I have never calibrated the filter

But today I tried and after the procedure it sounds better.

How does it sound better?

I would like to know this as well.

With this being my first synthesizer, I often forget to calibrate the filter and I notice new tones and end up liking alot of them.

More finely, it’s difficult to describe, i don’t know if it’s for everyone, but on mine it’s not an imagination it’s real, i was immediately surprised.

Interesting. Maybe one of the UDO team could pop in and comment. Should we all be doing this?

The only difference I notice is the filter cutoff tracking the keyboard better when self oscillating, so can be used as a tuned VCO alongside DDS1, DDS2 and LFO1. Aside from that, I don’t notice any difference in timbre/fidelity.
