A demo of the Principal chorus crescendo.
Pedal coupled to HW from start (no pedal stops on yet); Starting with the 16; then 8' added, then 4', then 2-2/3', then 2', then 1-3/5', then Mixture, then Cymbal, then Pedal flue stops added (also 32') then with Faghott 16' in manual, then eventually the Posaun 16' added, and after the first ending, a second ending with the labial Cornett added. The actual organ's plenum is still larger, since no Trumpet 8' or Oberwerk stops were used/added here.
