Hey bea and welcome to the forum. I've been here about 6 mnths and used to record on a PS-02 myself. Really miss the little guy since I upgraded to an MRS-8 a few months ago. As far as compatibility w/Linux...I can't help you there. Try http://www.zoom.co.jp/english/products/ps02/
and contacting Tech support. My unit was only able to utilize a 64mb SM Card so I had 3 of them. One was a working card that I never used and was only for system restore/backup only. One was another exact copy of the working card and the third had these new guitr effects loaded which I really
. Also I had the original factory SM card that came w/the unit to format all the various working cards.
If you search around the Tricks and Tips thread at the top there is a bunch of info/sites that are helpful. One is the Pattern Editor which is essential if you want to fabricate those odd time signatures. I never used it directly w/the 02 but did check out the demo ver for a bit on my PC. It seemed pretty easy to use but I never purchased. I do know that the 02 had a 3/4 Jazz Waltz preset that I used a couple times.
Here's a recording I did on the PS-02 right before unloading it for the MRS-8. Hope to see you on the New Recordings page.
