The organ is completely enclosed, with doors that can be opened to adjust the dynamic level, and the quiet blower is also inside. The retractable keyboard has 54 notes, C-f3, and can be slid to the left for antique pitch of A-415 and a dividing point of c1/c#1, or to the right for A-440, dividing at b0/c1. The two 8' registers greatly increases the dynamic, timbral, and textural flexibility so important for sensitive continuo use.
