The Learning Metrics Dialog Box

The Learning Metrics dialog box keeps score on how you're doing in trying to learn the music. It also allows you to specify the way you do the learning. Also, it provides useful information, by monitoring the notes coming through, to tell you the key-signature(s) used by the piece. This allows you to set up performance panes in the KeyMusician Keyboard using those key-signatures, so you don't have to worry about the black keys (flats or sharps).

Here is a picture of the Learning Metrics dialog box:

Screen-shot of the "Learning Metrics" window.  On it, the "Sight-Reading" radio-button is set, as well as the "Audio-Help" and "Visual Help" check-boxes.  The "Input Key-Sigs" drop-box has "2. transpose equals two (two sharps) selected.
The top row (“MODE) lets you specify whether you're learning by seeing & matching the notes (Sight-Reading), or by hearing & matching the notes (Play-By-Ear). Only one of the two modes can be selected.

The current performance-pane's “MIDI Channel” must specify a channel in the “Channels” text-box of the Player/Recorder in order for any notes to be displayed, or known-of to be matched in playing by ear.

The “Options” row contains check-boxes allowing you to further-control the learning mode selected above.

The “Audio Help” check-box is only effective when “Sight-Reading” mode is selected, and the “Playback Device” in the Player/Recorder is set to “(none) – Display Notes Only”). With this control checked (selected), the notes displayed will also be played using the parameters of the Chords panel. If this control is not checked (not selected), only the notes you actually play are heard, and you do not hear the notes to be matched.

You can change the Chords panel instrument (and other parameters) to control the sound of the notes produced.

The “Audio Help” check-box has no effect when “Play-By-Ear” is selected, or when the Player/Recorder's “Playback Device” is something other than “(none) – Display Notes Only”.

The “Visual Help” check-box is used in the “Play-By-Ear” mode, causing it to also show the notes. If it is not checked (selected), no notes are displayed. It has no effect if “Sight-Reading” mode is selected (since the notes need to be displayed in that mode).

If the “Wait” check-box is checked (selected), playback of the piece you are learning will slow to almost stopped (with all notes left sounding) until you play the correct note. This is really helpful in learning to play a new piece by matching the notes. But you wouldn't want it set if you were improvising with the piece, since you don't necessarily play the displayed notes.

The “Time To Match” row shows your average time (as a decimal fraction of a second) it took you to match the notes. This statistic is less useful than the others, though still good information. It is possible for this value to nearly approach 0.0 as you become skilled at the piece, anticipating the notes to be played.

The next three rows each show two numeric values. The first (on the left) is the total number, and the second (on the right) is what percentage that number is of the total number of notes so far in the piece.

The “Matched-Notes” row is for the notes you matched. For this row, bigger numbers are better ( ☺ ).

The “Missed-Notes” row is for the notes you missed. A note is missed if it is displayed, but ends before you match it. On this row, smaller numbers are better ( ☺ ).

The “Wrong-Notes” row is for the wrong-notes you played. A wrong note is when you play a note, but it isn't the same as the note (or notes) displayed. On this row, smaller numbers are better ( ☺ ).

The “Input Key-Sig's” drop box contains a list of the key-signatures detected in the notes being displayed (coming from the player, for the selected MIDI channel).

They appear in the drop-box in the order they were detected.

You can watch this drop-box as the music plays. If a key-signature appears for a relatively short time, it is not useful to set up a performance panel in the KeyMusician Keyboard for it. On the other hand, if it remains displayed for a long period of time, it is one you want to set up a performance panel for.

The “Reset” button allows you to clear the statistics, to start accumulating new numbers. When you click (tab-to and activate) the “Play” button of the player (after either reaching the end of the piece, or clicking the player's “Stop” button), the statistics are cleared for you. Pausing & resuming the player does not clear the statistics.

The “Help” button activates your default browser to display the help information pertaining to the Learning Metrics dialog-box (what you are reading now).
