Noise & Crackle when playing sounds

[Barely]

Hi there,
I couldn't hear anything in the uploaded file, might be my computer.
But yes, this problem is very widespread, and there are people who could fix that, and there were people who couldn't (like me).
The best thing to try is connecting the virus to an usb port, with and without an USB hub, and changing the buffer in Logic (Somewhere in the audio preferences). Don't plug the virus into a hub when there's another device on that hub. Try different USB cables. Try updating to the newest official software release.
If all else fails, use DIN midi, Analog audio and forget the total integration. You still have a gorgeous sounding synth, then
