A lock trig fires parameter changes without triggering a note

The step sequencer has two trig types: note trigs (fire a sample/MIDI note, shown in red) and lock trigs (carry only parameter locks, shown in yellow). A lock trig is created with [FUNC]+[TRIG] during Grid Recording. It lets you insert a parameter change at an arbitrary point in the pattern without adding an unwanted sound event — useful for moving a filter sweep to beat 1.5 without placing a ghost note there. Lock trigs participate in trig conditions and conditional locks exactly like note trigs. The common misconception is that parameter locks must be attached to note trigs; lock trigs allow parameter automation on any step, including rests.

Examples

Place a lock trig on step 5 (a rest in your kick pattern), lock the filter cutoff to 0, then place a note trig on step 7 with cutoff at 127 — the filter opens precisely at step 7’s hit without any extra sample firing on step 5.

Assessment

Describe a scenario where a lock trig is more appropriate than a note trig for a parameter change. What visual indicator distinguishes lock trigs from note trigs on the sequencer?
