One of my students is composing a song using Kontakt's "Elektrik Guitar" instrument and Guitar Rig. There is one part of her song where a weird glitch keeps happening. I have isolated the problem section in a project file and I am attaching the link to this message.
In this four-measure section, the guitar is just playing whole note power chords. The glitch happens towards the end of the third measure, it makes the audio kind of stutter, as if the guitar suddenly started playing 1/32 notes instead. It only happens in this one spot, and it happens about 50% of the time. It's not an audio interface issue, because other track in the song are unaffected.
In the project I've uploaded, I kept the original midi item, but I also applied FX to mono output so you could hear the glitch, in case it doesn't happen for you. I did several renders, and as expected the glitch happened in some of them but not all. I left in two audio takes, one where the glitch happened and one where it did not.
This project was composed on an iMac, but I transferred the project over to a Windows laptop using a completely different audio interface and the problem still happened.
Can anyone tell me what's going on here?
