MIDI
MIDI is a communication protocol used to transmit and receive commands, messages and events that are then translated by the compatible
musical instrument into notes, events and commands. This protocol is used to connect a computer with dedicated programs to the XD9, to con-
trol other sound modules or keyboards directly from the XD9 and to connect the XD9 to an Accordion, a Sax or a MIDI guitar. Various books have
been written on the MIDI standard and some simple research via Internet or in any specialised library can help you better understand how it
works. Naturally, again on Internet, you can find sites that attempt to explain what MIDI is, free of charge. In any event a skilled musician will
not mix up the MIDI protocol with the Midi files (often called MIDI improperly): the first is indeed the starting point for the second. The XD9
(thanks to the polyphony) offers 32 independent MIDI parts. Sixteen parts are dedicated to using the keyboard when playing live, with separate
parts for the Arranger and the lead. The other sixteen are reached using the MIDI In 1 input that exploits the tone generator of the XD9 as a
module in independent General MIDI standard. The same sixteen GM parts are used to reproduce the Midi files in Song Play and in the sequencer.
The XD9 parameters are used to control each MIDI part and channel of the 32 available. Remember not to use MIDI cables longer than 5 meters
(15 Feet) to avoid running into transmission errors.
The XD9 distinguishes the programming of the parts between those in General MIDI and those dedicated to the single sections of the XD9. The
General MIDI settings are called up from the main page of the display using F1 GM and the MIDI settings of the keyboard are called up from the
main page of the display using F6 MIDI.
USING THE XD9 AS A GENERAL MIDI MODULE
To reach the sixteen independent MIDI channels from the keyboard, you must use a Midi file loaded in Song Play, or you can exploit the MIDI In
1 input (GM). With regard to Song Play there is a dedicated menu (F1 GM Part) that is used to modify the parameters of each single part, which
has already been explained in the Song Play section (see relative section). With regard to the MIDI In 1 input (GM), the modification page of the
parameters for each single MIDI part is enabled using F1 GM from the main page of the display. The parameters modified using F1 GM cannot
be saved, on the contrary to what occurs with the same parameters in Song Play.
MODIFYING A SINGLE GM PART
From the main page, press F1 GM Part to call up the page dedicated to the parameters of a single GM part. The Part is shown in the middle of
the display, the parameters (that can be modified) are assigned to the function push buttons. Right underneath is the voice assigned to the Part
and the effect used. The bottom part of the display is dedicated to monitoring the activities of the sixteen Parts on the MIDI In 1 (GM) input, and
can be useful when searching for the Part to be modified.
To move around between the single Parts use the PAGE +/- push buttons.
The parameters that can be modified must be selected using the dedicated function push button before the value can be modified.
Timbre: Each track can use a voice taken from the Voices and User Voices. To modify the voice assigned follow the normal procedure using the
VOICES, USER VOICES, PAGE +/- push buttons and the function push buttons.
Modulation effect: For each single track you can choose the modulation effect to be applied to the voice between Chorus, Distorsor and Delay,
