Snippet for basic parser of cakewalk instrument definitions. I’m not a programmer so feel free to point out any bad syntax 
It currently supports Bank Select method 3, and should provide all data needed to browse patches via midi messages.

file_data = { } – for better and more efficient handling of the files data?
file_data_delimiters = { } – for finding delimiters using table.find

if method == 1 then – method 1 filter recognizes the patch value later being used to derive control messages for bank change
return string.sub(input, string.find(input, “%[”)+1, string.find(input, “%]”)-1)
elseif method == 2 then – returns msb from patch value
return math.floor(input/128)
elseif method == 3 then – returns lsb from patch value
return input%128
elseif method == 4 then – returns the name of the bank
