MU4 - problems with third party plugins
OK - first - I realise that there's a GitHub way to report problems, but I don't know how to do that, so for me it's quicker to post here. Maybe later I'll find a way to get GitHub to work for me.
I have been testing MuseScore 4 recently, and found that I can install plugins for libraries, and also some effects. Besides MuseFX I can also install other effects such as SurgeFX and the Klanghelm DC1A3 compressor. I also have had several third party synthesisers working, such as Surge, Dexed etc.
I also tried the Waves stereo headphone surround sound mix plugin, but apart from the Head Tracker - which worked - it didn't otherwise function. When I tried that in Logic it worked much better - almost as I expected.
The most recent test has been for Melda Production's plugin MCompressor - which I suspect is very good. I have tested that in Logic, but in MuseScore 4 it locks up the interface and the MuseScore program has to be forcibly shut down. In Logic I think that does work slightly better than the Klanghelm compressor - but it doesn't work at all in MuseScore.
You can find the relevant MCompressor plugin here - https://www.meldaproduction.com/
This may not be something you want to deal with right now, but I thought it worth a mention.
