[PD] Questions about midi-volume abstractions

Hi list:
I'm working on a big diffusion patch, so I made some volume and midi
abstractions (I'll need a lot of midi controlled volumes).
raf_volume.pd calls raf_BCF2000.pd (I have this midi controller, of
course it can be used with every midi CC signals...). Arguments as
following: start value, end value (scale), CC, channel.
I'm using Pd-ext 0.42.5 on Ubuntu Studio.
My questions:
-I noticed a (kind of) bug: when I instantiate a [ctlin] object with one
$ as argument (CC number), no problem, but when I add a second (channel:
[ctlin $1 $2]), second outlet doesn't disappear, and if abstraction
window is opened, pd becomes unstable. It crashes sometimes when I save
the patch calling the abstraction, or saving abstraction itself
(ctrl+s). No problem with numbers as arguments.
-When I instantiate raf_volume.pd, I enter arguments in the object box
(CC, channel), but I didn't find a way to change them after. I could use
externals [number2\, but the patch will become really heavy, or display
name and arguments in "graph on parent", but the object becomes to
big... In the same idea, I wanted to keep the sliders position (init),
but it doesn't seems to work in an abstraction...
-If you have any suggestions about these abstractions, their performance
etc, you're welcome...
Thank's a lot
best
