All I can suggest is to check all your Apps and see if any of them are taking up an unusual amount of space. I don't have my iPad with me as I'm writing this but I think there's a way to have the iPad show you how much space each App is using.
Yes, there is...
- Settings
- General
- iPad Storage
It may take a few minutes for the list of apps to finish populating and for their memory usages to be shown. They will be in descending order by their memory usages. If you select an app in the list, it will show how much memory is used by the app itself and how much is used by the app's related data files.
Be cautious using the "offload" or "delete" options with any apps you really care about, as they might not be able to be reinstalled at a future date if you update your iPad's OS and the developer doesn't update the app to meet any new compatibility requirements of the OS version.
Thanks for all this good information.
After struggling with Yamaha's confusing guide I finally figured out how to change the CP4's 'performances' with OnSong. For others searching for this, when you edit an OnSong song you can add MIDI: 63.80:115 where 115 is the performance number minus 1. So 115 is actually performance 116.
There are other things I'd like to do like adjust the volume of a part per song, but I have no clue how to even begin with that. Specifically, if I have a split, say bass on the bottom and organ on top, I'd like to be able to reduce or increase just the organ volume for a particular song. Song A might have the organ a little quieter, song B might have it a little louder.
Do you know if this is doable?
Yes, and yes.
Second "yes" first:
Yes, you can use the Channel Volume message to set the volume of a given channel. I forget the CC number, but I think it's something like 10 or 11. You can look it up in just about any online MIDI reference; I'd look it up myself, but I'm replying on my iPad, and navigating away from a reply that's in progress can lose any part of the reply that hasn't been auto-saved yet.
Note that the CC message is usually referred to as just "Volume," but it's a channel message, so I'm calling it "Channel Volume" to distinguish it from the "Master Volume" SysEx message.
However, if you are selecting performances, you might need to set the part volumes on the keyboard itself within the performance and save it. If you're using the "same" performance for different songs but want to have different part volumes for each song, you might need to set up and save multiple performances. It can depend on whether your keyboard allows you to associate and control a given keyboard part with a given MIDI IN channel, or (if that option isn't available) whether you have the keyboard's Local Control turned off and are using an app on the iPad to echo the keyboard's MIDI output back to the keyboard to be sounded.
First "yes" second:
Yes, Yamaha has an unfortunate habit of publishing lists of voices and performances where the Program Change values have been increased by 1 to conform to the "humanized" 1-128 numbering scheme, even though the actual Program Change values within the MIDI messages must conform to the 0-127 numbering scheme. And Yamaha isn't the only company that does this; even the MMA (MIDI Manufacturers Association), in its infinite wisdom, does this in many of their online listings of the General MIDI sound sets! And DAWs and other software can confuse the issue even more by whether or not specific programs or apps use the true 0-127 numbering scheme or the 1-128 numbering scheme. Some programs, such as Ableton Live, might even use the 1-128 numbering scheme for the Bank Select MSB and LSB values! I think it's insane, but I don't get to make the rules and tell the rest of the world what to do, so all we can do is be aware that there are two different numbering schemes, pay attention to which numbering scheme is being used by which hardware and by which software, and then add or subtract 1 to adjust the Program Change values as appropriate-- and, if necessary, do the same adjustment with the Bank Select MSB and LSB values, although as far as I know Ableton Live is the only DAW that requires it.
The exact same situation exists with the MIDI channel numbers, which are 0-15 inside the actual MIDI messages, but which seem to be universally referred to as 1-16. But again, this can depend on the hardware or software, so all we can do is be aware of the situation and pay attention to which numbering scheme we need to use with any given hardware or software.
