Hi Tony,
I don’t know for sure that this will work but if it were me I think I would load the song, pick some style that is in 2/4 time and assign it to replace your original style. Do a panel write of the song and new style, (2/4), play the song and note the measure to remove, (it should now be a measure in 2/4 instead of ½ measure in 4/4), then go to the sequencer, delete the measure in question, (all tracks), then re-assign the original style and play it to see if everything works.

As long as you don’t save this to the original disk, you will still have your original effort and if things don’t work like you want, maybe someone else will have another solution. Good luck!!!
