The problems with most drummers are these.....
1) "How are you?" - Your just starting out with a great new album project that requires really good drumming - plot complication: The one or two great drummers you know are in two or three different bands, and don't share your enthusiasm. Great atracts great, so, because your not in an established band, you have to hire the "just OK" drummer down the street.
2) Are drummers musicians? - Most drummers are good at playing their instrument, but they arn't neccesarly skilled as musicians or song writers. The great thing about drummers like Lars Urich, Joey Jordison, and Neil Pert is, they have a creative input into the crafting of the song. You can "hum a few bars', and they already have the drum parts fot it.
3) Costs - as an above poster said, to get a pro drummer, well tuned drums, the right mics, hours of studio time, is beyoud the reach of most songwriters.
4) Pride - a lot of drummers are insulted that you want to incorperate programed drums with their playing, but it's like a gutar player saying he can tune his guitar without a tuner. If the tecnology is out there to tighten up the drums - USE IT
Here is the Mondo formula for the drum tracks to your song
A) Write your song using a simple DAW with guitar, bass, maybe vocals, and simple drum grooves using midi (change up the grooves for verse, chorus, bridge, whatever). Make a click track for the song and mix it down to listenable stereo audio tracks and burn to CD. This is (what's called in the movie industry) your storyboard
B) Give the CD to the drummer in your band, or hired gun (preferably a jazz taught drummer), and let him drive around town listening to it for a couple of days.
C) Have that drummer come in and lay down the drum parts on a midi kit or triggered skins kit. Record his playing with as many takes as neccesary. You might have to pay him a couple of bucks.
D) Now write you drum part using his playing (edit and quatize some parts, leave some alone), use your midi keyboard to add what is missing, and use Slam Tracks ($10) for other groove and fill ideas.
E) Huminize - there are a few posts in this forum on how to make your midi drums sound like they are being played by a real drummer (using velocites and not over quantizing)
E) Now import your samlped drums (superior, BFD, Slate), and get your
drum track as "radio ready" as possible
F) Now conform your guitar, bass, synth, vocal parts to this new drum track
G) (Optional) have your drummer play over the perfected programed drum tracks with a couple of good overheads (or whatever micing you prefere) and mix real with sampled to taste
H) Repeat procedere for the other 7 songs on your CD, mix and master (yourself or at a pro shop) for final product.
I) Tour, sell your CD, sell your T-Shirts, get layed by groupies, get promised you have a 30 minute set and now told you have 15 minutes, make videos, etc..
J) Get famous, get picked up by a record company, and do the next CD and drum tracks on THEIR budget
Good luck,
