Casio CT-510

Released in 1987, the CT-510 is the full-sized relation of the MT-500 and MT-520 mini keyboards.  The immediately distinguishing feature of this particular family is the group of large drum pads on the front panel. Less obvious are rear panel inputs for a pair of DP-1 external drum pads, with an additional input on this model for bass drum pedal. Additionally, there are front panel sliders which allow you to change – or turn off entirely – the various drum sounds in the auto-accompaniment. You can, for example, turn off the snare and trigger it manually using the front panel pad.

Left-side controls include rhythm selection, accompaniment type, a fill-in button, part volume controls, and the aforementioned SuperDrums (!) slide switches.  Keeping in mind the standard level of expectations for any Casio product, the drums are pretty good. The ability to change the various parts even while playing is a definite plus.

The right side contains the tone selector, and the minimalist sequencer controls.
