Thanks to Roman to alerting me to some youtube videos of the recent ACSA Conference, and providing some background on liturgy at the Conference.
Three Masses were said in the ordinary form and one was said in the extra ordinary form.
On July 10th there was a votive Mass of the Holy Spirit for the opening of the conference said in the ordinary form, verus populum with the benedictine arrangement, the introit was sung according the Anglican use gradual.
Later that day, a votive Mass of the Blessed Sacrament was sung in the extraordinary form, which was followed by Benediction and all night adoration.
On 11th of July, there was the reception of the Icon of our Lady Seat of Wisdom and a votive Mass said in her honour by Bishop Geoffrey Jarrett of Lismore Diocese, ad orientam, with the introit likewise sung according to the Anglican use gradual.
Finally, on the 12th of July, Bishop Jarrett again celebrated Mass ad orientam, this time with all the propers chanted and the asperges sung from the Anglican use gradual. The General intercessions were also chanted.
Here is the video of the Extraordinary Form Mass as a taster:
