Midi Numeration; Principal Midi Applications; Piloting An Expander (Or Other Keyboard) With Wk2 - GEM WK2 Owner's Manual

Note: a correct setting of the Common and Chord channel is essential to ensure full com-
patibility with a MIDI accordion ( see also " Piloting WK2 with a MIDI Accordion" on page 69).

MIDI NUMERATION

The numeration of MIDI data usually adopts the system 0-127. Some instruments adopt
the system 1-128. When you use devices that adopt a different numeric system, you must
remember to apply the appropriate conversion between one system and the other.

Principal MIDI applications

PILOTING AN EXPANDER (OR OTHER KEYBOARD) WITH WK2

If you want to pilot another keyboard or expander using WK2 as the Master
controlling device, carry out the connection as described below.
• Connect the WK2 MIDI OUT port to the expander's MIDI IN port.
Set WK2 to operate in Real time mode in order to be able to play at least
three sounds at the same time (Upper 1, Upper 2 and Lower keyboard sec-
tions). In Song mode, only one track is made available for real time use.
With this setup, the MIDI messages generated by the WK2 keyboard travel
from the WK2 MIDI OUT port to the expander's MIDI IN port. If you remem-
bered to match the MIDI channels of both devices, you will hear sounds from both devices.
If you want to listen to the expander's sounds only and exclude the WK2 sounds, you can
either regulate the WK2 track volumes to zero level, or you can set the WK2 tracks for
"Local off" operation (in «MIDI/GENERAL»).
If you save a Performance with all the track volume levels set to zero, you will be able to
listen to the expander sounds only.
By using the Local On/Off parameter and setting the keyboard tracks to "Off" (using buttons
F7, F8 and F9), the keyboard is disconnected from the internal sound generator, but the
keyboard messages are still transmitted via the MIDI OUT, allowing you to hear the ex-
pander sounds only.
Preparation
1. Connect the WK2 MIDI OUT to the expander's MIDI IN.
2. Select a Performance then the track you wish to program
NB. Program the track as required, assigning sounds, setting volumes and pan, effects,
etc.
3. Move the display arrowhead next to the MIDI/GENERAL menu function, then press the PAGE
button as many times as necessary until the display shows the "MidiENT" page.
The MIDI channels of the WK2 sections must match those of the expander. (Alterna-
tively, consult the expander's owner's manual to programme the expander's sections to
match those of the WK2).
