To set up your keyboard to be recognized by Playground Sessions, please follow the steps below.
CONFIGURE MIDI KEYBOARD
While the keyboard is connected to your device and powered on, launch Playground Sessions and click on Edit in the top menu, then click on Configure MIDI Keyboard from the dropdown menu.
In the next window, click on the dropdown menu and select the name of your keyboard as the Keyboard Model. If you don't see your keyboard as an option, but see the name of your cable, go ahead and select that instead. Then, click Next and finish the configuration.
