• To pilot WK4 with a master keyboard con-
nect the WK4 MIDI IN to the MIDI OUT of the

to simulate the WK4 keyboard, the master
keyboard must transmit MIDI on a channel

nel (refer to the chapters dedicated to MIDI).

It is possible to connect WK4 directly to a com-
puter via the COMPUTER port. It is not possible
to use the COMPUTER and PEDALBOARD ports
at the same time. The selection between these
two devices is made in «Edit General», «P.brd/
Cmptr» editor.
Macintosh and compatibles. Use a standard
serial cable DB8-DB8 available from computer
outlets. Program the sequencer to communicate
with WK4 at a velocity of 1 MHz.
PC-IBM and compatibles. Use a standard se-
rial cable DB8-DB9 or DB8-DB25 available from
computer outlets. Two communication velocities
are available for PC connection, PC1 and PC2.
