This is my entry. A bit late, but deadline is on Tuesday. So, not too late.
I played "Contrabourdon" by Vidas Pinkevicius.
I used Subbasa 32' and Principalbass 16' for pedals. For manual Violon 8' and Hemshorn 8' with closed Swell. And the most important task was not to forget to open it after playing 😊
