The 320, 280, and 390 all have their own niche, and all are useful. I 
have all three in my system.

Don't sell the 390 short. With it, you can get 4 LFOs in the space of 
a single 320. Two of those have VC, and all have LEDs (essential in 
an LFO, IMO ). Makes a great companion to the 320 - it's a waste to 
use an entire 320 as a gate generator.

I don't often use the individual outputs of the 380 as separate LFOs, 
but mostly use the summed output. It's the same effect you could get 
by running any 4 LFOs into a mixer. I find it most useful to have the 
lfos running at different speeds between 2 Hz and .25 Hz, just subtly 
giving a pitch waver to VCOs without sounding mechanical.
