Hi there,
I want to ask for some advice or help! When I do a tempo change in the tempo track, wether it’s a jump or a ramp, if it is over audio, it makes a horrible crackle. Obviously this is more noticeable over a ramp as the crackles continuously across that tempo change. Any suggestions? Midi instruments are fine, it is over the audio that it happens. I have tried putting the audio in musical mode but it doesn’t change 
Thanks,
Jen
I have solved it! For some reason, it didn’t like the tempo change alng side the chorus plug in on the sync setting I presume, the chorus struggled to sync with the change and so it caused a crackle!
