Hi! 
I’m fiddling a little with Harmonix, and I’m trying to trigger the Step Sequence Player in a “reusable” way. This is my current setup:
(‘Trigger To Midi Note’ node courtesy of GitHub - Amir-BK/MidiDeviceMetasoundWrapper: Real time midi device input into metasounds, and a few other QOL improvements · GitHub )
The idea is that the player should be able to trigger playback of the song, or of the extra note, at any moment, no matter how many times, and it should be sampled by the same “instrument”. Currently this works for note on/off events just fine, but not for the PlaySong trigger. I’ve tried every combination of transport signals I can imagine, but no dice— it seems like, once the sequence has been played, it’s “spent” until I restart the audio component that this MetaSound source is part of.
If I didn’t need the extra note on/off events, I could just plug ‘On Play (UE Source)’ to ‘Play’ directly and tell the Blueprint to play the audio component again (what I mean above by “restart”), but since there’s this case of a potential extra note being played at the same time, I don’t want there to be a cut.
My intuition tells me this should be easy, but I have no idea how to achieve it, and I would be so grateful if anyone could steer me in the right direction— thanks in advance!
