yeah, definitely! go to the settings page (will help to have this open: https://github.com/scanner-darkly/monome-mods/wiki/Orca#settings)
you can select settings for each trigger here, the confusing bit is - unlike CV settings rows here represent triggers, not tracks (easier to visualize if you think of the trigger outputs on the module), and for each trigger you select tracks horizontally, not vertically, like CV.
you also want to have AND and NOT logic off (so 3rd and 4th column unlit). this means that the trigger output will be fired whenever any of the selected tracks changes state. so if you want your trigger 1 to fire whenever CV A changes pitch just select the same tracks as CV A. hope this makes sense!
a neat trick to get 4 sequences with only 2 CV outs is to share a CV between 2 oscillators, but then shape their amplitudes with envelopes triggered by 2 different triggers, same for the other CV. and once you start playing with attack/decay values you get sequences that kinda flow into each other.
and try changing the trigger type (2nd column) for more variation, default is triggering on both positive and negative edge, but you can change that to positive only or gate.
