Well, I don’t mean to grift, but you might want to take a look at some of my arrangements, where I base the melodies on Gregorian chants: www.psallitedomino.com (and YouTube: “ServiamScores”) I only have a fraction of my output currently posted, but if this is something that interests you, I can provide you with more.

Also tooting my own horn here, but my SATB settings can be found on the Chabanel Psalms website (under my own name, Sam Schmitt).

The choir of St. John Cantius Church in Chicago sang them during Holy Week 2022 under the direction of Massimo Scapin:

Palm Sunday: Psalm 22 | score

Easter Vigil
After the First Reading (option 2): Psalm 33 | score
After the Third Reading: Exodus 15 | score
After the Fifth Reading: Isaiah 12 | score
After the Seventh Reading: Psalm 42 | score

Wonderful, thank you! And for everyone else reading, please feel free to "toot your own horn" with linking your own responsorial psalm compositions!

Here are a few examples of my "chant psalms" (ie– settings that take direct, overt inspiration from gregorian melodies)

123: https://youtu.be/-xJ03HoykRw (I should mention that in a few cases like this, it is possible to sing them SATB to the harmonies of the organ accompaniment, and I can whip up versions that are notated appropriately.)

I also have a few interesting gospel acclamations based on chants, such as my "Alleluia Rorate Cæli" https://youtu.be/sF3uz0ypv-0
as well as this lenten one which is based on the chant that says, "I will meditate on your laws..." (appropriate for right before the gospel!) https://youtu.be/tGrSAlvtLsQ
and finally my "Alleluia Peregrinus" which is great for funerals or penitential seasons: https://youtu.be/H9xmEdped40 (this recording is melody only, but we sing it SATB as a choir).

>As an aside, here's a fun Advent Alleluia for Gaudete Sunday based on Genevan 42: https://youtu.be/prc1irTIo1g

Lastly, here are a few examples of my "regular" (ie- not based on any particular gregorian melody) psalms, of which I have probably a hundred settings:

David, you need to generate actual share links, not just copy the url as you view them when logged in to your own account. The links (to individual psalms) are currently broken. For instance, this is what I get when I click the share option for your Ash Wednesday psalm (which I quite like, by the way!): https://drive.google.com/file/d/1S5QMSd9S1WW_Z028bDo6u9Heu9622cl7/view?usp=sharing

Sam Schmitt, thank you so much for your work, and beauty you bring to the Foretaste of the Heavenly Banquet. I have known of your work, for years, but in the last two, have finally had a couple singers capable enough. We are using some of your psalms every other or third week, now.

My cantrice is still of the "sing-what-they-have-in-the-book-first" mentality. We have IPM, so Fr. Weber's settings are a bit simple for her, and dare I say, to me, as well. So, we use some of yours, and she is loving the Marier, as well. We have, certainly, "upped our psalm game at St. Rita in New Orleans!"
