What does empty trigs even mean. Do you really mean empty, if they are empty how can they have a lock ?
Do you mean the lock trigs have a note of zero ? If so, does this fall into the non-locked defaults that I discussed above, in this case it is not a lock nor significant and nor should it change pitch
Did you try what I said earlier, set the sweep Freq very close to default, do you perceive pitch changes. Are there pitch changes locked or heard/perceived
I also tried what you wrote, those steps are too vague tbh, but I don’t see pitch changes.
I explained two methods for The LFO locks (see note page) turn LFO retrigs off there and set a free LFO and set one LFO retrig at the start of the sweep. Long sweep LFO techniques are explored in the broader forum too
Record with filter 100% open and live tweak filter only in upper range e.g. 90-95% this will not mask the osc pitch. If you get actual note locks at zero, then this is a different issue.
