In the tide processor (the resynthesis engine) set it to ebb mode and turn up the harmonics dial. The higher it is the more consonant it is the lower it is the more dissonant/inharmonic it becomes.
In the glade engine (granular) set the churn control to a low value so it keeps reading from a lower range of the sample.
Set the Hold time to less than infinite or else you will get overlapping parts of the recording. Also set the sustainer recording length for the same reason.
This will result in more predictable tuning
