Synth sound ans Drum sound deleted

So i have’nt use my op-1 for a while,and this week i open it with the plan to make something out. But when i did,all the work i’ve done was still There,but not the green section when you get to chose your sound…all the name are on Blue are There,like strings Sampler Ect…i don’t really have a clue of what im suppose to do with that. A general reboot maybe ? But even that i dont know how to get there !

Big thanks,and sorry if my english is bad i did my best :bowing_man:‍♂

its a different button combo
they changed it awhile ago
if u hit shift T1 it just allows u to change the engines while keeping all the params the same
shift +1-8 hot keys allows u to change presets
