Strange no-sound behaviour experienced

[Lioness]

Hi there,

this is my first post here - I am still relatively new to the use of Usine, and I may be looked after if I think something is a bug here and there, which is perhaps just a misunderstanding by me with the complex software.

My first question: I have a grid element in grid mode that contains a rack with two patches: in the first patch a midi file is loaded into the piano roll and that controls the subsequent VST synth patch. Works fine and I get the sound and melody I want.
But now the strange behavior that I don't understand: When I leave grid mode (and it happens, regardless of whether I still have the rack as a grid element at that time or have removed it from the grid), then the Audio signal no longer leaves Usine. And this although the output meter shows that sound is being generated and the tracing of the wires in the output device also shows the audio signal flow is active. However, no sound arrives at the physical output device any longer. I have to restart Usine to get sound output again.

Where is the mistake I'm making, or is it a bug? I am using the current version of Hollyhock Pro (5.1.211124). This behaviour happens regardless the VST plugin I have used in the described situation.

Nothing strange reported at the support. Can you join an example as attached file ?

Maybe a stupid question, but: what kind of file/content would be helpful here for you? Saved workspace?

a simplified workspace to be able to reproduce the problem.
also the LogFile.Log inside the packet of Usine.
