By “older module” you mean 32 bit plugins using Renoise bit bridge? Could be that 10.14 prevents any 32 bit execution at all, so the plugin bridge won’t work.
Do 32 bit plugins still work in other DAWs?
Do ist work if you only load 64 bit plugins?
What happens if you disable sandboxing in the settings (and then restart renoise)?
32bit plugins, when loaded into 64bit renoise, look like this:
When enabling “run all sandboxed”, some 32bit plugins load, but for instance TAL-Dub I & II do not show anything, even sandboxed.
however, i cannot be running plugins sandboxed, as i need to have keyboard input into pattern editor at all times.
this is what ValhallaDSP Freq said, before Renoise 2.8 crashed.
not sure which log to look at?
okay, plugin log says this:
