Application of MIDI

What is MIDI?

MIDI is the abbreviation for Musical Instruments Digital Interface. With MIDI, musical
instruments can be coupled to each other or to a computer. Thus, it is, e.g. possible to play
simultaneously both your instrument and a synthesizer or expander. The MIDI-standard is
partly based on hardware. In addition, it is a description of the way in which music and
sound are translated and in which communication takes place between devices equipped
with MIDI-functionality. The MIDI-codes which the Monarke instrument can transmit, tell
e.g. which key has been pressed.
Components relevant to MIDI:
! MIDI-connections (MIDI IN, MIDI THRU, MIDI OUT) on instruments without
programmable MIDI.
! MIDI-connections (MIDI IN, MIDI MOD, MIDI SEQ) on instruments with programmable
MIDI.
! MIDI-stops (or switches).
! A device (e.g. synthesizer) you wish to control via MIDI.
! Connection cables.
The MIDI-stops may be designed as (lighted) thumb pistons, or as stops.
Each MIDI-stop has a number. For example, the stop MIDI GREAT on a 2-manual
instrument has number 1 and on a 3-manual instrument, number 2. This number indicates
the channel through which the key information is transmitted when you play on the great.
The channel numbers going with a certain division are fixed on instruments with non-
programmable MIDI. On instruments with a programmable MIDI-function they can be
changed by the user (see at "Programmable MIDI").
MIDI has namely 16 channels through which information can be transmitted.
With the MIDI-stops, you determine from which keyboards you wish to transmit MIDI-
signals with key information to other devices.
If your instrument has no MIDI-stops, key information is always transmitted from (of) all the
keyboards.

How and what to connect?

Suppose, you wish to connect three expanders to a 2-manual instrument without
programmable MIDI. You want to play one from the great keyboard, the second from the
swell keyboard and the third from the pedal.
Follow this line of procedure:
1. Connect the expanders with the MIDI-cables (DIN-cables).
2. Switch on MIDI GREAT 1. The appropriate expander should be set in such a way that
it receives only data via channel 1.
3. Switch on MIDI SWELL 2. Pay attention to the setting of the corresponding expander.
4. Switch on MIDI PEDAL 3. Pay attention to the setting of the corresponding expander.
