Jepp, korrekt!

The largest external memory size for AVRs is 64k right?

if so, then this is a big limitation, hmm lets think about it:
  128 patterns = 128 * 16 steps * 16 step = 32kb
  3 songs = 3 * 512 rows * 16 channels = 24kb
  8 kb for other stuff and furure use and.

I guess you can squeeze in a few songs, if you don't store unused patterns, rows etc. but as i said I would like to keep it simple, ie 
fixed size data. Guess I can forget contious controllers, maby I can squeeze in the controllers in each step, and interpolate, inbetween or something.

I am anxious to get started, but I will look through both PICs and AVRs before I make a decsition.
