I could guess that there are two routines
with conflicting quoting conventions.

Perhaps Ecasound could be more liberal about quoting.

There is the IAM command, cs-save-as 'filename'.

man ecasound-iam

Yes, maybe Ecasound will have a way to represent it for the
platform. I expect you're not the first person to
attempt this. :-)

The ECI interface (using the same commands described
in 'man ecasound-iam') is a third way to
configure and manage the audio engine.

Nama uses a combination approach: the signal routing for
a setup gets written out as an .ecs file, and after
loading it, effects are applied by sending commands using
Ecasound's Net-ECI inteface.
