Bringing the unified ranks online.
THIS PAGE IS STILL UNDER CONSTRUCTION
All four unified ranks are now online. These ranks represent the four basic tone families of all organs that use real pipes, or are designed to be imitative of pipe organs: String (viola), Flute (tibia), Reed (brass), and Diapason (principle). Each of these can be played from most or all of the five claviers at various pitch levels. There are a total of 69 unified stops on the instrument, approximately one-third of the total stops not counting percussion and special effects. This is the primary reason these were brought back online first: a lot of tonal resources for the minimum amount of effort. The cabling for these is also simpler than for the other ranks.
Sound clips
These clips are based on the arpeggio format used in the online Encyclopedia of Organ Stops. More interesting clips will be available as time allows.
Those of you with even a moderately good ear will be able to tell that the tuning is not yet perfect, though most of it is close. Also, the amplitudes still need adjusting - there are some obvious problems in this regard. Also, there are still a few missing notes that we have yet to debug and repair.
Diapason arpeggio from C0 (33 Hz) to G7 (6272 Hz).
Viola arpeggio from C0 (33 Hz) to G7 (6272 Hz)
Tuba arpeggio from C0 (33 Hz) to C7 (4186 Hz) The highest stop on the unified Tuba rank is 4', thus there are no notes above C7 in this rank.
Tibia arpeggio from C0 (33 Hz) to G7 (6272 Hz).
For easier comparison of tone, this file has a C-major chord played first on the Tibia, then on the Diapason, third on the Viola, and finally on the Tuba. The Tibia is the "smoothest" or "mellowest" (it has fewer harmonics than the others), whereas the Tuba is the "brightest" (it has a lot of the higher harmonics present).
