I just bought the xp-80. I'm actively gigging and don't have much free time immediately, so I was wondering if I could program into memory somehow approx. 10 or so patches--maybe using the buttons on the front. I notice that they keep the last ones in memory unnil the power is switched off. That would be great if I could put patches of my choice there but have them stay when I reboot each time. Is this somehow possible??
