When the Over-pull Setup button is tapped, a new screen is presented where you can adjust four different parameters that affect how over-pull is calculated. Those four parameters are:

1. The highest note on the base bridge.

2. The highest note with wound strings.

3. The maximum over-pull that can be used on wound strings.

4. The maximum over-pull that can be used on plain strings.

The maximum over-pull that can be used on plain and wound strings allows you to specify more conservative safety limits for the wound strings, which may be more likely to break when over-stretched. And both of these limits allow you to take into account the physical condition of the strings to decide if you want to allow a very aggressive over-pull or a more conservative one. Here is a more complete description of safety limits.

The highest note with wound strings tells the software where to switch between using the wound string saftey limit just described and the plain string safety limit.

The highest note on the base bridge tells the software how much influence tuning one note has on another. In particular, two notes on the same bridge will interact with each other more than two notes that are on different bridges. If a piano is uniformly flat, this parameter does not really matter. It only matters when the piano starts off with some portions of the scale much further off pitch than others.

The two-fingered Z-swipe escape gesture can be used to exit from this screen.
