INSTALLATION
IMPORTANT
READ THIS DOCUMENT BEFORE INSTALLATION
Upon receiving this unit, remove any packing material inside the unit that may have been included to
prevent movement of components or wiring during shipping.
(For internal access, ensure the unit is disconnected from all power sources.)
Physical Installation
The CMK-2 can be mounted into a traditional organ console or set on a table. The American Guild of Organists’
standard dimensions state that the top of the lower manual’s keys must be 29.5” from the top of the pedals. If the
standard Classic MIDI Pedalboard is used, the table must be 32.5”
Figure 3a: Bracket Installation

13
Figure 3b: Bracket Goes Over Top of the Keyboard Mount
First, sit the plastic supports on the end of each keyboard (figure 3b) and fasten them in place with the #8 screws from
underneath (figure 3c). Then stack the keyboards by sliding the slots on the upper supports over the pins on the lower
supports. To slide the upper supports into place, first tilt the keyboard up about 30 degrees. At that angle, the pins on
the lower supports will slide through the slots on the upper supports.

Input 1: To this a swell shoe is connect for use as a normal expression pedal or as a crescendo pedal. Which it
is to be used as is configured using CMK Config software on a personal computer.
Figure 7 Wiring Schematic for Analog input
The CMK-2 has provision for up to four extra input functions on the circuit board. These inputs are reserved for future

Software Installation (Windows1users only)
Software installation instructions are described in the ‘CMK Configuration Software’ section of the manual.
Note: To use the software, the CMK-2 must be connected to a computer via MIDI. If a MIDI port is not available on
your computer, a commercial MIDI adapter for the game port, USB port, or parallel port may be used.

MIDI SPECIFICATION
MIDI (Music Instrument Digital Interface) is a communication system between computer-controlled music
instruments and describes all the actions of a musical performance. It was originally developed for music synthesizers
but, a few years ago, organ-builders began adding MIDI capabilities to pipe organs. However, as MIDI was not
designed for a complex musical instrument such as the organ, its standards are subject to organ-builders preferences.
MIDI is composed of three components which are the language (protocol), hardware (MIDI connector), and
distribution format (MIDI file) [1]. The MIDI language is in binary format and is a uni-directional asynchronous
stream of bits at 31.25 Kbits per second with 10 bits transmitted per byte. The 10 bits per byte consist of a start bit, 8
data bits, and a stop bit. In the hardware domain, the MIDI 1.0 Specification (maintained by the MIDI Manufacturers
Association) recommends the 5-pin DIN 180° connector. The 5-pin DIN connector is standard and allows MIDI
equipment from differing manufacturers to be connected together. MIDI cables transmit information in a uni-
directional manner so connectors are designated as either input or output. MIDI files are the standard distribution
format. They capture all the details of MIDI onto a hardcopy medium. MIDI files are similar to the MIDI language
except that they add a time-stamp for each event so that MIDI equipment can replicate the timing required to generate
accurate performances. [1] MIDI Message information can be found at www.midi.org.
Ahlborn [2]:
The Ahlborn Archive modules allow additional pipe organ sounds to be played on an existing organ. There are four
separate Ahlborn Archive modules of 20 different stops each over three separate divisions. For more information on
Ahlborn Archive modules, please visit: http://www.ahlbornorgans.com/archive. The messages for controlling Ahlborn
Archive modules can be found in Appendix D. The stop list for each module is shown below.

HAUPTWERKTM [4]
Hauptwerk 2 (German for ‘Great Organ’) is a computer simulation of a pipe organ. It produces a realistic organ sound
by use of a ‘virtual sampler’ technique. Traditionally, synthesizers used a small number of samples by recording keys
at intervals across the keyboard. In order to simulate all the keys, the samples were time-stretched. Hauptwerk 2uses
a 3 to 10 second sample of every pipe in the organ. To accommodate the intensive requirement for memory, a high-
speed personal computer must be used. With current technology, thousands of individual sample sounds can be stored
and recalled when a key is pressed. Thus, the software is able to capture many different and customizable organ
configurations and sounds which can be loaded via ‘.organ’ files. The ‘.organ’ file contains information regarding
number of stops, pistons, and keyboards in addition to other organ-related details.
The CMK-2 provides an interface for volume controls, expression controls, and pistons. MIDI messages will then be
sent through the MIDI out port to the personal computer where Hauptwerk software will translate the MIDI message
commands into actions on the organ. A table listing the types of messages sent for the individual functions is shown
below.
