Dave Smith Instruments SYNTHESIZERS

Hello,

My name is Margaret and I own two DS synths. I first purchased a mono keyboard evolver 
and most recently added on a poly evolver rack. I am trying to do several things and have 
not been successful. I had a few questions and i was posting to see if anyone else was 
experienced in these issues and knew how to correct them...

1. I am having trouble with the editor. it seems that i am unable to go between my poly 
and mono keyboard on it. i have to reinstall the program with different registration codes 
to work with each synth and still errors are coming up about being in "demo mode" even 
though i have licenses for both editor modes. anybody else gone through this madness 
and solved it? 

2. Also, when editing the poly rack with the mono keyboard (without editor), is it possible 
to open combos and then edit each voice independently on the rack via the mono 
keyboard? if so, how? :-) 

3. I have saved as a file all the presets and banks from my mono keyboard as a .evi
file. how do now save these into the polyrack (assuming i ever get the editor working :-o ) 

thanks in advance for any help you may be able to provide!
