Allow setting the initial value manually
Allow setting the initial value manually

Sometimes it's desirable to set the initial value to a predefined value (say, a encoder that controls both "volume" and "frequency", by switching between these functions, it's helpful if we can set the initial value to the current internal value.

I've been doing this by setting the min_val to -100, and then applying the offset to my current value, but I've figured this is more elegant.
I've tried to keep it compatible with how it was previously, but please correct me if this is not right.
