[solved] First trig on some OT patterns "fades in"

On some patterns in my current OT project, the first step/trig seems to have a short fade in at the beginning that I cannot get rid of.

I have copied the trig to other steps in the pattern and they work fine - only the first trig fades in. Also, wenn I stop playback and then start again, the first trig plays as it should, but only once.

Can anyone please tell me what’s going on?

can you upload a single pattern project as an example?

Well… I’ve found it. Thanks to your suggestion, I’ve tried to recreate the behaviour in a new project by duplicating every parameter setting of the track in question. Turns out I had an LFO routed to the filter cutoff frequency, but with the depth parameter turned up so slightly that I couldn’t see it from looking at it. So - thank you!
