It goes further than that.
For instance...say you have a medley of tunes you want to do, you can program 8 registrations under one song name, and another 8 under another songs name and switch back and forth at will while playing.

Each style also has OTS which gives you the ability to use 4 more voice set up beyond the initial 8 in one registration.

And on top of that, with layered voices in the right hand, you can use the two together or select one of your choice for the lead.

The Tyros, 2000 and 2100 are VERY versatile in this regard.
