I think you can adjust the "PW" on both ends on the sequencer in regards to up & down, but not sure how much adjustment there is from 1100 (1.10) and 1900 (1.90). The instructions mention something about it, and may be worth seeing how far you can raise or lower on end so the sequencer will operate in narrower pulse width spread so you can utilize the middle as one of the trigger points.
