the plugin has a latency of 12.5 ms. This corresponds to about 552
samples at 44.1k, 600 at 48k. Not sure what happens when the freeze is
issued in Ardour, but IIRC it seems to work normally during regular
playback (I don't use freeze, and I am far from Ardour ATM). So it may
be a bug in the Ardour freeze code related to plugin latency

FYI, the existence of this latency is noted in the plugin manual at
in the section "Summary of user controls".

Hope this helps. Sorry for the late answer.
