Richard. Thank you for answering my queries. I don't really understand the terms "memory circuit", or "memory back-up capacitor"-or "non-volatile flash- memory".Would it be too much to ask you to give me a quick definition of these terms,please.I was just quoting the Roland manual which like all manuals, assumes you know as much as they do.
I understand that panel memories etc may disappear if not saved- but the functions on the Roland that are diminishing is the control of brightness on the display screen - turning the control knob makes no difference and the tempo wheel is not responding -sometimes increasing instead of decreasing etc. Do you think this is due to weak battery or "wear and tear".There is another feature called "performance memory hold" which is not on a Technics that is also not functioning properly. I thought that as all 3 features seem to be weakening at the same time it must be the battery, but maybe not? I would appreciate any advice. Although it is a Roland problem I would like to understand the workings of each keyboard otherwise comparison is difficult, and I am trying to get a grip on all this technology. Thank you Reguards Jean.
