The first row's squares denote the following instrument aspect denominations; > Percussive; Samples sourced from drum machines populate the majority of this library. There is no provision against featuring custom or externally sourced sounds which logically belong here. Within this category, key kit pieces and beyond can be explored. > Synthesized; Samples sourced from synthesizers populate this library. Melodic samples are intended to adhere to a standard note, making porting/swapping an easier endeavor. 'C' is the current target. Within this category, all manner of synthesized instrument types are found; Synthetic basses, pianos, brass, orchestral, etc. > Recorded; Samples sourced from microphone/preamp recordings are found here. Real 'DI' performances are stored intuitively in the 'Performances' section. Bits and pieces of DI guitars, bass, etc. are found in 'Cuts'. > Stolen (Not Emblemized); Samples & Loops taken from other bands; the justification for this field is that it'll be used to decipher original from borrowed materials. I may utilize a loop of, say, the bass on 'Self Immolation (Vein Tap Mix)' by Fear Factory and invert it to create something new.
