I use PSPad (great freeware text editor) and have made a template that shows up the various bits of code in pretty colours. You are welcome to a copy if you want it.
The simplest way to do it is to use a unique string and then for each voice file copy then use global replace.
.tx $F0 $0F $05 $00 voicenumber $01 0 12 1 val12.13 val8.11 val4.7 val0.3 $F7 (I'm still not sure what the correct tx you are using)
Search & replace "voicenumber" with $00 $02 (Feel free to shorten the unique word vox perhaps)
Always edit the 'master' copy with "voicenumber" in it. It means that you have to copy the file and do the global replace then load it into the editor, but hey, that's the joy of it.
I would have two files open in PSPad. The master and the one for voice 1. CtrlA to select all the text in the master.bc2, CtrlC to copy. Tab over to voice1.bc2 CtrlA to select all in voice1 CtrlV to paste over the highlighted stuff ie replace all with the new edited stuff.
Search & replace all instances of "voicenumber" with $00 $01 . Save the voice1 file
Alt Tab to flip over to the BC editor, load it in and send.
Test away
Mark's editor may have a better way of doing this, bit I'm not good enough at using it to help you there.
All the best
