Yes, DPF is a good example. It takes care of a lot of details for plugin
development in general. Kudos to Filipe 'falktx' Coelho.

The Harrison XT-* plugins are native Linux LV2s. The DSP is also not
license encumbered: The plugins work for existing sessions and also with
the generic UI. You only need to buy a license for the custom GUI.
They're still closed source. YMMV.

I'm curious what you find.

In general multiband-compression is used for mastering or to improve
intelligibility. For those use-cases phasing issues or harmonic
distortion are usually the opposite of one wants. In fact cross-over
stages introducing artifacts is the main reason to try to avoid
multiband compression.

If you want to use the effect artistically, calf may even be preferable;
but that is subjective territory.

have fun!
