Not sure about your Defiler question, but here are the UI's being maintained:
- Probably the most used UI, has a billion options and you need a manual to use it
, it's great.
- Still being maintained by various people.
3)DrumsUI - Drumstix42 has left, but I am keeping it up for a friend and sharing it.
- People say this is still up and running. So you could use this or the manual
Then you need my updated files from post 1 of this thread.
Hope this helps.
