Connect MIDI equipment to your Android device

All G-Stomper apps, G-Stomper Studio, G-Stomper VA-Beast and G-Stomper Rhythm, come with support for MIDI over USB (host + peripheral) and MIDI over Bluetooth LE (host).

Depending on your device and Android version, some of these options might be not available (e.g. MIDI over Bluetooth is only available on Android 6 or higher).

Detailed instructions for the particular connection types are provided in the Online documentation or the Printable PDF.

USB MIDI Cables & Adapters

Depending on your device one of the following adapter cables is required:

USB Female to Micro USB Male OTG Cable Adapter for devices with Micro USB connector

USB Female to 30 Pin USB Male OTG Cable Adapter for Samsung tablets with 30 Pin USB connector

Most modern MIDI controllers/keyboards can be connected directly over USB using the USB adapter cables mentioned above.

Note: A good practice is to use self-powered MIDI controllers (which can be used with an external power supply) or controllers with a special low-power mode (like the Akai MPK225) to minimize the battery strain on your Android device.

Connect classic MIDI equipment to your device:

To connect Non-USB MIDI hardware equipped with a classic 5 Pin DIN connector, an USB class-compliant MIDI Interface is required.

Good alternatives for the ESI MidiMate II are the TIE MIDI 1i1o or the Roland UM-ONE mk2.

G-Stomper MIDI integration
