ok, I'm not a pro, and I've never done hip-hop. With that said, I do do industrial electronic stuff and if I was in your situation, I would: Track the drum machine like real drums, (seperate tracks for kick, snare, toms, hat, overheads...). I would use the preamps. Most of your groove boxes run a line level signal, treat them like you would a synthesizer, and use your outboard pre's as a DI. His gear should be "up to the challenge", (although, I've never been impressed with the asr-10), the 909 has been done to death in dance circles, have him bring some music to listen to as reference. I'm sure he has a reason why he likes that drum machine, try to emulate that. Seems the roland "X0X" boxes are standard for dance, rap kind of stuff. Starting with the "groove" would be a good idea. Lay some solid drum tracks, add some bass and go from there. Keep those compressors handy and work them hard. Be ready to double the vox, a lot more than what you feel is natural. When in doubt over anything, consult the producer, I'm sure if he's doing all the music that he has a pretty good idea where he wants it to go. Lastly, (and you should probably do this first...) spend some time listening to a few hip-hop cd's. I hear a lot of it at the gym and it's fun stuff these days. Have your producer recomend some. I hope this helps/inspires you. Have fun! :w:
