Hi all,

I am developing a higher level python interface to ecasound. I have collided
with the inability to set controllers to an effect after the -kx switch,
once more.

Consider the following test-code:
eca=Session()
ei=eca('ei', 56) # pitch shifter \

kl=ei('kl2',0,23, range_high=32) # 2-stage linear envelope
kl('kl2', 0, range_low=32)
ei('kl2',1,3, range_high=2) # <-- this can't be done!

I think that imposing on a possible programmer that you can't add
controllers to an effect after adding a controller-chain to it is restraining,
not to mention hard to implement sanely.

I think that imposing on a possible programmer that you can't add
controllers to an effect after adding a controller-chain to it is restraining,
not to mention hard to implement sanely. Ofcourse I could forbid controllers
on controllers altogether, but I think this would nullify the advances of
having this kind of programming environment somewhat.

So, what if we could have a new special switch, say, -ky? This would end
the controller on controller chain and return focus to previous controller
or effect. What do you think?
