Hi sveakul good to see you too bud. Yeah I've updated the new mb_VST. I already had the newer version of bass_VST.dll that is 220.127.116.11 so I skipped that from Steven's post.
Although it's still buggy but solves a lot's of issues, the most prominent of which was not saving the snapshots/banks. I've tested the latest version of this plugin with quite a lot of plugins and it saves the snapshots just fine. All Voxengo plugins had this issue but it's solved now. And all the Toneboosters, Sonible, Fabfilter, Acon plugins are working as they should, no errors. Oh! and Tokyo Dawn Labs plugins are also working fine without any errors.
However, DMG Audio plugins still have that GUI not responding issue that I was seeking the help for. So it's still work in progress. We can only hope that Steven get around one last time to update this plugin and it becomes stable and fully functional.
I did't try Acon chainer but I did tried another VST based wrapper with the mb_VST plugin and it's working the same way the mb_VST works. Fine with the plugins that already work and buggy with the plugins that have errors with mb_VST plugin. I don't think we need a wrappers anymore within Musicbee since the snapshots are being saved now and multiple plugins can be hosted. Moreover wrappers solve nothing that mb_VST throws errors for. I think the wrappers are only needed if a plugin has no support for VST2 or for the bridging of 64bit to 32 bit. More and more companies are now ditching the 32 bit versions. Toneboosters being the latest in the list. Someone also complained about Goodhertz plugins not being detected, cuz they are only 64 bit. It should also be noted that the wrappers will add unnecessary latency to the stream.
Here's a wrapper that you should try out https://ddmf.eu/metaplugin-chainer-vst-au-rtas-aax-wrapper/
I will await for your analysis and please continue posting in the thread, you've been a lot of help.
