Congo Jr Master Playback (no master wing)

I'm not entirely sure what you mean!

On Congo Jr there are two main methods for controlling Masters:

• Set up a page of Direct Selects to be Masters
• Hold down the relevant Direct Select - this is now a Master Key - and use the wheel to raise and lower the Master.

Alternatively:

• Hit [Master] to open up the Master View tab
• Type # [Master] to select a Master
• Type # [@Level] to set it's level.

Or if you mean raising and lowering Masters automatically as you step through the sequence on the Main Playback, look up "Master Links", both on the forum and in the manual/online help.
