I want to use these controllers on my computer, no need to integrate, just want to open each controllers separately but link to my Logic Pro. There seem to a problem as all my instruments in logic pro is gone but i can get them on my S61 at times and at times goes blank or at time everything hangs. Why is that? How do i solve this problem. Just want them separately like and other stand alone controller. After buying and downloading and installing maschine, this happened. I am using Maschine's Interface as my main audio out interface for both. FYI. (But the same problem happened when I had an external usb audio interface. Can someone tell me where I am going wrong? Thank you.
