midi wifi between mac and Ipad ?

First thing is to make sure that in your audio+midi application on the mac that you have at least one session in the 'My Sessions' box. If not, use the '+' key and add one.

Select that session and tick 'enabled' in the Session window (right hand).

Once the session is there, you should see the iPad in the Directory panel with a green circle (assumes MidiBridge running and iPad and mac on same local network).

Click on the iPad and press Connect button.

To connect to the mac from MidiBridge make sure that on the mac 'Anyone' is set as 'Who may connect to me' and you will need to get the mac's IP address from the network preferences. Type that IP address into MidiBridge and it should connect.
