About the App

Burea is an iOS application which allows you to play Lars Palo's sampleset the Hammarbergs organ of the church in Bureå, Sweden, on up to three MIDI keyboards and a MIDI pedal connected to your iPad. Starting with version 3.3, the app can also be used on iPhone and iPod touch. An iPad 2 or iPhone 5 or better is needed. Burea is based on the Napo framework. Please read the Napo documentation and in particular the Napo user manual to learn about its features and limitations.

Burea makes use of the Bureå Church sampleset version beta 2. The app's Gallery view shows photos that are part of the sampleset package. The stop button images and the Console view background image are derived from one of these photos. Furthermore, Burea contains impulse response files of Fokke van Saane, see http://fokkie.home.xs4all.nl/IR.htm.

If you don't need three manuals but would still like to get a virtual pipe organ for your iPhone or iPod touch, then have a look at the BureaMini app, which offers you a subset (Huvudverk and Pedal) of the Bureå organ.

There is also a free app Burea3o with the mid three octaves of the Bureå organ.

About the Organ

According to Lars Palo's documentation, this organ was built in 1967 by Hammarbergs Orgelbyggeri AB. It is a three-manual (56 keys) instrument with 28 manual ranks and a pedal (30 keys) with eight stops. This is the stops specification:

Usage with a Launchpad

Starting with version 3.3, the app is able to control the lamps of a Novation Launchpad MK2, see the corresponding section in the Napo user manual, and includes a default configuration for this, which can be loaded via the action menu of the Settings view. A nice mapping of the stops to the Launchpad buttons is not easy to find and certainly a matter of taste. In the defaults, we decided for the following allocation:

In accordance with the Console view, the left top is the Huvudverk, the left bottom the Pedal, the right top the Bröstverk, and the right bottom the Svällverk. Basically, white buttons represent principals and flutes, red is for reeds, yellow for mixtures and similar stops, and green for couplers. On behalf of an easier assignment, we put the couplers below the stops of the respective division (other than at the Console view or the real console).
