There is no “track default”. When holding the TRACK button, you gain quick access to the current pattern’s length.
To change the length of multiple patterns within a track, you might want to use selections in PATTERN mode.
I would very much like there to be a way to set up in the misc settings menu, a line for "starting track length: 16, 32, 48, 64, 128, 256, 512… Now of course, there are the cultures that don’t observe duple divisions, but triplet divisions, like most of the South American Andean folk, that stretches from Ecuador down through Peru and Bolivia, and finishing both sides of the andes, in Argentina and Chile. All of which observe 3, 6, 9,12 sets, in their quarter note subdivisions.
This is why I would opt in favor of having it be a freely single digit numerical choice, rollling the main encoder through the “Starting TRACK step length,” where all the machine updates.
I will send you a case of Argentine wine if you push this up to the senior developers. We use 3 divisions per beat down here, not 4!
Just messin’ with ya. This machine is a miracle box that still hasn’t been discovered yet. Dominates all other Out of the Box sequencers.
