  • Page 5: Description Of Stops

    Compound stops and hybrid stops are “variations” within these three families. The term “imitative” means that the organ stop imitates the sound of the corresponding orchestral instrument; for example, an imitative “Viola 8’” would be a stop voiced to sound like an orchestral viola. Section I MDS-30 LDS...
  • Page 6 In reed pipes, a metal tongue vibrates against an opening in the side of a metal tube called a shallot. The characteristic sounds of different reeds are produced through resonators of different shapes. The family of reeds subdivides as follows: Section I MDS-30 LDS...

  • Page 13 Off is also added. EXPRESSION PEDALS There are three expression pedals on the MDS-30 LDS. The one on the far right is the Crescendo pedal (see below). The pedal on the left expresses the Great and Pedal divisions, while the center expression pedal affects the Swell.
  • Page 14 Celestes are created by using two sounds, one tuned slightly sharp or flat of the other, creating a warm, undulating, “celestial” effect. Drawing the Viola Celeste II (8’) in the Swell Division or the Flute Celeste II (8’) in the Great division will both create beautiful celeste sounds. Section I MDS-30 LDS...
  • Page 15: Artistic Registration

  • Page 20: Transposer

    Transposer set down one-half or one whole step, then modulate up to the original key for the final stanza. The use of modulation with the aid of the Transposer can create a climactic effect for the final stanza of a hymn. Section III MDS-30 LDS...

    CAPTURE COMBINATION ACTION The MDS-30 LDS organ is equipped with Allen’s Quad Memory Capture Action, which offers the ultimate in registration control and convenience.

  • Page 22: Installation, Voicing, And Care Of The Organ

Factory assistance in planning the installation is also available and may, in fact, be sought by your representative, in order that optimal results may be achieved.
