And Korgs sound mighty fine too with their 48KHz! Mind you I'm not entirely sure that every rom sample is 48KHz on the mid rangers like Triton or M3. But I do know that my 44.1KHz sampled drums collection sound better on the Korg than some other 44.1KHz workstations. Definitely more top end 'air', whatever that means

But after recording it at 44.1KHz, can I still claim it sounds better? Dunno, its different. And in the end its all synthetic, there is no 'right'.
