Rendering a VST midi track to WAV to save CPU

[camcam]

Hello everyone,

I'm a new user of LMMS and I struggle with something in my workflow.

I use a lot of VSTs to produce my music and my CPU is frequently overloaded when I have 2 or 3 tracks with a VST.
I wonder if it's possible to render a VST's midi track into a WAV file to avoid rerendering live every time I work on another track.
I have some friends that us FL Studio and can do that, but I didn't found how to do it in LMMS

The only way I found is using the "export tracks" feature, but it exports every tracks at once (and not only one).

And I'm not sure on how to integrate the file in an "audio track" after that. I only see how to do with audiofile processor, but it create an instrument (with pitching depending on the note), that can do the trick but doesn't seems to be designed to do that.

Thanks a lot for your help,
Camille

No not in LMMS. LMMS does (no longer) have a freeze-feature.
What you need to do is to use a recording-program, most uses Audacity, but any will do.
In your recorder-program , just set the default savefolder to User/LMMS/Samples/ <someNameLikeStems>
That will be your new folder under Samples where you save stems from LMMS

True, the better option is to use a Sample-track
You can make your self familiar with this type of track in this video:
