hardware together (virus, rs7000 & korg electribe) as well as samples from a pc (pc through the mixer). I hate the idea of every single sound starting its life off in the same DAW that the whole unvirse uses. How discordian of you to advise him to get "abelton & a controller" like 99% of people do. Radical.
And a message to the origional poster.
Think for yourself dude. You'll sound more unique for it.
