I need to quantize a sequenced drum track in the CTK 6200 keyboard and the manual is utterly confusing. It tells me to enter edit mode then press the Qrantize button to enter the quantize screen. I did the 15 times and nothing happens when I follow this procedure which is found on page 89 in the manual. Can anybody help me with this? I have a project that I must finish by Friday and I am stuck in the mud.
