I layer A LOT. From LOTS of different sources within the same beat! Now, as my source collection grows bigger, I find myself Wastin plenty time on revisitin samples I already used, sometimes abandonin beats cause I cant find that one sound to complete a piece... Miracle cure was right there all along tho - Ive recently started dedicatin whole sessions to choppin up 100s of records, savin Them to instrumentthemed sketches for me to pull up ina separate window when I need JUST THAT PIANO lol! Works wonders...
