I just got a simpletech sti-cf/512 from pcconnection and it also works. I copied my song directory from the 128mb card to my Windows98 desktop using an $11 pqi usb cf card reader/writer and then onto the new type I 512mb card. I had to upgrade the mr-8 to version 1.03 or the new card gave me error number 10. I upgraded by unzipping the file from my win98 pc to the 128mb card and upgrading from that card. To test the new card I bounced tracks 1-6 onto 7 and 8 and listened to all 8 tracks different ways. The card was $129 - $50 rebate or $79. The only thing I don't like about the mr-8 is some static when I pan tracks 1-4 very fast. It doesn't seem to show up when bouncing, just headphones or mains. Anyone else have that too?
