Dave Smith Instruments SYNTHESIZERS

hi...

on the desktop evo, you can turn a knob one click and see a parameter's 
value without editing the parameter.

does the MEK respond similarly? if not, how do you view a parameter's 
value without changing it? the manual does not mention this. please 
tell me there's a way to do this, as i really want the MEK but would by 
happy buying the desktop again.

also, does the desktop have an arpeggiator like the MEK? the desktop's 
web pages and manual do not mention an arp.

thanks...
