3.4 Connecting and switching on the accessories

You can connect accessories (for example, a MIDI device) to the organ.

1. Switch off the organ and the accessory.

2. Connect the accessory to the organ.

3. Switch the accessory on.

4. Switch the organ on.

3.5 External connections

The external connections are on the left under the console.

 MIDI IN: This is an input for receiving MIDI codes from other devices.
 MIDI MOD.: This is a programmable MIDI output for connecting a

module or expander, for example.

 MIDI SEQ.: This is a non-programmable MIDI output for connecting a

sequencer or PC (with the optional Johannus Intonat program), for
example.

 AUX IN: This is a (stereo) input for playing the sound of an external

device through the amplifiers of the organ. For example, an expander
that is connected to the organ through the MIDI MOD. can be played
through the instrument's loudspeakers.

Follow the instructions provided in the documentation for the
accessory.

PHONES

The volume of the device that is connected through the AUX IN
cannot be adjusted with the general volume or the expression
pedals. However, this is possible if the volume setting of the
external device is controlled by means of MIDI codes through the
MIDI MOD. connection of the instrument.

12

 AUX OUT: This is an output for connecting an external (stereo) amplifier.
 EXT. REV.: This is an output for connecting Johannus external

acoustics. This is a system that imitates the spatial effect of a concert hall
or cathedral.

 PHONES: This connection for a (stereo) headphone is suited for a

headphone with an impedance of 30 Ω or higher (see headphone
specifications).

Do not use this output for other purposes.

When the headphone is used, the internal and/or external
loudspeakers of the organ are automatically switched off.

13

4OPERATION

4.1 Expression pedals

Expression pedals adjust the volumes of the different divisions, Great stops/
Pedal and Swell stops/(Choir) (Choir is only possible with an organ that has
three keyboards).

4.2 Acoustics

The acoustics rotary control produces a digital acoustic effect. This effect
provides a spatial reproduction of the organ sound that can be adjusted
smoothly.

 Press the switch on the rotary control in for a 2D echo (standard echo for

clearer and more transparent sound).

 Pull the switch on the rotary control out for a 3D echo (extra addition to

the echo for a fuller sound).

4.3 Intonations

The intonations are divided into a main group and a subgroup.
The main group consists of:

 Romantic (ROM)
 Symphonic (SYM)
 Baroque (BAR)

The subgroup consists of:

 Classic
 Solo (SOLO)
 Hymn (HYMN)
 Trio (TRIO)

1. Select a main group by pressing the ROM, SYM or BAR piston.

2. Then select a subgroup by pressing the SOLO, HYMN or TRIO piston.

If no subgroup is chosen, Classic is automatically selected.

14

4.4 Factory intonation

Saving the intonation settings

1. Connect a PC to the organ. Use the MIDI SEQ. output, see § 3.5.

2. Save the intonation settings on the PC using the intonation program from
Johannus.

Restoring the factory intonation

1. Switch the organ off.

2. Press pistons 1 and 8 in. Hold the pistons down.

3. Switch the organ on.

4. Wait until the lamp in the 0 piston lights.

5. Release pistons 1 and 8.

4.5 Stops

stop is active.
The stops are divided into three groups:

 Pedal stops: Select the stops controlled by the pedal organ.
 Great stops: Select the stops controlled by the great organ.
 Swell stops: Select the stops controlled by the swell organ.
 Choir: Select the stops controlled by the Choir stops.

4.6 Couplers



Manual coupler: Couples all of the keys for the swell stops to the great
stops. To activate the manual coupler, use the swell stop - great stop,
choir, great stop or swell stop - choir (only for an organ with three
keyboards).

 Pedal coupler: Couples all of the keys for the great stops or the swell

stops to the pedal. Use the great stops - pedal or swell stops - pedal to
activate the pedal coupler.

To save the intonation settings, you need the Johannus intonation
program.

The current intonation settings will be lost if the settings are not
saved on a PC.

15

 Manual Bass (MB): Couples one note from the great stops to the pedal.

Only the lowest note that is played on the great stops is coupled to the
pedal. Use the MB piston to activate the Manual Bass.

 Cantus Firmus (CF): Couples one note from the great stops to the swell

stops. Only the highest tone played on the swell stops will be coupled to
the great stops. Use the CF piston to activate the Cantus Firmus.

