The GuitarJack Stage Control app allows you to use Sonoma Wire Works' GuitarJack Stage hardware interface to control any third-party app with MIDI input (e.g. amp simulators, effects processors, recording apps). Use the GuitarJack Stage Control app to set the MIDI channel and map MIDI parameters for AmpliTube, Bias FX, Jam Up, Jam Up Pro, and other third party apps. Sonoma's FourTrack, StudioTrack, GuitarTone apps include the ability to to map MIDI parameters for GuitarJack Stage, so they do not require the use of this GuitarJack Stage Control app.

Before setting up, it's best to make sure that there are no other audio/MIDI applications running on your iOS device, as there is always the possibility of these apps interfering with each other.

To force other apps to close, press the Home button two times quickly. You'll see small previews of your recently used apps.
Swipe left to find the app you want to close.
Swipe up on the app's preview to close it.

To get started, launch a third party app with MIDI input,
then launch GuitarJack Stage Control, then switch back to the third party app.

See instructions for using each app in the Sonoma Wire Works forum and GuitarJack Stage Control online guide.

Unstable and not configurable to be able to use when other midi ie. bluetooth) devices are connected... frustrating that I really can’t use GuitarJack Stage like I want to.
