That album looks like it's gonna be dope. Lots of good producers on there. I'm surprised they didn't kick Fat Joe out of DITC after all the super wack shit he put out.
Ya, arranger is good. I'd say about 99% of people in reggae have once called themselves arrangers, even if they coulnd't read a musical note to save their lives.
I like Automator, but did not like Deltron 3030. I bought it when it first came out years ago, but I traded it in for a reggae album. It was OK, but not my steez. I feel Co-Flow accomplished it a bit better.
I know what it's like to want music equipment, so I know the feeling! There will be others that will pop up no doubt, just hang in there. the MPC will do you good, trust me!
