Summary0009232: Static coming from multi-out synths
DescriptionOn a couple of projects which have multi output instruments, I've noticed a persistent distortion when more than two channels are in use since 7.2.262. Issue does not occur on versions below.
TagsNo tags attached.

Could you elaborate? Perhaps attach a screenshot of Ardour's mixer window, that may be helpful.

Which synth plugins are you testing with? How is the signal routed (do you bypass the panner of the track..)

It's a little hard to explain, but for instance I have Kontakt running 8 channels out in a midi bus which bypasses the panner. One of the channels is in stereo and is the one with the persistent static. On another project, I'm using a drum synth that outputs 8 channels. The kick is distorted in a similar fashion, however the other drums are normal. The panner is also bypassed with the drum synth.

This issue only seems to be isolated with a few previously saved project files. When creating a new project, adding the same synths does not provide the distortion.

I found another project which shows the static clearly in the in-line scope. This is pretty consistent with most of my projects now.

Another project with scope set to log scale. Notice the noise peaks. Still apparent in nightly 7.2.273

It seemed the issue was occurring with Metaplugin's oversampling modes from a recent update. Closing this.
