About the App

MarcMoerd is an iOS application which allows you to play Ariaan Hoogendijk's sampleset of the Marcussen organ of the (former) St. Stefanuskerk in Moerdijk, Netherlands, on up to three MIDI keyboards and a MIDI pedal connected to your iPad (with exception of iPad 1). MarcMoerd 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.

For the app's GUI we have adopted the stops layout of the sampleset, which differs slightly from the layout at the real organ. Some stop names have been broken to two lines to improve readability on the iPad screen.

The above iTunes artwork image, as well as the app's icons, were created by retracing a Wikimedia Commons image by Bert Wisgerhof (license CC BY 3.0), which is also part of the images gallery of the app. The background pattern of the Console view was created by using a console photo at brabantorgel.nl (see below).

MarcMoerd 1.0 was featured by The Sound Test Room. Verdict: "superb", "built for professionals." You can find the video below in the Demo Videos section.

There is also a free app MarcMoerd3o with the mid three octaves of the Marcussen/Moerdijk organ.

About the Sampleset

The Marcussen sampleset was one of the first commercially available samplesets and does to this day wow by its sound and versatility. At marcussenhauptwerk.nl you can get versions for Hauptwerk and GrandOrgue and even a Soundfont version. Listen to the recordings at contrebombare.com made with this sampleset and Hauptwerk.

For the MarcMoerd app, we have processed the loops of the sample files with crossfading because Napo (in contrast to other software) does not crossfade while playing the files. Furthermore, we altered a few of the Pedal Mixtur files to get rid of 'click' artefacts.

About the Organ

Marcussen & Søn, a renowned Danish organ builder company, crafted this neo-baroque instrument for the St. Stefanuskerk in Moerdijk in 1964. When the church was closed in 2013, the organ was relocated to the St.-Joannis Baptistkerk in Klundert. There is a video at YouTube of the dismounting process, and at brabantorgel.nl you can see pictures of the organ at its old and at its new home.

The organ has three manuals (56 keys), a pedal (30 keys) and a total of 28 ranks, including some very nice reed ranks:

Huvudvaerk (C-g3)
Principal 8' Oktav 2'
Rørfløjte 8' Mixtur 2 Kor

Usage with a Launchpad

Starting with version 1.3, 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. For this app, it would have been unfavourable to put the buttons for the combination banks and combinations in the bottom two rows. Instead, they are in the right two columns, which allowed an allocation where the stop buttons are arranged similar to the portrait mode of the Console view:

In accordance with the Console view, the left top is the Huvudvaerk, the left bottom the Pedal, the right top the Brystvaerk, and the right bottom the Rygpositiv. Basically, white buttons represent principals and flutes, red is for reeds, yellow for mixtures and similar stops, orange for tremulants, and green for couplers.
