KEYBOARD massive, huge, 100KG of analog circuits with black leatherette and optional chromed wonderful legs with music stand. Very colored at first glance, each color correspond to a precise functions: green is filter, red is resonance, white is pitch tune, grey is amplitude, yellow is sustain and black is all the rest.
Semi-weighted-action keyboard 61 (C-C) keys with superb velocity and polyphonic aftertouch, which controls also the LFO modulator (called strangely the Sub Osc). The volume and the filter cutoff (the brillance) can be also assigned to the keyboard using the "keyboard control" section. Did you say expressive instrument? on the left section the tabs allow to set various type of portamento with glissando (also assign to external pedal). If not enough, in the middle of the beast the famous PITCH RIBBON allowing incredible glides... at the fingertip!
->There are also two cheaper versions, but still with same CS sound: the Yamaha CS60 (8 voices single layer) and CS50 (4 voice single layer) Also a special modern remake called Deckard's dream but it seems also the low-cost Behringer plan to clone the CS...good luck
