iMS20 app with delay effect

[newonhere]

Hi, everybody

I've just bought my iMS20 App for iPad. I have an iPad Air 2. My problem is that when I play the sounds they all sound with a delay effect. I've just deleted and install again the app but ... the same thing !

If this can help I tell you I have GarageBand, Fairlight, Super Manetron, bs16i, Audiobus, Sunrizer and Pro Keys apps installed too.

Any help, please ?

Thank you very much in advance.
