The above is a link to a lua file (written by me) which can be used with Renoise and a tool called Guru, which then provides a GUI for total software control of the DW8000. I know the demo version of Renoise has very few restrictions so this may be usable even without paying for Renoise (which is cheap and brilliantly versatile).
I'll post a photo so you can see what it looks like.
Renoise is here: renoise
Guru is here: guru
It's all easy to use, but let me know if i can help get anyone started with this.
