Max dimension for SF2 soundfont files and arpeggiator question

Using Zynthian
1

Hi all
I am very interested in getting a zynthin unity. I have 3 questions:
a) My main interest is to play fluiidsynth wiht sf2 custom soundfonts. is there some limitation related to the memory of zynthian for loading sf2 files?
b) How many synths is it possibile to play at the same time? suppose a Fluidsynth for drums, one for bass, one for lead and the last for pads. (even without layering)
c) is the some engine that acts an arpeggiator driving other synths (with midi connections)

thanks in advance
Alex

Fluidsynth sf2 is no problem. But if they exceed 700MB, you hit a border.
