I wrote a script in Lua to check MIDI files for consecutives. It assumes one voice per track, so may not suit your needs for figured bass. I need to make it more user-friendly, but would be happy to do so if anyone is interested.

Congratulations to Thomas Tallis for having no consecutive fifths at all in Spem in alium!

Maybe somebody already made a script for this:

In figured bass there are two fundamental rules: Avoid parallell octaves and or fifhts.
So it would be nice to have some scipts what checks for this. So if two voices have a distance of a fifth or octave, the next chord is checked if the same two voices have a fifth or octave too. If so, they are parallel.

Any ideas, suggestions?
