This is a known bug. I think it was fixed here for the next release here: Issue #8651, PR #8652. Perhaps some dev can confirm it.

That is excellent news!!! Looking very much forward to that!

Can I use your forum email to put you in touch ? no need to share it publicly

@OmriLahav

I am a professional horn player and I love 0 A.D.! I heard a track with MIDI horn and thought I would volunteer my services. I have two horn performance degrees and practice a good deal. I don't think submitting an "application" (as detailed in the sticky post in this topic) makes sense because I'm not prepared to volunteer 10+ hours per week. Let me know if I should be going somewhere else to volunteer my services! I have large- and small-diaphragm microphones, a good recording space, and I use ardour for editing and mixing. I have mixed many tracks in the past, and am very conversant in digital audio manipulation and digital audio workstation concepts and practices. I'm also a software developer, and very technically inclined. I also play cello and classical guitar...not quite as well as horn, but 0 A.D. music doesn't tend to be technically demanding, so I think I could make excellent-quality submissions on these instruments if it would be helpful.
