i just bought a korg concert series piano in the black market for approximately USD220. initially i thought it was similar to O1W, (88 keys except with only 5 voices, with midi input) but when i was looking for the pedal input, i couldn't find any. so i searched the net and i noticed all concert digi piano's has built in stand and mine doesnt. to my horror, i realized... it must have been too bulky so the legs we're cut off. so now...i don't know how to attach a sustainer pedal to my keyboard. =( its a c16 model...and i couldn't even search where it was manufactured. help anyone!
