I've been looking to upgrade the standard 8GB sdhc card that is included in the box with the R-07 with a 32 GB.
The Roland compatibility chart states only that Panasonic cards will not work nor will sdxc cards.
Any ideas if the San Disk Ultra sdhc and/or Extreme sdhc card is compatible?
==================================================
Spent some time over at
http://rolandusa.com/backstage looking for answers on the above.
Although there is no specific information anywhere for the R-07, one post addressed a different unit where Roland recommended class 2, 4 or 6 sdhc cards for compatibility.
Several google searches about sdhc card classes (this is all new to me) say that UH type cards will not work in a non UH compatible machine. This would eliminate the Sandisk Ultra and Extreme cards.
It appears that in the 32GB capacity, Sandisk only goes as high as class 4 micro hdsc cards.
I also specifically mention Sandisk here because the Roland manual lists only Sandisk cards as recommended for the R-07 at this time.
