Thank you for viewing. I am selling the KORG PCM expansion board, EXB-PCM09 "TRANCE ATTACK". It can be used with the TRITON, TRITON-RACK, and KARMA series. This is an expansion sound board for HOUSE and TRANCE music, containing 128 programs of synth basses, leads, pads, detuned sounds, drum sounds, etc., as well as 78 multi-samples and 240 drum sounds. The capacity is 16 megabytes. I used it with a TRITON-RACK. This listing is for the PCM board itself only. Please download the floppy disk data and instruction manual from the KORG website. https://www.korg.com/us/support/download/software/1/278/3342/ https://www.korg.com/jp/support/download/product/1/50/ There are almost no scratches, but please understand that this is a used item before considering a purchase.
