I usually sample sounds thru several hadware effetcs modules. Record that op my pc, add some extra effects on FLoops end/or Wabelab, load those samples in to the Yamaha RS7000 as single shot samples or loops... And then sequence it and play it live. Actually everything what I record is played live. It has some restrictions, but for me it works best this way... This way I can give it a more organic feeling and can get new results quickly just by jamming on the RS7000.

I use extra outputs on the RS700, where i can send channels throuh the same effects modules used first. The RS7000 runs together with a laptop running Cubase for more complex sequencing and controlling other sound modules.

I would say, try different setups and sequencers. There is no such thing as a machine to build a house. It's all tools. :)
