Someone already tried a Dallas or equivalent digital pot or a filter
with digital corner frequency tuning? I need soft for these, any info
would be great. Thanks.

I've used the Dallas pots. Work as advertised. Clock and latch a setting

You may have to carefully monitor the linearity of each step though. My
project (computer controlled voltage) was quite forgiving.
