this was probably the easiest feature request I've ever implemented.

... because it already works. :) Only thing I needed to change was the
ecasound-iam manual page that incorrectly stated that 'ctrl-select' et al
are not real-time safe. And of course, when replying to your original
question, I only checked the manual page, not the actual code. Doh,
sorry about that.

Yeps, currently you can only give one command at a time.

I've thought about adding shell type of way to concatenate commands --
something like "-kx ; ctrl-add -kos:4,1,5,0.5,0 ; start". Not a big change
in the end, and would be nice for some things (e.g. storing more complex
"transactions" in the command history in interactive mode). Hmm, why don't
I add a ticket for it... done:

#2132341 "Multi-command sequences in interacitive mode"
