Yarns Arpeggiator Problems

Hi there, my Arpeggiator seems to have stopped working, as soon as the arp range is set to 1 or above i get no cv out of it, there are no other problems with the unit and have tried reinstalling the firmware to no avail, anyone had this problem? or am i being very stupid and not changing some very basic setting? it was working like a dream yesterday, i just want to make sweet arpeggios. bah.

What is the value of the TE (MPO) setting?

That was quick, tempo is 120. Sequencer works fine, midi input is output as cv on all modes, its just the arp that won’t play ball.
