@Veronica Leyva sounds good! If there is still such a conflict with the pre-mass Rosary, it might be worth considering doing your morning rehearsal in another space? Perhaps one that already has a keyboard there on the Church campus. The tremulant’s in general do make more of a theatrical sound, but using the 2 foot during this Easter season would probably work all right! Really, up to you just to experiment. And for rehearsal and performance group differentiation: totally up to you on how you’d like to handle it. I’ve always been a fan of letting people sing, but in my experience, it’s always under the pretext that there’s a large solid court group and then a few stragglers on the day. Obviously, it sounds like the inverse for you! So your strategy of not letting them sing unless they go to the rehearsal probably is best. Glad to hear that everything flowed well and that the congregation and Choir mesh!
