This is a two-CD set of sampling sound effects collections, "demo 2000" and "demo 1999," released by Discovery Firm. It contains a wide variety of loop素材, instrument sounds, and sound effects from genres such as hip-hop, techno, jazz, and R&B, with 98 tracks on demo 2000 and 97 tracks on demo 1999. In particular, the sounds of vintage rhythm machines and bass synths like the TR-808, TR-909, and TB-303, as well as historical Roland and Korg sound sources, have a vintage quality that is highly valued in current music production. This is a rare item especially recommended for trackmakers looking for sampling sources, for importing into samplers (AKAI MPC, ASR-10, etc.), and for sound creation in DAWs. Product Condition: Due to the nature of this demo sound source, the front jacket (booklet) was not originally included, and the packaging consists only of the index card on the back. There are no noticeable large scratches on the discs, but please understand that this is a used item before purchasing. No individual sales. Instant purchase without comment is welcome.
