"...do you use the trigger outputs and for what purpose?"

They work great for glissando's of course, but I mainly use this 
feature in conjunction with the A155's glide function. It can insert 
notes in-between the clock pulses, creating more complex rhythms than 
possible with just a step sequencer.

If you're careful, you can make this work using the pitch CV. Much 
more control is possible, though, if you use the second A155 track as 
a dedicated glide/trigger controller.
