I don't know how to do, but someone made it in this project https://lmms.io/lsp/?action=show&file=6234, so it's possible, if someone other can explain, i will also be grateful (at now i use only sidechain with bigkixdippa, but i wanna learn also this). I saw he used a peak controller
Ok so you made me dl the project :p Where are there Ghosts?
It is not possible in lmms. We simply do not have that feature
I have speculated in doing it in various ways, but none is really good.
Only 'way' is to copy the notes you want as ghosts into the new song-editor block, then
* Mark all
* Set volume to 0%
Thats 'it'
BUT!
No matter the percentage of velocity, LMMS uses exactly the same amount of CPU. Eg the 'ghosts' will double the CPU-usage for that particular block!
They are indeed not ghosted-notes, they are low-velosity notes!
They do 'act' as ghosts, though..
