ios historical instrument reproduction

Picture
An iOS app was created with the aim of simulate a historical instrument.

The app is called "Claviorgue App" having the name of the original instrument that is recreating. Thus, this application is a virtual recreation of an already existing instrument. Located at the Barcelona Music Museum, it is older than 400 years old.

A Claviorgan is a combination of two keyboard instruments, in this case, a spinet (small harpsichord) and a small positive organ. Barcelona's instrument was constructed by Lorenz Hauslaib in Nuremberg around the year 1590 and is the only one made by this constructor that is completely restored and working.

Even though the original instrument is sounding, and the museum organises concerts using it, it is a 400 years old instrument, and the public who visit the museum is not able to play it. Therefore, the submitted app is an excellent opportunity to live the experience of playing this ancient instrument without damaging it. All the sounds used in the app were sampled from the original instrument by Pere Casulleras. Thus, the app sounds like the real instrument exposed in Barcelona. These recordings are used with Pere Casulleras agreement and also with the museum supervision.

Just after launching the app the first sound heard is the bellows, which provide the airflow to the organ. On the main screen the user can see a complete keyboard and a part of another at the bottom of the screen. In this position, the keyboards are linked playing both organ and spinet sounds at the same time. To play the instruments separately, the user has to slide the keyboard using the sides buttons (marked with an arrow). This linking technique is used because of the similarity of the technique used in the real instrument.

Like the original instrument, the keyboards have more than three octaves range (46 keys). Two octaves are visible in the screen, and the user can slide the keyboards horizontally to uncover the rest of the keys. The positive organ includes five stops: A Stopped wooden flute (4’), 15th in metal (2’), 22nd in metal (1’) and Reeds wooden/metal resonators (8’). The reeds stop is originally situated horizontally under the keyboard, pointing towards the organist. However, these pipes are not always visible since there is a removable wooden door to mellow the sound. In the app, the user can also choose to play with this door opened or closed.

Along with the already presented features, the app adds few features that are not possible to do with the original instrument. The user can change the volume of the instrument separately, remove the bellows sound or add reverb to the mix.
