Yeah, this argument comes up between a classically trained singer friend who thinks loop based composing is the worst thing to happen to music in 500 years, and myself, who can clearly see the artistry in finding and repurposing all that stuff, making it mesh AND make you wanna shake various body parts!
It IS an art form, and very musical. But the debate rages on as to whether that makes you a musician, dj or producer. Some producers have farm teams making beats that they take full credit for, and it's treated as work for hire. Is that really any different?
And Sauli is on to something too. Most of the stuff I hear has pretty complete processing on everything, so using one shots saves time making heavily "produced" sounds from scratch. And I often use the handclaps, shaker, tambourine or cheesy organ drum box loops to do percussion sweetening, and it sounds great, and right
Speaking of loops and construction kits, all the Sampletank Retanks are on sale at eSoundz for $10! Some are full kits, others are drum/percussion loops only, but they'll all run in Sampletank free, so not much to gamble really!
Try it, you'll like it!
