Midi; Using The Unit As A General Midi Module; Modifying A Single Gm Part - KETRON SD1 User Manual

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 therefore used to connect a computer with dedicated programs to the
SD1, to control other timbre modules or keyboards directly from the SD1 and to connect the SD1 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 to better under-
stand 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 SD1, 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 timbre generator of the
SD1 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 SD1 parameters are used to control each MIDI part and channel of the 32 available. Remember not to use MIDI cables longer than 15 meters
to avoid running into transmission errors.
The SD1 distinguishes the programming of the parts between those in General MIDI and those dedicated to the single sections of the SD1. 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 SD1 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 in the sequencer, 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 mod-
ification 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 of which (that can be modified) are assigned to the function push buttons. Right underneath is the timbre 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 to find 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.
TTimbre: Each track can use a timbre taken from the Voice, User Voice and RAM/Flash bank. To modify the timbre assigned follow the normal
procedure using the VOICES, RAM/FLASH, USER VOICE, 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 timbre between Chorus, Distorsor and Delay,
using the CURSOR +/- push buttons. The effect entity can be programmed using F3 Chorus/Distorsor/Delay.
F1 Volume:
F2 Reverb:
F3 Chorus/Distorsor/Delay:
This modifies the volume of the whole track. The value can be changed using the VALUE +/- push buttons which,
if pressed together at the same time, reset the value.
his modifies the Reverb entity applied to the track. The value can be changed using the VALUE +/- push but-
tons which, if pressed together at the same time, reset the value.
This modifies the entity of the modulation effect chosen between Chorus, Distorsor and Delay assigned to the
track using the CURSOR +/- push buttons. The value can be changed using the VALUE +/- push buttons which,
if pressed together at the same time, reset the value. The display shows the type of effect chosen next to F3
and also below the timbre.
