Summary0006790: Hanging notes, if (dense) automation for the LV2 synth plugin is on "play"
DescriptionA MIDI track with an LV2 synth plugin. Automation for one of its parameters. Everything fine when writing automation via bound fader. Once automation is switched to "play", hanging notes occur. Legato notes and high density of automation nodes may be a factor.
Steps To ReproduceAttached session. Compare playback with automation on "manual" vs on "play". Duplicated tracks to compare 2 synth plugins (they show the same result here).
TagsNo tags attached.

Ardour 4.7-218-gbb79b63 solves part of the issue (no split cycles for LV2 midi synths when playing automation).

The initial solution/workaround in 4.7-15-gf6fe87d was not working as intended.
