Sorry, been away for a long while,
Thanks for the reply. It works on Halion Sonic SE, but not on Halion Sonic full version, tried it blank project
Have been using instances of retrologue 2, after a while the signal will audibly swing 80% to the left channel.
Checked the panner on the channel itself, central (no automation set, even clicked on bypass for good measure).
Physical connections to mixer and such are all good.
The only way to fix this anomaly on an instance of a Retrologue instrument channel is to assign a MIDI track to it and then give it a cc10 (pan) value of 64.
The pan issue occurs after 3 minutes of Retrologue instrument channel being added.
Addendum: I just wanted to mention that I disconnected any MIDI devices to ensure no CC messages were being sent to the DAW that might affect Retrologue panning.
