Configuring Mainstage 3 for live vocal performance with external piano and internal piano recording

Hi,

I need need advice on how to setup Mainstage 3 for live performance of vocals and Piano... basically this is the setup I need:

- Mainstage to add compressor and some effects on my voice. THe voice will be routed to one of my audio interface (Scarlett 6i6) outputs and to the amplifier.

- I don't want to use Mainstage piano sound. I use a high end Clavinova that has a very nice sound, so I won't use the built in Piano for the performan... but...:

- I would like to use the MIDI of my piano as an input into the 6i6 into one of the Mainstage pianos so that MainStage records my voice + effects with one of the internal piano instruments. (But this instrument won't be used for audio but just for the recording.)

- Basically this means I would like my voice to be routed 1) to one of the audio interfaces outputs (that goes to the amplifier so my voice is heard) 2) also my voice and the internal piano sound played from the MIDI into another output of the audio interface that will not be heard but that will be used for the option of Mainstage recording;

This way I am using my Clavinova sound for the live performance but Mainstage internal piano for the piano sound that is recorded. Does this make any sense? Thanks for any advice (and directions on how to configure Mainstage)

Cheers,

Ignacio
