Rhodes Chroma Polaris

Hello--

I've looked for the answer to my question on previous posts, but I couldn't find it.  If this is a redundant question, please just redirect me to the correct message.

My question:

I have 12 sounds stored on my Polaris, (A1 - A 12).  How do I save these sounds on my computer?  I have sysex librarian, a program on my MAC that can record sysex data.  How do I get the Polaris to transfer its sound data?  I have read the manual many times and tried many things and nothing seems to quite work.  I know it can easily be done.

Second, 

once I have saved the sounds on my computer, how do I restore the sounds if they are deleted?  How do you set up the Polaris so that it loads sounds?  I know this can easily be done also, but cannot figure it out even with the manual's help.  

Thank you so much!!!
