Hi Mota,
Congrats on the XP-80. I have one too and really like it. What you're asking is the very fisrt thing I did with mine.
You need to setup up a User Performance. I overwote the factory User 01 performance. I called it simply Bobs01. I don't have my board or a manual in front of me, but basically you go into Performance mode. Bring up User 01, Go into each of the 16 parts available and assign a patch to each part. Then use the Utility and Write functions to save it.
Then when you're ready to play you turn it on, go into Performance Mode. Bring up User Perf 01. Then (unless I'm missing a step). All you have to do is hit the part button you want to hear. If you set that User Perf to layered mode as opposed to single mode, then before playing hit the Local/TX/RX button and set it to Local I think, then you can not only change patches on the fly quickly and easily, but you can layer in and out any of the 16 patches. Becareful though, poly is limited.
You got a great board and it will surely do what you need for up to 16 parts.
Peace
Bob
