Muffled issue with MIDI SF2 and VST in the piano roll

Having trouble with LMMS? Ask about it here.
Hey, thank you for your support, MusikBear! I tried to follow the tutorial but apparently it's an issue that needs filters and external improvements to be solved, isn't it? I think it will make it very difficult to fix because I will need to apply those filters on every instrument and since I am looking for a realistic instrumentation, I may need to add even more effects. I'll wait and see if this bug gets solved next patch, but I appreciate your effort in overcoming this problem.
Hi, I know this is an old thread. But I seems to have the same issue with VST. I tried Spitfire Audio Lab and Keyzone Classic. Both same issue where the VST interface is clear but recording in Song Editor is muffled. I added other available Instrument plugins, They all sounds great in compared to muffled VST.

Seems like everyone else don't experience this?
