You need to adjust the audio buffer numbers and/or size. The simplest way to do this is to use the Customizer (click on File, then on Customize). Click on “Next” a few times until you get to the last page, called “Customize Fluidsynth Sound”. You need to increase the number of samples in the buffer (typically 8 – modify it by increasing it by even numbers of samples i.e. to 10 or 12 etc.) and /or the buffer size (typically 512 – modify it by factors of two i.e. to 1024 or 2048 etc.). These increases will worsen the latency (i.e. increase the delay between playing a note and hearing the sound), so you should not overdo this. Press “Enter” before clicking on “Finish”. And if you are satisfied with the changes, make sure that you save the disposition.
Consult the answer given above, but reduce the buffer numbers and/or size, observing the guidelines in the answer. The creation of static and crackles indicates that you have gone too far. If you can't get a setting which satisfies you, the solution is to install the Fluidsynth backends. This process is described in the first topic of the ADDING page of this website.

It certainly does. This is the main way I play jOrgan VPO’s on my home console organ, using two RPi 3B+’s. To begin with, one is dealing with audio and control of half the stops, and the other is dealing with the control of the rest of the stops. The main limitation is the RAM of only 1 GB, but I am getting superb results with a soundfont of about 200 MB. The release of RPi 4 with a RAM of up to 4 GB changes the whole landscape for jOrgan use. I have written a comprehensive tutorial which can be downloaded at this link:
