Ctrl for iPad, automatically adds a float value to the end of the string sent out by slider or steppers.
For buttons, you can define float or integer values by leaving a space at the end of your OSC string and between each integer or float value you wish to transmit. CTRL for iPad will format the information entered into the box as the type you require.
<IP>:<Port>/trigger/intensity 1 2.5 hello
Would be seen as
/trigger/intensity 1 (int) 2.5 (float) hello (string).
To try this for yourself feel free to try the demo version for Ctrl for iPad with our protocol tester CommsKit.
