I was making a grid of buttons with TouchOSC yesterday, and wanted to set it up so that each button had a value assigned to it, and when someone pushes the button for the value to stick until they push the next button. So, if button 1 is pressed, it delivers a 1, then if button 5 is pressed it delivers a 5, for example - with only one value allowed to be generated in the button grid.
When I was looking through the options, there are pushbutton types that generate a value only when your finger is on the button, and then toggle types that you push on, then off.
The "problem" for using the toggle type for me, was that you could have multiple buttons depressed, whereas I needed the grid of buttons to only be able to deliver one output value - the last pressed.
I started fiddling around with some math patches and sample&holds, and realized I'd started recreating a part of smokris's VCR composition.
The solution is pretty simple - use the pushbuttons, and multiple each button value by the ID # that the button is supposed to have. Then, sum them all. Connect the output of the summing to the value input on a Sample & Hold. That's it! :-) I'm attaching a picture to show the setup.
