Not sure where to put this because it’s not a support thing or definitely a bug so I thought I’d post it here and if it needs moving that can happen.
I’ve hopefully put the image just above and the guitar is strange in the way it is mostly white rather than with white lines and blobs, I presume this is just normal rather than a bug and possibly connected to how loud the guitar is. For comparison it is a pretty similar volume to the harp just above after the massive mix change. The guitar is an overdriven guitar sound.
Has anyone seen anything like this before or can explain why it looks like that?
Waveforms become “squashed” like that when the sound is heavily compressed, distorted, or clipping. If it’s clipping you’d probably notice pretty harsh distortion. As long as it doesn’t sound bad to you there’s nothing inherently wrong with how it looks.
I see you have the volume slider on your guitar track all the way down. Perhaps it’d be a good idea to lower the output of your instrument (DSK SoundFont player?) instead. That way you can use the track volume slider’s full range and won’t be limited to the bottom ~10% when you want to make small changes in the mix.
Yeah, it’s sounding fine, doing what it’s supposed to do. Thanks for advise it is useful, interestingly after the change you suggested it has gone to a more normal looking diagram, so I presume volume has something to do with it as well as distortion.
