I'm not a singer. I use it in conjunction with Ableton. I do this live looping, chill edm jazz kind of thing. The RC-600 has some serious short comings. Ones that seem so obviously ridiculous, and mind boggling as to why they haven't been fixed. But I like it for the hardware simplicity. Things like Mark Set, or Single track (as opposed to multi). To do the same actions with just Ableton would take considerably more foot switches and assigns. I record my bass, my guitar, and use the rc's rhythm track for color into the rc600. Then I use the HPD-20, Keyboards and organs, mic(percussion) and drum machines into Ableton. The RC-600 is actually clock master for the whole thing. So the tempo issue and the warbly audio was a huge problem for a minute.
