Why a Tyros guitar and choir, there are plenty of wav samples on the web that are far in advance of anything that a hardware arranger can muster.
I suspect what you are really after is the Super Articulation effect (Yamahas, posh name for layer switching which has been available in the pro market for over 10 years) which is a completely different kettle of fish, and requires knowledge and time to create, (You canít just record a sample and expect it to work like it does in a Tyros) in addition there are many more effects and controls that are built into the sound itself and so it is not just a sample, therefore you would need to add these as well.
If you have the knowledge, patience and the appropriate software/hardware it can be done, but is normally beyond what most arranger players are prepared to take on.
If you do want to try it, just type ďguitar sample creationĒ into Google and you will find various software and tutorials to help you out.
Hope this helps
