| Shoulder Merging
Signal from one note often "bleeds" into neighboring notes, creating "shoulder" signals which may themselves be strong enough to be interpreted as played notes. Shoulder Merging attempts to remedy this problem by examining the shoulder signals of all notes with signals above the threshold and, if the shoulder signals are weaker than the cutoff value, merging them into the central note. For a more detailed explanation of this feature, see About the NoteProcessor.

| Merge Shoulders | When checked, Shoulder Merging is enabled. |
| Cutoff Percentage | Enter a value between 0 and 100. Shoulder signals will be merged with the center note signal when the shoulder signal exceeds this percentage of the center note signal. |

| Threshold
The threshold is the signal value above which the NoteProcessor interprets a note as being "on". The threshold can be either "fixed" (unchanging) or "floating". When the threshold is floating, its value changes so that it is always N-fold less than the last observed maximum note signal, where N is the fold offset from maximum. For a more information about the threshold, see About the NoteProcessor.

|
| Base Value | Enter a base value for the threshold. For a fixed threshold, this is the constant threshold value; for a floating threshold, this is the initial threshold value. |
| Floating | When checked, a floating threshold will be used. |
| Fold offset from Maximum | For a floating threshold, the last observed maximum note signal is divided by this factor to calculate a new threshold value. |

| Maximum Signal
The maximum signal is used to calculate velocities for MIDI note-on events. The maximum signal can be either fixed or floating. For a floating maximum signal, the maximum signal tracks the last observed maximum note signal, and the change rate determines how closely this tracking occurs (a value of 0 causes the "floating" maximum signal to become fixed; a value of 1.0 causes it to track the last observed maximum note signal exactly). For more information about the Maximum Signal and the change rate, see About the NoteProcessor.

| Base Value | For a fixed maximum signal, this is the the constant maximum signal. For a floating maximum signal, this this the initial maximum signal. |
| Floating | When checked, a floating maximum signal will be used. |
| Maximum Change Rate | Enter a value between 0 and 1 to determine how closely the floating maximum signal tracks the last observed maximum note signal. |
