Summary0007884: When playback is reset to beginning of song, settings in Helm synth reset.
DescriptionI'm going to be honest, I don't know if this is an Ardour problem or a Helm problem, but on a couple of MIDI tracks (where I am using Helm as the synth), if I reset playback in Ardour to the very beginning of the song (by simply clicking on the timeline or pressing the button on the above panel) it resets the settings in the Helm synth to a previous configuration. While this may be a Helm problem, I think it is probably an Ardour bug because I checked the log and saw the following:

[INFO]: Loading bindings from /etc/ardour5/ardour.keys
Loading menus from /etc/ardour5/ardour.menus
[INFO]: Loading 88 MIDI patches from /usr/share/ardour5/patchfiles
[INFO]: Loading history from /home/<myname>/<songname>/<songname>.history

[ERROR]: could not reconstitute StatefulDiffCommand from XMLNode. object type = ARDOUR::MidiPlaylist id = 596
[WARNING]: MidiDiskstream 327: skipped 1 events, possible underflow
Steps To Reproduce1. Open Ardour on Linux Ubuntu 18.04 LTS
2. Add Midi track with Helm as synth
3. Play track
4. Change settings in Helm
5. Reset playback marker
Additional InformationI've never muddled around in your source code, but I know C++, so I'd be willing to help track this bug down and fix it.
