Hi Kai,

I guess I was suprised that that setup length
reported by cs-get-length ('length of the chain setup'
according to man page) wasn't the length of the
'longest input object' (used by cs-set-length).

I would expect 'length of the chain setup' to be the same as
the length of (audio) time the engine will run.

Here is a possible clarification of the current behavior
for 'man ecasound-iam':

       cs-set-length 'seconds'

       Sets processing time in seconds (doesn't have
to be an integer value). A special-case value of '-1'
will set the chainsetup length to the longest input object,
### however will not limit processing time if the
### chain setup under includes a device input.

I appreciate your care in answering most every question
posted. :-)

Joel
