Xequence

Korg Gadget Demo Project

Download Korg Gadget Demo Project (zip, 635kB)

This is the Gadget project that contains the sound setup for the demo project (Alpha) included with Xequence.

To use this (slightly complicated, but it works!)

You should now be able to listen to the demo song. Note that the Gadget project uses a few synths that are In-App Purchases, so you might not hear all sounds unless you've previously bought those synths in Gadget.

Have fun!

App Development

seven systems develops apps for both major mobile platforms: iOS (Apple iPhone & iPad) and Android (effectively all other mobile devices).

For most apps, we use a hybrid approach: the same technology stack is used for both platforms, so we can create a consistent, high-quality experience that is almost identical on all devices, while still offering the look and feel the user associates with the respective platform.

This also means that we can spend less time (and you less money) on development, while still covering virtually all mobile devices in the hands of your users.

We would like to emphasize that we do not use any third-party libraries for rolling out our apps: the entire technology stack is ours and thus under our complete control.