4.7 Accessories



Chorus (CH): Is a function for lightly detuning the organ stops to give it
a broader and livelier sound. Use the CH piston to activate the Chorus.

 Fix Accessories (FA): This is a function for fixing accessories. As long

as this piston is switched on, the couplers and tremulants can only be
swiched on and off manually.

 Reeds Off (RO): This is a function to switch all reeds off in one go. As

long as this piston is switched on, no reeds can be swiched on. When
this function is switched off, the reeds that were on are switched on
again. Use the RO piston to activate the Reeds Off function.

 General Crescendo pedal (CR) (option): This is a function for switching

the General Crescendo pedal on and off. See § 4.11.11.

4.8 Changing the registration

The 0-piston cancels registrations in two ways:

 A short press on the 0-piston: Only the last change is cancelled.
 A long press on the 0-piston: All registrations are cancelled.

6.2 MIDI specifications

This paragraph contains more details about the specifications in the MIDI
Implementation Chart.

Default basic channels (transmitted/recognized)

2-manual instrument (with standard keyboard layout):

 1: Great stops
 2: Swell stops
 3: Pedal stops
 12: Stops

3-manual instrument (with standard keyboard layout):

 1: Choir stops
 2: Great stops
 3: Swell stops
 4: Pedal stops
 12: Stops

Basic channel changes (transmitted)

Can be programmed with the MIDI program.

Control changes (transmitted)

/i

Controller 7 (07h) General volume, with volume values 40 (28h) -

127 (7Fh).

Controller 11 (0Bh) Expression pedals, with volume values 63 (3Fh) -

127 (7Fh).

Controller 6 (06h) Pitch, with pitch values 33 (21h) - 95 (5Fh).

Pitch value 64 (40h) = A = 440Hz.

The following applies to the pitch:

LSB 100(64h) 1(01h) and the MSB 101(65h) 0(00h).

Transposer, with transposer values 61 (3Dh) -
67 (43h).

Transposer value 64 (40h) = A = 440Hz.

The following applies to the transposer:

LSB 100(64h) 2(01h) and the MSB 101(65h) 0(00h).

29

Control changes (recognized)

/i

Program changes (transmitted/recognized)

Organ stops: This depends on the number of stops and the sequence of
stops.
MIDI stops (programmable): 1-128.

System exclusive messages (transmitted/recognized)

Each ‘sys ex’ (system exclusive) message largely looks the same. The first
7 bytes and the last byte are always the same. Only the value of the 8th byte
varies. This is the ‘sys ex message’ that Johannus generally uses: F0 00 4A
4F 48 41 53 XX F7 (hexadecimal).
Therefore, with the ‘sys ex messages’ described below, only the value of the
8th byte (XX) is given, and from which output it is transmitted.

All stops off

The ‘all stops off’ sys ex code is 7F. This sys ex code is transmitted through
the MIDI SEQ. output when the 0 piston is pressed for a long time.
When an ‘all stops off’ sys ex code is received, all stops on the instrument
are switched off.

Thumb piston values

When a piston is pressed, a sys ex code is transmitted with the value of the
piston that is pressed (for example PP = 00 P = 01) through the MIDI MOD.
output.
These sys ex codes are only important when the Johannus sound module
CSM 128 is connected to your instrument.

Other MIDI codes (transmitted)

Press the 0 piston to transmit the sys ex code, ‘all stops off’ and all volume
settings through the MIDI SEQ. output.

Controller 7 (07h) General volume, transposer 0 (00h) -

127 (7Fh).

Controller 11 (0Bh) Expression pedals, transposer 0 (00Fh) -

127 (7Fh).

30

Sys ex code stops (Program Changes)

When a MIDI stop is switched on and off,
besides the usual Program Change, an
extra Program Change code (preceded by
the sys ex code 3F) is transmitted through

the MIDI SEQ. output. This is to distiguish
between a ‘normal’ organ stop and a MIDI
stop before transmitting a module.
When a stop is switched on and off, the
following codes are transmitted:

/i

Organ stop: Through MIDI SEQ. : CB XX

MIDI stop: Through MIDI MOD. : CX XX

Through MIDI SEQ. : CB XX and 3F CX XX
