WHAT IS MIDI?
MIDI is the abbreviation for “Musical Instrument Digital Interface”, a standard interface used
for communication between electronic musical instruments and computers.
This chapter discusses some of the more common MIDI applications for the WK2 on a
general basis.
WK2 is equipped with a standard MIDI interface consisting of a MIDI IN, MIDI OUT and
MIDI THRU ports.
To use WK2 as a stand alone instrument, it is not necessary to connect the MIDI ports.
With MIDI it is possible to:
• use WK2 to pilot another musical instrument;
• connect WK2 to an external sequencer (computer) to programme Songs and Styles;
• control WK2 with a master keyboard or other controlling device (guitar controller, wind
controller, drum pads...).
THE COMPUTER PORT
The COMPUTER port allows two-way communication between the instrument and a com-
puter without the need of a MIDI interface. The communication takes place via a single
serial cable.
When the COMPUTER port is in use, the MIDI ports are disabled.
If you have a computer capable of directing MIDI data to the serial port (specified as RS232
in IBM PCs and compatibles, MODEM in Apple Macintosh computers), you can substitute
the two MIDI cables with the single serial cable.
The connection via the COMPUTER port allows the control of 16 MIDI channels, as for the
standard MIDI interface.
Tracks and MIDI channels
Regardless of the current operating mode, WK2 can receive MIDI data on 16 simultaneous
MIDI channels. In transmission, WK2 can send MIDI data on 16 MIDI channels only in
Song mode.
You can assign any MIDI channel (from 1…16) to each track. A track can also be excluded
from MIDI by assigning the “Off” status.
In Song mode, the factory set MIDI configuration of the associated Performance is the
following:
Song track MIDI channel
1...16 1...16
In Style/RealTime and Song Style modes, the MIDI configuration of the ROM Perform-
ances is the following:
