I have a custom style 3/4
When I change the variations, the rhythm doesn't wait for the bar to complete but rather changes in the next beat.
This is hampering the overall flow of the song, especially as I have a lot of registration changes to make.

How to make the change wait till the current Bar is complete

I will try to illustrate with the best I can.

Present scenario:
Variation A - 1-2-3 | 1-2-3 | 1-2-3 | 1-2-3 |
                     (♀)
                      Press Variation B at Beat 1
                        Variation B starts at the 2nd beat of the same measure.

Expectation:
Variation A - 1-2-3 | 1-2-3 | 1-2-3 | 1-2-3 |
                     (♀)
                      Press Variation B at Beat 1
                             (♀)
                             Variation B Should start at the beginning of the next measure

Next variation will start at 1st beat of the bar if you change variation before bar of the current variation ends. That is, you need to change variation before the next bar starts.

If you change variation just after 1st beat (and before 2nd beat), then the next variation will start at 2nd beat -see this as an emergency solution in case that we're a bit late at changing variation.

If you change variation anytime after 2nd beat, then keyboard will play current variation to the end of the bar and start next variation at 1st beat.
