Hello Kurzweil users, I've assembled a K2000/K2500 CDROM consisting of about 60 instruments (total of 108 Meg). It includes woodwinds, brass, strings, keyboards, guitar, drums, perc, synth, basses, effects. Almost all the instruments on this CD are from sample playback units of the 80s and early 90s. Just the best patches--the ones that you could play over and over and not get tired of or sound fake. Most of these instruments, if used properly, will fool you into thinking they are human beings. This is a good CD to beef up your K2000 internal sounds, without having to buy a ROM board from Kurzweil. The CD costs $20. Woodwinds: flute, alto flute, pan flute, bassoon, oboe, clarinet, soprano sax, tenor sax, bari sax, blown bottle Brass: trumpet, muted trumpet, muted trombone, pop brass section Strings: solo violin, solo viola, solo cello, solo double bass, arco strings, pizzicato strings Guitar: acoustic guitar 1, acc. guitar 2, acc. guitar 3, 12 string guitar, humbucker, gibson, grunge, muted guitar Keyboard: yamaha electric grand, wurlitzer electric piano, rhodes "tine" piano, SY77 rhodes (2), celeste, DX-7 rhodes Drums: acoustic drum set (large) Percussion: congas, timbales, latin, cowbells, ethnic, shakers, woodblocks, rap, clap, tambourine, triangle, antique cymbals, effects Synth: several analog and digital synths Bass: fretless, pick bass, synth basses Other: concert harp, sitar, choir, marimba This CD is fully backwards compatible (will work with K2000s with older operating systems) Visit my site at http://home.pacbell.net/melkjer to hear an audio clip, and for info on how to get the CD. Thanks, Bob Elkjer
