MPC IRREGULAR BAR? 2/4 ON 4/4 SEQ

Hi guys! Im composing a new song, but i have a problem with the first sequence. I need the last bar with only 2 beat. I was looking for information and i found the next opinion of a forum member. This is the post;

viewtopic.php?p=473038

And he said:

the easy way to insert two beats (a half bar in 4/4) in a Sequence is to do this:
In MAIN screen, put the cursor on the time signature field (where it says 4/4 by default), then hit WINDOW. This shows you all the measures in the sequence and their time signature.
Move the cursor to the measure where you need the two extra beats, then put the cursor on the top number and change the 4 to 6. Hit MAIN to go back to MAIN screen. You will now have a measure running 6 beats instead of 4.
Anothe option is to add a measure, and set it to 2/4 signature, but it takes slightly longer to do.


So, can someone explain me with other words what the user tried to explain? Cause i cant found the "time signature field" and i don´t understand when he said "hit window", what window?

Thank you very much, your advice is very helpful for me!

duplicate the Sequence and adjust the New Sequence to whatever length you want. And just bring the New Short Sequence in on the last bar of the Song

It's not really clear what you want to achieve. It would be better if you could explain that. But it seems like 40beatz gives the easiest option, if I understood correctly..

Or make a new sequence with your 2/4 bar, then go to song mode. Put the 4/4 first and then 2/4. Then convert to new sequence.
