Hi, You should not perform in Cubase since the renaissance Plugin hasn't good VST Instrument capabilities and doesn't really work as a Midi Controller in CUBASE or any other DAW.
It let you 2 solutions :
- Track in the MPC Software with program and VSTi then export stems in waves files when finished sequencing for mixing and arranging.
or :
- Track in the MPC Software with program and VSTi, save it, Then re-open your project in Cubase in the MPC plugin, Route your MPC track to the cubase mixer for mixing with your DAW. You can also put audio, midi tracks and Vsti tracks over your MPC project.
That's All... I was a bit disappointed to at the beginning, but it's just a different way to work and to think your projects.
In fact, you will see that the MPC sequencer is great and quicker to use than Cubase for recording Midi and using it with VSTi since 1.31, is Stable.
The weak point of the MPC sequencer is the mixer, the routing and the Automation system. This is where Cubase is very Great. It could had been a good combo, this is why I was one of these enthusiast early owner, but unfortunately the plugin mode is not what I expected to...
I'm sure, some update will change these MPC software weakness. Or the MPC plugin control from the DAW ( Better syncing, Full assignable Midi control and multiple program control ) We got to wait for this...
