EMC-48 and AMC-30 MIDI
AMC-30, 30 key anglo
concertina (amboyna veneers) MIDI
controller concertina, developed
by the Concertina Connection and Tethys, a Dutch computer development company.
EMC-48, 48 key english
Both the EMC-48 (English 48 key) and AMC-30 (Anglo-30 key) are a
combination of a
traditionally built concertina and a wireless MIDI controller.
The concertina plays, feels and looks like a 'normal' concertina. Both english
models have our brass double guided riveted action, "Wheatstone type"
keys (delrin core
with a domed metal sleeve), traditional brass end bolts, and 6
fold leather bellows. The
ends are French polished. Both models are available in
a variety of exclusive hardwood
veneers as well as "all black".
Although the bellows are not necessary with MIDI concertinas, we included them on these
to make the instrument play exactly like
a reeded concertina would. This is
true for bellows movement;
when playing a
note, the bellows also open and close,
on a reeded concertina, and
higher the pressure, the louder the tone.
In order to assure the correct bellows 'feel', we use the same 'all leather'
bellows as we do
on our other instruments, such as the Phoenix anglo and Geuns-Wakker models.
Both english and anglo models are reedless concertinas. The instrument
itself does not
produce any sound. Instead, the instruments transmit MIDI
information to a receiver
which can be connected to any MIDI compatible (sound)
source, such as a computer,
synthesizer module, keyboard, etc.. This sound
source determines the sound you'll hear.
For instance, if you select a flute or
piano sound, your concertina will sound like these
Both EMC-48 and AMC-30 models are wireless systems. The concertina is not
to the receiver. Because of this, the player is not limited in his/her
movement when, for
instance, playing on stage. The battery in the concertina can
be recharged through a
connector on the right side (bottom). This direct wire
connection can also be used
to send MIDI information to the receiver.
The instruments can generate data over two channels (layers) simultaneously.
you can combine two
different sounds at the same time. You can, of course, also use just
at a time.
On the left hand side the instrument has 2 micro switches to select the octave
(up-down). Both models can be set to 4 different octaves: bass(-2
octaves), baritone (-1)
treble (0) and piccolo (+1).
The receiver has several selection buttons and a led
display showing all necessary
information. Functions that are not changed
frequently (e.g. keyboard lay out etc.,) can
be changed on the receiver.
The concertina itself contains besides the MIDI electronics also a rechargeable
5 micro switches and 4 led's. The right hand side of the instrument
has 3 micro switches
the following functions:
* layer 1 selection
* layer 2 selection
The left hand side has 2 micro switches with the following
* octave up
* octave down
There are 4 led's on top of the right hand side (on both
models) that correspond with
the micro switches
The 4 led's on the right side of the concertina: (from top
* battery condition/recharge
* layer 1
* layer 2
The MIDI system includes 6 keyboard lay outs:
1 English treble concertina
2 English tenor
3 anglo Wheatstone/Lachenal
4 anglo Jeffries
5 anglo Irish
6 anglo Jeffries 2
7 free programmable lay out.
The free programmable lay out allows the player to develop/select his own
keyboard lay out.
Both the EMC-48 and AMC-30 models have been developed with the concertina
in mind. These instruments are still concertinas. The selection of MIDI

which only houses the contacts,
controls and transmitter, will not need to be
altered, just the electronics in the receiver. The
