Christophe; I also thought about converting presets from one element to
another. Unfortunately I don't see a way to support this in a generic way and
also not part of the preset support. I have a similar problem in buzztard.
There I have pattern with music events. If one receives a song, wants to load
it but misses an effect, the user might want to use something similar and this
nees mapping the parameters. Also the musican might not be happy with a sounds
and replace one effect with a similar one. For this me need a mechanism to
install a->b transformers for specific elements.

One thing I could do in the equalizer is to remap the gain-values when the
bands change. Right now bands is construct-only and I want to change that
anyway. So you can load any preset and just reset the number of bands to 3 or
10 afterwards.
