Hi,
As far as I'm aware, I believe that OTP is mentioned on the Technichord page, because some of the OTP settings that the KN bring up, will include the Technichord turned "ON", therefore it is mentioned on the Technichord page, should a new user notice the panel light on, and not know what it refers to.
I'm not totally sure what you mean by settings you have previously saved on OTP, as only in the Custom rhythm section are you able to create your own OTP settings, however, if you for example, pressed OTP on the "House" rhythm, and saved it in a panel memory, then you choose another rhythm, and press OTP, you can recall the "House" OTP by simply pressing on the appropriate panel memory button.
Hope this helps, and I haven't got the wrong end of the stick!
