Cannot open .BTM after reopening BambooTracker

[djtuBIG-MaliceX]

Hi,

Was working on something for a couple hours. Not sure what happened but all of a sudden I am no longer able to reopen my .BTM file as it appears with an error:

I have attached the relevant .BTM file in the following zip.
djtBMX_BTM_bug.zip

Not sure what could suddenly cause this but I suspect it might have something to do with deleting and adding instruments?

Thanks,

Thanks for your report.
It seems the same unknown bug with #44. Instrument index of Instrument 01 (Oboe) was set as 0xFF not 0x01. I attached the fixed file.
fixed.zip

it might have something to do with deleting and adding instruments

I think so too. Did you delete Oboe and undo it?

[djtuBIG-MaliceX]

I may have yes. Though I just add another instrument afterwards which then fills the index gap.
It certainly sounds repeatable if the instrument list is suddenly mapping to a default value 0xFF presuming it's a default constant. Happy to investigate a repeatable test case.

Also thanks for fixing the .BTM

Although I didn't know why it happens, in 758c350, I removed code which set a instrument number to -1 (0xFF). -1 was a flag as "this instrument is not registered with instrument list". I divided the flag and the instrument number, so I think it would not occur to set wrong instrument number.
