MIDI
Your instrument has a universal interface system between musical instruments called MIDI (Musical
Intrsument Digital Interface).
IMPORTANT
The information that follows does not concern a particular instrument or device but illustrates the
possibilities that the Midi system makes available to individual manufacturers.
To find out which of these functions have been activated on your instrument, please refer to the
instruction manual by reading the section on MIDI on your instrument.
What the Midi is for
This interface system allows several Midi musical instruments (even if they are made by different
manufacturers) to communicate with each other, also allowing the reception or transmission of
control or synchronisation signals to other Midi devices such as Sequencers, Electronic Drums,
Expanders, etc.
In the simplest case, it is possible to connect another synthesizer or expander (which takes on the
function of slave) to a synthesizer (which is defined as Master).
In this case, all notes pressed on the Master keyboard will also be played in sync on the Slave
keyboard.
It is also possible to change presets or transmit dynamics signals, pitch benders, etc.
A more complex type of connection is to create a chain of instruments or devices controlled by a
Master unit.
We can connect, for example, an electronic drum kit (which becomes the main unit or "Master" of
the system) to a sequencer and several musical instruments or expanders (which become peripheral
units or "Slaves" of the main unit).
In this case, the electronic drum set becomes the control unit for the whole system and starts the
sequencer in sync with the rhythm part, while the sequencer drives the rest of the peripheral
devices, assigning to each one the musical part previously recorded and managing the various preset
changes necessary for each individual unit.
