PILOTING WK2 WITH A MASTER KEYBOARD

Master keyboards are generally mute instruments (without sound generators) and require
external sound sources to produce sounds. The WK2 sound generator can operate as an
external slave sound source for a master keyboard.
The Master keyboard must transmit MIDI messages on the same MIDI channel as the WK2
Common channel.
All Bank Select (CC00) and Program Change (PC) messages normally used to select WK2
sounds and transmitted on the Common channel are interpreted as Performance Change,
Style Change, Song Style Change or Song Change messages.
If you want to pilot the WK2 as well as other instruments with the master keyboard, connect
the MIDI IN of the expander to the MIDI THRU of the WK2.
Selecting Styles via MIDI Common
To select a Style from the master keyboard, you must send two control change messages
relating to the Bank Select (CC00: value 32) and (CC32: value 0) followed by a Program
Change (PC) message with the values shown in the following table:

Controlling Styles via MIDI Common
The Style controls can be simulated by sending Control Change 80 or 81 messages to WK2
via the Common Channel with the values shown in the following table.
If the master keyboard has programmable buttons, it is possible to assign them some con-
trol messages and control all directly from the master.
