Progress line

Quick question: on my 2500 (running JJ 3.10) there is no line that move across the waveform as a sample plays (I can't recall what this line is called at the moment). Is this normal on the 2500? This seems like a very standard thing and would make editing samples way way faster. Any help is appreciated. Thanks kindly.

"play marker" is what you're looking for.
Have a look at the jjos comparison chart....it seems like you need jjosxl....

cheers
