what could be the cause of a few hisses and pops in your recording ? i am just using vst instruments. could it be that volume is too high ? other then that the sound quality is amazing.
Its easy to see if you have to much volume, You should not have anything in the red-area unless it is effects, or something soloed
The correct setup in lmms is to allocate one FX-mixer-channel to each track-instrument, now you can precisely monitor the output over time, either in the mixers visual dB-meter, or you can add more sophisticated monitors to the channel-FX, like SPAN
I once made a series of vids that shows how to connect and monitor in Mixer:
Now you have a good foundation for finding and elimination distortions from loudness.
Distortions can also be created from insufficient setup of your Envelopes, ither in LMMS https://docs.lmms.io/user-manual/3-navi ... .2-env-lfo
or in the VST, where the ENV is defined.
Make sure thats not the case.
