The chord symbol implementation is pretty good in Finale, except for one really large flaw. This is almost entirely for the person writing jazz arrangements, and an almost universal requirement in jazz chords is to provide chord symbols for solo instruments only in short passages, not the entire piece. The only way to accomplish this today, as far as I know, is to alter that PLAYER (not the instrument) to show the chords, then painstakingly select all the chords you don’t want to display and hide them.
It seems to me it would be a much more elegant and useful solution to select the display of chords (for non-rhythm instruments) at the INSTRUMENT level. That way, for the tenor sax player, I could have 2 instruments (section tenor sax and solo tenor sax) with the chords only showing for the section where the solo instrument is being used. Similarly, we would need a convenient way to show that solo instrument staff only during the solo section.
This approach would have the added benefit of putting the solo instrument on a separate mixer and VST channel. Typically I’d want to boost the solo a little, move it to the center, and maybe select a different sound that is more soloistic.
That doesn’t solve the more basic problem that it is extremely tedious to select chord names in the first place. I cannot find any way to select all the chord names for a particular instrument. Yes, you can marquee select everything and then filter down to chord names, but good luck with that when working on music with 100-200 measures.
