Dave Smith Instruments SYNTHESIZERS

My question is about how well the Evolver synchronizes to incoming 
midi clock.  Is there anyone out there that uses this device synced to 
drum machines and depends on ultra-tight timing?  Does the Evolver 
ever drift, for example when different sound parameters are selected, 
while in sync.  

Does the Evolver ever hicup while the it's sequencer is running?

Is it possible to edit sequences while in external sync mode?  If so, 
does the Evolver ever drift out of sync while doing this?

How many sequences can be chained together?  The manual seems to only 
mention 4 possible sequences, what is that the maximum number of 
sequences that can be used at one time?  

Do the sequences get saved along with the sound parameters in each 
program?

Is there actually a swing function, the manual mentions it, does it 
sound good?

Lastly, are there any limitations in this machine that are hampering 
any of you guys out there?

Thanks a lot, this machine sounds interesting!
