Long ago, I downloaded a file by Markelford, GPO Midi Filter, and Midi File Translator. I have not used them in a long while, because I write mostly piano and organ music, where such things are not needed. However, lately, I have been working on a moderately large work for string orchestra, and neither of the two work now. Were they designed strictly for the GPO Studio, which also no longer works (which makes me VERY UNHAPPY)? Or am I missing something? I have a mod wheel on one of my keyboards, but I have never used it, and would really not be amenable to re-entering all of my music using a mod wheel, the idea of which turns me off.
Can anyone advise how to restore functionality of the filter? I was given a solution for restoring the GPO Studio, but it was rather detailed, and I was concerned about botching the operation, so I did not try it.
