Up to this point, I have only been reading in delta times using variable length values in my program. I see glancing through documentation that lengths of other things can also be represented with a variable length value.

Which items should I be checking for a vlv with? I don't think I've run in to any issues with it because generally most thing will fall in the less than 128 range, but I want to do everything properly, so will need to add in scanning any other vlvs correctly besides delta times.

Opening the Standard MIDI Files specification PDF and searching for instances of the word "variable", I confirmed that the following items are variable-length quantities:

• the delta-time before each event

• the length value in System Exclusive events (F0) or System Exclusive packet/Escaped events (F7):

F0 <length> <bytes to be transmitted after F0>
F7 <length> <all bytes to be transmitted>

• the length value in all meta events:

FF <type> <length> <data>

My reply seems to have vanished?

Anyway, thanks, I will be adding these in. Every little bit brings me closer to finally being done :p
