I'm trying to get an acoustic bass to work realistically in LMMS, and one difficulty has been connecting the automation volume to each little point I've drawn in the SoundFont. I have to do this to get rid of the attack that makes a horrible sound at the beginning of the bass (since envelopes don't work here).I wanted to know if there's a way to cut just one attack from the beginning of a note and then repeat it more easily, or am I forced to do this at the beginning of each note?This is annoying because I have to keep comparing the MIDI graph with the automation graph to see where each attack starts and then find the corresponding location on the automation graph.Can someone answer me? Thank you in advance.

Unfortunately with Soundfonts you cant set an envelope, and that would be needed for the functionality you are looking for. But why do you want to use a Soundfont for this?
You could either find an acoustic bass VST2 or perhaps build one yourself in ZynAddSubFX, witch is a very good generator. There is also the option to find a different SF-player that has an envelope.

ZynAddSubFX! You've really piqued my interest now, I should learn how to use it. Do you have any initial ideas for me to start exploring ZynAddSubFX? Because I know it pushes LMMS to its technical limits.

ZASFX is not pushing LMMS, it is quite CPU lean, so you can use many ZASFX instances in a project.
I have made a playlist with both beginner tips, and some more advanced. You find them here:

Hey, one thing worth trying is lowering the velocity of your notes directly in the Piano Roll since a lower velocity often softens or completely removes that harsh attack on bass SoundFont samples. Also, if you haven't already, try setting the Attack knob in the SF2 player to 0 and see if it makes any difference, sometimes it does even when it feels like it shouldn't. Another solid option is to open the actual sample in something like Audacity, trim the attack at the waveform level, and then reimport it as a custom SoundFont so you never have to deal with it again. That way you handle it once and forget about it forever instead of chasing it down note by note!
