I’ve re-checked this and the sound works fine in FS and Reaper for me. So I can’t explain that unfortunately, because I don’t get the problem.
When I load a wav from a folder all the wavs
do show up in the display, for me anyway. However the DAW will never remember the chosen wav because it won’t be stored in the wav array prim. As trog said, that has to be baked in from the FS schematic.
My understanding was this would be like a ROMPLER, where
you decide at the design stage what wavs would be included, and the presets would select from those
fixed wavs according to the sound design requirements. Therefore I’m puzzled as to why you would want to load a new “ROM” which would entail making a completely different system. Maybe just remove the LOAD button?
In my view, as long as you baked in a great set of wavs, you would have potentially a great and very versatile synth without having to load any more wavs. But that’s your choice my friend.
