Cubase doesnt do that trick in no way as fl studio , for that fl studio is a winner on how easy it does that trick, you can do edm trap glides with bases but thats not easy too . I own alsof fl studio and your solution is simple … load fl studio as a plugin en do those 808 slides in fl studio while its synced to cubase … load fl studio as vst plugin … easier it wont get … dont limit yourself … ps ive tried it numerous ways in cubase and in no case the same results as fl studio …
