During my few years of hobbistic music producing I lost tones of hours for put convinience order in my audio samples library. There were obivious attempts for sorting them in directories with instrument names (../tr909 or /piano or /basses) but when it comes to selecting proper sound it was totally disaster. The reason I think has a two roots. The first was the lack of idea how sample will sound in context of project. When I want to use gritty snare I have to go throught all samples in ../snare directory, there were a thousands of samples with snare. So how within a second localize the proper one or at least limit search base?
