OTS setting are saved & included as part of a 'style'. You can though, save settings stored in a 'currently selected' OTS button (1-4) by first calling up a style with OTS, selecting one of the 4 OTS buttons, and then select the 'memory button' followed by any one of the 8 reg buttons you want to save the currently selected OTS button's settings to. It's important to make sure the 'Memory Contents' checked boxes include all of the OTS setting parameters you wish to be included to be saved into a reg memory. Hope this makes sense. - Scott
