Volume replacement in MIDI files?

Any suggestions on how to bulk replace a specific volume in a batch of MIDI files?

Every game I am converting for my SNES MIDI Remaster Project is presenting it's own unique challenges.

In the previous game I completed, I had to boost the channel volume in the converter by 45 for all instruments to be audible.

In the current game I am working on, I have boosted the volumes by 30, but am now finding that the sound engine in this particular game does not end a note if the original volume is set to 0. By boosting everything +30, those notes now do not stop until the next thing is played on that channel.

Any suggestions on how I can easily bulk replace Channel Volume of 30 with Channel Volume of 0? If I can do this, the other volumes will remain higher as needed. Otherwise, I will either have to manually add an earlier Note Off for anything that is supposed to go to 0, or scrap the +30 boost all together, which will give me some very quiet MIDI files.

If you are not afraid of hacking with JavaScript, try this: https://github.com/jazz-soft/JZZ-midi-SMF
Read MIDI file, add/modify/delete any particular message, save it back.

I had a quick look, and quite truthfully, though I have plenty of programing knowledge, Javascript has never been part of my repertoire. I can't wrap my head around how to do anything with your software except for things you have very specific instructions for :p
