3x5

Thanks for all the thoughtful replies. I have some decent rechargeable batteries in my keyboard, from Energizer, and I find that my lights start flickering after using the keyboard on battery power, even in one sitting. So I end up keeping my keyboard plugged in most of the time. However, I have noticed that when I unplug it, the keyboard doesn't immediately go back to flickering, which leads me to wonder whether the batteries are able to recharge while inside the keyboard. If so, then that's great. My whole reason for asking about the l-ion batteries was that I didn't want to have to remove my batteries all the time and charge them outside the keyboard. Does this Casiotone recharge batteries?

Thanks for the replies. @IrreverentHippie, I'm not sure I understand your reply. I would only be putting them in my Casiotone. Also, if I put these batteries in, should I set my keyboard to the 'Nickel metal hydride' setting or the 'alkaline' setting?

When I was reading the manual for my Casiotone, it said I need to switch the settings with the function key depending on what kind of batteries I'm using. The choices were alkaline, and nickel-cadmium. Should I take this to mean I shouldn't use lithium ion batteries in this thing? If I can, what setting should I use?

I'm really happy with my CT-S1 so far. There are a couple things I'd like to do that aren't in the manual, so I thought I'd ask if I can use an app or send sysex messages to accomplish this: I want to replace a few presets I will never use (harpsichord, pipe organ, that dx7 sounding ep). I'd like to substitute some alternatives for those. I'd also like to replace the metronome with one of the VL rhythms, but that might be wishful thinking. Finally, i'd like to save some sustain and reverb settings to my standard presets (not tone memory). are any of these mods possible?

I clicked on this thread because I misread the title as "Tony Banks on CT-S1". Bummer!
