Previously, when doing step 4, you had to paste the expert chart into the EMH sections before you ran the command. Now, that's done for you. You still have to adjust sustains and reduce chords.
Ok, so that's actually the latest improvement to the feature, which I suppose it only removes notes from Expert to H/M/E at certain times, so that they match the timings with 5LaneLeys H/M/E, but that's it. Well at least that's something.
In the CAT documentation there is also a mention of this feature:
But this is marked red in the doc, so I guess it's not yet implemented?
This would automate Step 2 in my list above, which as I said previously it would be very useful for me... I actually like charting ProKeys, but charting 5KeysLane is like a torture to me...
