The following data is not reflected although OS-XL is compatible.
The data of Q-link is not reflected.
A setup of not Non-Destructive Chop is not reflected.
A setup of mute of a program is not reflected.
Since specifications differ, a setup of a cycle is not reflected.
Other tracks are influenced when the same program is used. (It is the same specification as OS's other than OS-XL)
Since the value of a parameter is not correctly reflected when the program made from OS3 is loaded by OS-XL, it may not sound to the right sound.
Therefore, if you want to use a program created in OS3 with OS-XL, you need to correct the parameter values correctly.
