(I didnt write the following :])
Did someone write a converter or a confortable pattern editor ?
I'm on the way to do it...
info: v3.0 .sav files are the same structure.
Please contact me if you are interested in -> bill(hat)mylgd(bot)com

it shouldn't be that hard, empty note space = 0, c-3 = 1, then the value is incremented for each added halftone up to b-8

hehe, it's working fine ! :) “C-3” -> #01 / “B-8” -> #48
