Hmm, -ev? Either a typo, or then I just don't understand...

Yup, this is a feature. A controller (like -kl) literally takes control of
the target parameter. You can use 'cop-set', but -kl will override your
change right away.
Have you thought about my multiple-chain approach to these on-the-fly
configuration changes? For instance, to do the above, you would have two
chains: a) with -kl, and b) otherwise identical, but without -kl.
These would be mixed to the same output. Now all there's left to do is to
mute the (b) chain while -kl is doing its thing, and then muting (a) +
unmuting (b) when you want to start using 'cop-set'.
Hmm, so basically the same technique as what dj's use. :) You have one
vinyl-player/chain for the online audio, and another one for preparing the
next track.

Difficult as in "doesn't work", or just "hard to use"?

This is unavoidable at the moment. Only implementation of 'c-clear' is an
offline version, so when you issue 'c-clear', all processing is stopped,
the actual 'c-clear, and then restart.
