I ran into some reverb or delay artifacts when switching snapshots. ( half way through the 20 second clip below ).
On another forum the advice was that it's ok to use the output block to set overall patch volume, but do not use that on a snapshot basis ( instead, change snapshot levels prior to any time-based effects ). Changing levels per snapshot in the output block has been a standard practice for me, especially if amp channel gain couldn't get it done.
I don't recall if delay or reverb tails were on but at the moment of the artifact I had a fair amount of delay and Glitz reverb running, going from a slightly higher gain passage to a milder passage when snapshots were switched.
It was also suggested that delay feedback/mix and reverb decay should not get adjusted snapshot to snapshot.
