One of the very best drum machines ever. It has excellent sounds which can be expanded by adding additional sound cards (808 and 909 cards). Great rock, electronic, ethnic and industrial style drumkits! Most of the sounds are editable - tune, decay, attack, nuance, output, etc...But its coolest tricks are the Feel Patches which give your program a human-like groove! The sounds are ROM based samples, the R8 has 32 note polyphony, 68 instruments, 100 patterns and 10 songs! It is used by Orbital, Underworld, Jimmy Edgar, Autechre, 808 State, Dave Holmes, Fluke, Human League and The Shamen. GO TO THIS LINK TO HEAR ALL OF THE SOUNDS THIS AWESOME MACHINE POSSESES! /r8.html IT IS IN GREAT SHAPE AND ALL BUTTONS, SLIDERS, PADS, AND JACKS ARE FULLY FUNCTIONAL. THIS IS A NO EXCUSES LISTING. LOOK AT MY FEEDBACK AND BUY WITH CONFIDENCE!
