21 Viennese Horn - VelXF sus
Regular A0 > Perf. repetitions F0 > Portato D#4 > Crescendo (9) A#6
Playing repeated notes, the crescendo plays through the fifth repeat. The sixth repeat (and possibly the seventh) interrupts the crescendo. Continuing to play moves onto the final, loudest note.
The diminuendo of the same patch performs as expected.
