A syncable LFO will go KER_THUNK! when it's reset. While some people might 
consider that a feature, not a bug, it doesn't look like something to be 
proud of in a design.

A digital design, meanwhile, will do wacky outrageous things like producing 
a cycle that's truly a multiple of the MIDI clock rate, no kludging 
required, with optional control of *phase* - not just frequency - if you 
want it.

The only thing that's harder about a digital design is that you have to 
write some code. In terms of on-PCB hardware it's hugely cheaper, easier to 
implement, *far* more versatile, and done properly will produce results 
that should be as smooth, if not smoother, than any analogue design.

The fact that it's cheaper means you can include more of them. You should 
be able to produce a quad design with a bank of customised modulation 
waveshapes for the price of a good VCLFO.
