## Custom 2 or 3 Beat Fractal Rhythm

Customize how the rhythm is built up from L M S beats in Fibonacci pattern...

For details of this type of rhythm see the tool tip help for {{w32} and Fibonacci rhythm and tonescapes

This window lets you build the rhythm up using different patterns of L (Large), M (medium) and S (small) beats.

### How to get here

Bs | Tune Transformations - All | Fibonacci Rhythm | Custom 2 or 3 beat fractal rhythm or Ctrl + 34

### How to use this window

For the presets try the preset two or three beat rhythms.

To make your own rhythm choose one of the custom options. For instance for the two beat rhythms, choose Custom two beat.

Then enter any pattern of Ls and Ss in the replace L by text field. This will give the pattern of beats that will be played in a faster layer for every L beat in the next slower layer. Similarly enter any pattern of Ls and Ss for the replace S by field.

You will get some type of a rhythm whatever you enter. But if you want to make a fractal rhythm, you need to check that your pattern is fractal. If it is then you will normally see the words "found solution" below the Ratio of long to short beat. If curious to find out more about this see Fibonacci rhythm and tonescapes.

If you don't see "found solution" , try other combinations until you get a solution. You should make sure that the replace L by field has at least one S in it and the replace S by field has at least one L in it to get a solution.

In some cases you may find that the tune depends on what you set in the Initialise with text box. If you start with an S rather than an L at the slowest layer of the construction, then you still get essentially the same fractal rhythm - basically this difference corresponds to choosing a different starting point in the infinite fractal rhythm.

For three beat rhythms the process is similar, but you can also use Ms in the Replace L by and Replace S by fields, and you also need to enter a pattern for the replace M by field as well.

The method FTS uses to find a solution works for most three beat rhythms, but isn't guaranteed to always work. If it doesn't find a solution, it may mean that there is no solution, and indeed usually does. But as it isn't proved to always work, perhaps there might still be rare occasions where it is possible to find a fractal pattern by hand with some choice of the beat lengths which FTS misses.

If you want to follow this up see the section in Fibonacci rhythm and tonescapes about how FTS finds the solution: Fibonacci rhythm and tonescapes#How FTS finds the solution

## Play Fibonacci rhythm

Switch on the fibonacci rhythms for the notes

## Show all layers played

Shows all the layers here in the Custom beat window...

When switched on, you can still see just the first layer in the Fibonacci rhythm window

## replace L by

Enter Ls, Ms or Ss in any order for the beats to replace L by...

The Ms are only needed for the three beat rhythms

## replace S by

Enter Ls, Ms or Ss in any order for the beats to replace S by...

The Ms are only needed for the three beat rhythms

## replace M by

Enter Ls, Ms or Ss in any order for the beats to replace M by

## Ratio of long to short beat

Auto set to make all layers have same ratio if possible, so same rhythm...

The slower moving layers of construction of the tune have larger beats, which then are subdivided into smaller beats for the faster layers. This works out the rhythm so that all layers have the same ratio of long to short beat.

To hear this, make sure that Parts | Choose Parts by is set to By Layer so that each part plays a separate layer. Then all the parts will play the same rhythm, at varying speeds.

Whenever you change the beat patterns, this gets updated - however after you have entered the substitutions for the L, M and S, you can then go to this field and change the numbers if you don't care about making the rhythms the same in all the layers.

## Show beat length analysis...

Shows how the ratios were worked out..

It may be done analytically by solving an equation, or it may be done by recursively repeating the substitution many times to see what ratios turn out if you do that, then feeding that ratio back into the substitutions to check to see if it works.

Note that it doesn't try to be particularly elegantly presented, just to get the job done. Sometimes you may see the same equation appear up to six times for instance, then each root tested anew each time, as it was easiest to program it that way. One would never do it like that by hand but this was easier to program than the way one might set about it by hand.

For details of how it works, see the help.

## Ratio of middle to short beat

Auto set to make all layers have same ratio if possible, so same rhythm...

The slower moving layers of construction of the tune have larger beats, which then are subdivided into smaller beats for the faster layers. This works out the rhythm so that all layers have the same ratio of long to short beat.

To hear this, make sure that Parts | Choose Parts by is set to By Layer so that each part plays a separate layer. Then all the parts will play the same rhythm, at varying speeds.

Whenever you change the beat patterns, this gets updated - however after you have entered the substitutions for the L, M and S, you can then go to this field and change the numbers if you don't care about making the rhythms the same in all the layers.

