Using the ‘Save As’ button has the previously saved preset name in the browser, not the current name.
i.e. save as.. “Preset 1” and the name “Preset 1” appears in the name box ready to be saved
try again with e.g. “Preset 2” and the name “Preset 1” still appears in the name box
Ah ha… I was clicking on the preset in the hardware panel but not loading it - i.e. the preset was highlighted in grey, from a single click onto the sound, but not loaded (i.e. orange).
My mistake, I’d not realised they had to be loaded into the sub37 before being saved to the Mac.
