How to use the accelerometer in Garageband (iOS)

The accelerometer feature (available in firmware version 5.034) allows users to access a plethora of additional expression by mapping MIDI controller messages to an axis on the Jamstik+!

Example requirements:

- Jamstik+ (loaded with FW: 5.034+)

- Jamstik+ App

- GarageBand

- iOS Device

____________________

1) Turn on your Jamstik+ (wait for pulsing amber to indicate advertising connection)

2) Launch the Jamstik+ app

3) Connect to JS+ app

4) In the settings menu -> Accelerometer "ON"

5) Once the Accel is enabled select a controller message (1-16)

  • 0 = Accel off
