On recorded music Archbishop Sample is at odds with the Vatican, the Conference of Bishops and his 2018 Archdiocesan Liturgical Handbook.
The Vatican in the Directory for Masses with Children (22 October 1973) has:
“32. … With these precautions and with due need and special discretion, recorded music may also be used in Masses with children, in accord with norms established by the conferences of bishops.”
This is from Chapter 3 of this document “Masses with Children in Which Only a Few Adults Participate”. In Chapter 2 “Masses with Adults in Which Children Also Participate” it has: “19. … Wherever the bishop permits, in addition to the adaptations already provided in the Order of Mass, one or other of the particular adaptations described late in the Directory may be employed in a Mass celebrated with adults in which children also participate.”
The Conference of Bishop document has (from Sing to the Lord: Music in Divine Worship, approved by the Latin Church members of the USCCB on 14 November 2007 at

Recorded Music
- Recorded music lacks the authenticity provided by a living liturgical assembly gathered for the Sacred Liturgy. While recorded music might be used advantageously outside the Liturgy as an aid in the teaching of new music, it should not, as a general norm, be used within the Liturgy.
- Some exceptions to this principle should be noted. Recorded music may be used to accompany the community’s song during a procession outside and, when used carefully, in Masses with children. Occasionally, it might be used as an aid to prayer, for example, during long periods of silence in a communal celebration of reconciliation. However, recorded music should never become a substitute for the community’s singing.”
Archbishop Sample’s 2018 (Archdiocesan Liturgical Handbook, Archdiocese of Portland, 2018 at
https://archdpdx.org/documents/2018/6/ALH First Edition REV - 3 June 2018.pdf accessed 31 January 2019):
“1.46.4 While recorded music might be used advantageously outside the liturgy as an aid in the teaching of new music, it should not, as a general norm, be used within the liturgy, for it lacks the authenticity provided by a living liturgical assembly gathered for the Sacred Liturgy. Recorded music may be used to accompany the community’s song during a procession outside and, when used carefully, in Masses with children. Occasionally, it might be used as an aid to prayer; for example, during long periods of silence in a communal celebration of the Sacrament of Penance. However, recorded music should never become a substitute for the community’s singing.”
Archbishop Sample in 2019 on page 18:
“4] Pre-recorded music may not substitute for actual musicians during the Mass. All music in the Mass is to be sung and played by musicians who are physically present as worshipers. If an organist or other instrumentalist suitable for the celebration of Mass is not available, it is certainly in accord with the spirit of the Roman Rite to sing the Mass in unaccompanied plainchant.”
