One thing you could try, assuming you use zyn under jack and it gets kicked  
by it, is to increase the client timeout time with some jackd commandline 
option. This way, even if you get audio dropouts, there's a greater chance of 
zynaddsubfx actually "recovering" because it doesn't kicked by jack so 
quickly.
