I believe pg. 108 in the pdf is what your looking for or “The Arranger”
It seems that you would be able to link up and entire song or even a live set like this. Up to 256 patterns in 8 possible arrangements.
Although
“CHAIN
Will make the arrangement selected in this menu start play immediately after the currently playing arrangement has finished playing. It has a similar function to pattern chaining, with the exception that no more than one arrangement at a time can be chained. The chained arrangement will be visible in the default arrangement screen, located after the last row of the currently active arrangement.”
This chain limitation is huge if you plan on using it live.
Or is there a way to get around this, I do not have an OT in front of me but I’m pretty keen on getting one after I read the manual.
Pretty well done the manual and id have to say it is a little dry and somewhat of a roundabout in places, but well worth the read.
