My sound presets disappear

I have imported a musescore score in midi format into ardour. I want to use zynadd for the sound but the chosen preset doesn’t register when I stop. I guess the path is no longer good and ardour can’t find the preset?
How to rectify this problem?

Thanks in advance

Nobody ?? I still try to find a solution…

I am sorry I cannot offer any help here, but it has happened to me with ZynAddSubFX as well. (I think it also happened with Yohsimi…) But I don’t think it has happened with any other plugin. The weird thing is that, at least for me, it does not always happen…
