The statusbar always uses "live" playback data. I guess there could be a special case if the finetune command is right next to an instrument number, but in all other cases it won't be possible to show the "correct" finetune range.

Oh right. Well then, I suggest adding that special case, it would still be an improvement even if it doesn't cover all cases.

It would be a good idea, yes - the code that is responsible for displaying effects isn't aware of the other cell entries like the instrument number. This might be tricky to implement.

Another idea: how about displaying it without the unit when the song is stopped?

So for example:

• PB range = 1, Song is playing/paused: -128 cents ~ 127 cents
• PB range = 2, Song is playing/paused: -256 cents ~ 254 cents
• PB range = any, Song is stopped: -128 ~ 127

Additionally, the fact that the "unit" is displayed as cents can be a bit misleading; people might confuse it with 1/100th of a semitone when it's actually 1/128th.

I suggest changing the name to something like /128 semitones (e.g. +C0 becomes 64/128 semitones),

or maybe converting the value to cents when displaying it (e.g. +C0 becomes 50 cents or 0.5 semitones), or whatever you think that makes more sense.

It's the same issue - the code simply doesn't know whether the song is playing or not. It receives the information about the current channel state but that doesn't contain any information on whether playback is running or not. That would be more difficult to figure out than the surrounding instrument information, probably.

Managed to sneak some instrument information into the effect name formatting in r16338.
