I hope that in the next update, please include global and drum buttons so that it will be easier to set up on the GP200... the global button is very important to me...

Hi, I'm from Bangladesh. I have some observations to highlight. This is a very good app, it would be better if it were added something more, such as the control option in the live interface. It would be more amazing if it were added with global eq, expression pedal, expression option and drums and looper. And I hope the next update will include these things. Best wishes.

The Valeton GP‑2xx app makes controlling the device effortless. Its clean interface lets you drag, drop, and edit effects in real time, manage amps, IRs, and global settings, and even assign modules to CTRL buttons with a tap. Fast, intuitive, and comprehensive, it turns the hardware into a joy to use. This is a game changer on making changes to my Valeton GP-200 JR.
