Bob, sure we disagree, not about possible fixes to software, but over your claim that if this were done it would be mean less button pushing, which for the problem under discussion is clearly not the case compared to a solution I've suggested now.

Walt, did you prime both apc and control tracks? All you have to do is dial up just before the ending and punch in knowing the measure and the chord. Auto punch is even easier and foolproof and can also be dialled in. I can delete any ending in 2 seconds using this method. The great advantage is that if you have any melody/counter melody that overlapped the ending, these remain untouched, and if wanting to repeat you just repeat from the next measure with the melody intact but no ending command.

The next easiest method without using step record is measure erase since you can dial up the specific measure and set the data range to control only. Do this on tracks 5 and 6 of an easy recording and it takes me about 3 seconds and again leaves the melody untouched. The only point I'm making is that if your ending is in measure 100, then step record will require another 100 button pushes to get there, something that can be easily avoided by knowing how to use the full facilities on offer.
