That was indeed what I meant. Benjamin, do you want to post the solution as the answer, or shall I? Then Rezaul can mark it as accepted answer.

The reason this code works when you use input (with str2double) is that you have a number.
The code you posted uses the handle to the spinner, meaning you're trying to use the entire object. That doesn't just contain your chosen value but also many other properties (like the position etc).
If you use app.PitchSpinner.Value instead, that will retrieve the actual value. If you use that, your code should work again.
For the next time: if you use the debugger, you can step through your code line by line and have a look at the variables you have in your workspace. If you store app.PitchSpinner in a separate variable, you will see (e.g. by using class(app.PitchSpinner)) that the class of your variable is an object, not a number.
