Hi folks

I need some advice, recommendations/ suggestions here. I direct the worship band at my church. I play a Roland Clavinova and do backup Tenor vocals and as far as musicians are concerned, I play along with a bass player, drummer, and an acoustic guitarist. Additionally, There are 5 singers upfron, making it a 9 member worship team. Most times, I use a basic acoustic piano and strings tone or maybe a Rhodes and pads combination. My drummer is okay but not too hot, time-wise. I would rate him as a very basic drummer. I want to do 2 things. I am thinking of using "live" sequences so as to make the music sound richer, fuller with additional horns, strings bells and whistles to play along with us in real time and be able to change patterns in each song on the fly as in INTRO, 1ST VERSE, CHORUS, 2nd verse, chorus, bridge, outro etc etc.

Then too, I want to be able to send the drummer some kind of sync....most probably a light percussion feed, either via head phones or into his drum monitor so that we all stay in sync and tughtly in thaaa pocket. Now, I have some stuff at my home studio such as

(1) a MAC BOOK (just got it yesterday from sweetwater.com) brand new. 2-13 Ghz dual core, 160 hard drive, 2 gigs of ram
(2) a lexicon omega USB interface,
(3) an HP laptop (from Walmart) 17 inch > dual core celeron 2.3 Ghz, 4 giggs of ram, 250 gigs of hard drive space
(4) Have access to an Mpc 1000. Dude next door owns (doesn't know how to use it) it but wants me to use it freely.

Software wise: band in a box 2008.5, (with Real tracks), power tracks pro audio 12, Sonar 4 studio edition, cubase sx3.

I do demos sequencing and small projects and stuff at home for clients.

Any suggestions in using what I have above for the "live" sequences being used on the fly as I need to?

thanks
