Yamaha DTXpress/DTXplorer/DTXtreme

Hi all,

First post so be gentle with me!
This may be a naive question. Was thinking of buying a minidisc or 
Mp3 player. Can recordings made on the dtxpress be downloaded to 
minidisc or Mp3 player? - if yes, what do you advise is the best 
option?

I would also like to make crude recordings of band rehearsals using 
live drums with minidisc just for analysis purposes. I know some 
minidisc players have a mic input, how about Mp3 players? - has 
anyone tried this? is this possible?

Thanks in advance for your help.

GT.
