Lissajous Pattern
Shows Lissajous figures as you play...

These patterns were originally made by a Frenchman Lissajous by shining light onto mirrors attached to tuning forks. They can also be shown using oscilloscopes.

The interesting thing about this pattern is that the same chord always has the same pattern whatever its pitch.

So for instance, all major chords with the same exact relative tuning have the same pattern, then there is another pattern for all minor chords, another for all diminished sevenths, and so on. Then there are separate patterns for each of the flavours of all those chords, for instance one for septimal minor chords, one for the ordinary just minor, and so on.

When you have a chord that uses small numbered pure ratios, for instance a chord in the harmonic series or other just intonation (pure ratio based) chords - the lines will join up after a few cycles around.

If the chord isn't quite pure, but close to just, then the lines continue for ever but they start off pretty much the same as the pure chords.

The pattern then would fill the entire area normally (if you set the time out high enough) so wouldn't be very interesting. So normally the lines are set to fade out if it continues too far to follow in the time available. This is configured in the Lissajous Colour and Line Options (Ctrl + 198)

Any that don't fade out can be finished if you give them enough time. The title will show that they need more time - use the Redraw with more time button to see the complete picture.

Some complex just intonation chords may fade out too, because Tune Smithy didn't follow the curve far enough to find the place where it joins up. The calculation continues ahead of the place it reaches with the drawing, so Tune Smithy can show many fairly complex just intonation chords without fading them out. But sometimes it just doesn't go far enough in the calculation to recognise them.

If the pattern fades out, and you know that it is in fact just intonation, and want to see the complete curve, increase the time out if necessary, and again, use the Redraw with more time button.

Though this window doesn't have an obvious menu, it does have one hidden away. Click on the icon at top left to bring up the menu with Close, Resize etc - and look down there and you will find some other options specific to this window - this is a simple way to keep some of the more often needed options ready to hand. You will find the redraw with more time option there, also one to print the window, and the options for the window

Help = F1
Click for help for this window. Or F1. Other opts: Shift, Alt, Ctrl + click...

F1 or click shows the help for the current window in your web browser.

Some windows may have no help yet in which case the help icon is shown crossed out with a red line.

Shift + F1 or Shift + Click brings up the tool tips extra help window (this window) to show any extra help for a tool tip.

You can tell if a tool tip has extra help if it ends ... like this one.

Ctrl + F1 or Ctrl + click takes you to the list of keyboard shortcuts for Tune Smithy.

Alt + F1 or Alt + click (alternatively Caps lock physically held down + F1 or Click) takes you to the on-line page at the robertinventor.com web site about the current main window task - which gives a short introduction to it for newbies to the program. If there is no on-line page specific to a task, takes you to the main tune smithy page on the web site.

Since the help for Tune Smithy is currently a bit out of date and needs to be redone completely for the new 3.0 release, then you may find the on-line page for some of the newer tasks particularly useful.

Organise Windows = F2
