This is a web editor for the Valeton GP5. You have to use Chrome or another browser with Bluetooth Web enabled (for iphone you can use BLUEFY), and a desktop or phone with bluetooth.

You can use the keyboard to control some functions:

• On/off effects: 0 to 9 ( you can use also Q W E R T Y U I O P with MVAVE Chocolate in Custom keyboard mode)
• Tap tempo: space
• Previous and next patches: pgUp, pgDown

You can save the changes you make on the patch but it's only to the same patch you working on it. This is to prevent problems with the keybindings of tap tempo and effects.
