Hi Kai,

I see that running the engine for even one second is enough
for cop-status to report the LADSPA plugin latencies.

It will be very simple to parse that output and apply
the appropriate compensation using the Artificial Latency
plugin. I'll be putting that feature into Nama :-)

It will also help to know the latency associated with a loop
device. Can you tell me how it is determined?

Regards,

Joel
