[JW Lua] FCNoteEntry:PreviousInFrame()

[Jari Williamsson]

Pat,

Can you please check if the 64-bit Windows version of beta v.54 runs on 
your Finale 25?

Regarding your question about eachentry[saved], you should not use the 
"each" iterators to process data that is dependent on data objects 
earlier/later in the each chain. However you could store and "move" the 
duration values in the loop, similar to:

---
local currentdur = nil
local earlier_dur = nil
local even_earlier_dur = nil
for noteentry in eachentrysaved(finenv.Region()) do
    even_earlier_dur = earlier_dur
    earlier_dur = currentdur
    currentdur = noteentry.Duration
end
---

Another alternative would be to load and parse a FCNoteEntryLayer object.


Best regards,

Jari Williamsson
