How to Set It Up with ThumbJam

1 - Open ThumbJam and select "Sound" in the top left corner.

3 - Select a sound. For this example, we'll choose "Trombone."   (Then tap the screen to make sure the Trombone sound is playing.)

2 - Then select "Change Instrument."

4 - Select "Prefs" in the lower right corner.

5 - When the list opens, choose "Options."

6 - Turn "Background Audio" on.   (Note: when you are finished with your ChordMaps2 session, you may want to turn this option off, or at least close ThumbJam. Leaving this option on with ThumbJam running in the background will use battery power.)

7 - Select "Preferences" and choose "MIDI Control."

8 - Scroll down to "Input Options" and make sure "In Channel Start" is set at 1. Then select "Done" at the top.

How to Set It Up

The basic steps, with any sound-generating app, are:

1 - Open the sound-generating app and choose a sound.

  2 - Make sure the app is on in the background. ("Background Audio" is on.)

      3 - Make sure the sound-generating app is responding to MIDI Channel 1.