## Ratio of middle to short beat

Shows the beats for first layer as they are played, long, middle or short...

See the Custom Rhythm window for an option to look at the beats in all the layers

## Ratio of middle to short beat

Shows the beats in all the layers as they are played

## Play Fibonacci tone scape

Switch on the Fibonacci tone scape type melody

## Pause

Pause playback, or continue play

## Play

It can play a retuned midi clip, chord progression, fractal tune or metronome

SHORTCUT FOR FRACTAL TUNES OR METRONOME

You can use Shift + click to fast forward...

Also Ctrl to fast forward even more. Shift multiplies the tempo by 10 and Ctrl multiplies it by 100, so the two together would play a fractal tune at for instance, 60,000 instead of 60 as the tempo. This is useful sometimes for fast forwarding through fractal tunes.

## Volume

Set master volume for FTS. Other controls also affect the volume...

Bs | Play control brings up the master volume control for Windows as a whole.

The volume is also affected by the volume for individual parts in the Parts (Ctrl + 9) window.

For the Wave shape player, go to the Wave Shape Player Audio Format (Ctrl + 188)

For CSound instruments, you can set the overall volume in the C Sound Save Opts (Ctrl + 168)

You can also vary the volume in Out | Options | More | Volume remapping, note on / off volumes etc. (Ctrl + 158) and if playing from Midi In there's another setting at In | Options | Keyboard Options | Touch. (Ctrl + 91)

## Fibonacci rhythm...

Constructs the tune from long middle and short beats in a Fibonacci pattern...

This is an unusual rhythm idea originally developed by David Canright. Instead of the beats repeating in a regular pattern, a fractal construction method is used.

Any short sections of the rhythm will eventually appear again later on, so there is a lot of structure and repetition of parts of the rhythm. But the rhythm as a whole never repeats exactly. So it has a feeling of repetition like an ordinary rhythm, but an elusive quality too because though larger and larger fragments of the rhythm repeat the whole thing never does so you never can find a point where as it were, the "bar" definitely ends.

Each layer also plays the same rhythm, at different speeds. So for instance the L + S beat pattern in the first layer (normally played on part 1) may correspond to a single L beat in the next (slower) layer, while the L beat in the first layer may correspond to a single S beat in the next layer. It continues like that through all the layers.

For details see Fibonacci rhythm and tonescapes

This option uses the main window seed but only the first few notes, as many as are needed for the pattern of short and long beats in the rhythm.

## Custom two beat

Make your own two beat rhythm...

Enter the beat pattern you want to use to replace each L, and S by. The rhythm is then made by starting with a single L beat, dividing it up as you have desired into L and S beats, then divide each of those into smaller beats again, and so on, repeating your substitutions many times.

## Custom three beat

Make your three two beat rhythm...

Enter the beat pattern you want to use to replace each L, M and S by. The rhythm is then made by starting with a single L beat, dividing it up as you have desired into L, M and S beats, then divide each of those into smaller beats again, and so on, repeating your substitutions many times.

## Help = F1

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

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

Reset, or Save settings for this window. RIGHT CLICK for all windows menu...

Shows the Organise windows window - which you can use to reset all the parameters for the current window.

You can also use it to save the settings for just this window, or open previously saved parameters for just this window.

Also has a drop list of all the windows and their shortcuts, and related options - some to do with the menu listing, and some to do with window resizing and minimising.

## Fractal Tunes Dialog Star

Tip of the day - Fractal Tunes category - right click for neighbouring windows...

Left click for a tip of the day in this category.

Right click to see a menu of neighbouring windows.

The neighbours are the ones you most often move to after this one or within a minute of this one, arranged by popularity.

So as you continue to use FTS, it will learn your habits, and the neighbouring windows listed here, should be the ones you most often visit after this one.

## Organise Windows = F2

Set the first beat to play in the topmost layer...

The other layers are filled in by expanding the topmost seed. Sometimes the choice of the topmost beat makes no difference to the other layers and sometimes it makes a big difference.

Example

L -> L S

S -> L

(long beat first)

The topmost seed won't affect the other layers as they will all expand to L

L -> S L

S -> L

The layers will expand to alternating Ls and Ss, and so the choice for the topmost beat will affect all the other layers.

## Initialise with

Used to initialise the first beat to play - but can get changed...

All the layers are set to play this beat - but then the beats for all the layers are worked out from the last layer downwards.
