Pattern plays twice on starting a row

[XORadmin]

This is expected. Startx2 queues a pattern to launch on the next checkpoint, so when you press start for the second time, you're queuing up the pattern to play again before it moves on to the next.

While playing, pressing start on another selected pattern will trigger the pattern to play after the last pattern of the same column finished it’s sequence. Pressing START 2 times, will trigger the next pattern faster, after an amount of steps, set up by the Project setting ‘Live Quantize’, derived from the main 64 step clock. You can see the next point of the starting point on the top and bottom Base Clock Indicator. 

Yep I'm talking about starting from the stop position and not expecting all the tracks playing the first pattern twice regardless of how many steps in each pattern and quantised steps.

At least I know must stop the nervous stabbing at the Start button when starting a project.

all good

Still also from stop it is exactly the expected result. On the first press of start you start the patterns and the sequencer. And with the next pressing of start you tell the playing sequencer that it should play the selected (in your case the patterns where you are right now) next. Which is then the same pattern again as you selected it to play next with the 2nd start.
