Thank you for viewing. I am selling the KORG PCM expansion board, EXB-PCM05 "Vintage Archives." It can be used with their TRITON, TRITON-RACK, and KARMA. This expansion sound board contains vintage sounds from the company's past products and both domestic and international vintage sounds, including 128 programs of synth bass, leads, pads, synth strings, and rhythm machine sounds, as well as 158 multisamples and 56 drum sounds. The capacity is 16 megabytes. I used it with a TRITON-RACK. I will include the included floppy disk (PCM/PERFORMANCE DATA LIBRARY EXBPCM-05FD) with the PCM board itself. Please download the instruction manual and KARMA data from the KORG website.
