Hey FP, figured you guys could help me out on this. i recently acquired a used d-50 from a local producer with 1 broken key and a little velocity issue on another, thats just an issue of dust, for 350. let me know if you think this was a good deal first. but also i came here to ask you if a usb to midi cable is all i need to send patches from my computer to my d-50. i cant post links yet or else i would. please let me know if i need something more, any details will help as well as im pretty new to synthesizers and midi. thanks !
