I've found that when I sync loops the first loop works fine....but loops sync'ed with it have a 'click' or 'pop' at the loop point
Also when I make connections to sooperlooper loops via qjackctl connections, I'll get a nasty 'crack', 'pop', 'click' or the like, everytime I make a connection....no xruns just noise at connection??
Ok I've further discovered...that I'll get added noise in my loops when i press the record button to stop recording a loop so that then becomes the beginning of the loop. So if i were to record a loop with just one continuous note for 5 seconds, the created loop would have a click from the action of stopping the loop recording So every five seconds I'd get a click in the loop...instead of the sound of one note repeating every five seconds...not good
Check the value of your xfade parameter. Normally loops ends are always crossfaded with the beginning on loop completion to avoid exactly that. If that isn't it, attach a saved SL session (no audio) here... thanks.
After more playing around...it's just a problem with continuous sounds...if I record a loop with a sequence of notes as would be the common use...it works good.
