[Ardour-Users] Ardour 3.0 beta 1a - Plugin levels 6dB higher than 2.x

This may be a feature rather than a bug, but it is puzzling me. I have a 
session set up in Ardour 2.8.11 on Ubuntu 11.10 to do Ambisonic UHJ 
decoding. This uses instances of Tom Szilagyi's IR convolver plugin to 
do the conversion of UHJ to B format. I have duplicated this session 
using Ardour 3.0 Beta 1a. Using exactly the same level settings in the 
Ardour mixer and in the plugins wet and dry settings, the overall level 
coming out of the plugin and showing up in the mixer meters is about 6 
dB higher than that which I get in 2.8.

Has anyone else observed anything like this? Have I missed something 
obvious in the new UI? Has anyone got any ideas what is going on? It 
just does not feel right to me to have drop the wet level in the plugin 
by -9 db to leave some headroom for the rest of the conversion process.

By the way the multichannel export support in 3.0 is awesome for playing 
with Ambisonics etc! Keep up the good work guys.
