Sev01,

The new OS3.0 for the SD1 will be released within the next couple of weeks. There are some modifications to the arranger component with some new features especially for the PATTERN EDITOR. Unfortunately, I do not use the SD1 with cakewalk - but I can suggest that when using the SD1 with any external unit/software, you may want to use the GM voices rather than the PRESETS (since these may not neccessarily be in GM format).
Hope this helps,
AJ
