# Frequency Spectrum Layout

## Show +- freq bin size (coarse FFT error bar)

Freq. bin size gives error range for FFT without interpolation...

The various methods of interpolation can usually get the frequency to within much better than the frequency bin size for well defined clear peaks.

You can choose between the interpolation methods from Frequency Spectrum Peaks Pitch Detection (Ctrl + 68)

## Amplitudes

Use the raw amplitudes as volumes...

An increase of about 3 decibels corresponds (almost eactly) to a doubling of amplitude. So if you use amplitudes as the volumes, then the volumes will vary much more than they do if you use decibels.

Humans hear volume levels logarithmically - so assuming that the midi velocities correspond to perceived volumes, then you should use decibels to get the same volumes out as in.

However, synths vary a fair amount in how they interpret dynamic ranges.

If for some reason the midi device is using amplitudes instead of decibels to interpret the midi velocities, then you may want to use amplitudes. For instance if it has an option to select a linear midi velocity to amplitude mapping, and you are using that option then you may want to use amplitudes here as well.

## Decibels

Use decibels - corresponding to perceived volume - for the volumes...

This is the more usual situation. A doubling of amplitude corresponds almost exactly to an increase in volume by 3 decibels.

If you use decibels as the volumes, then the volumes will vary much less than they do if you use amplitudes.

Humans hear volume levels logarithmically - so assuming that the midi velocities correspond to perceived volumes, then you should use decibels to get the same volumes out as in.

So this is normally the best choice.

## Midi 127 is

Preset is 80. You can set this HIGHER to DECREASE the dynamic range...

This sets how many decibels 127 should be treated as. If a note is at its maximum amplitude, then it will be treated as midi velocity 127. The volume for a quieter note is found by working out how much quieter it is than the loudest possible note, and then subtracting the difference in decibels converted to midi note values.

So - if you set this large, then it means there are many decibels between the loudest and the quietest notes - so volumes have to be very quiet before they count as less than midi velocity 1, so the midi dynamic range is less for the same range in decibels.

If you set it low then notes that are still quite loud will come in below midi velocity 1 so many notes will get cut off as too quiet to sound.

## Scale Notation...

Set the notation such as cents, ratios etc used for display of all scale values...

Also has various options to configure how other numbers (volumes etc) are displayed in Tune Smithy.

## Ratios Options...

Options for display of ratios - factorise, lattice notation, etc.

## Calculator...

Use this for calculations - with special options useful for scales work

## Parts...

Set which instruments play in the Tune Smithy parts, and the volumes for parts etc...

You can set up any part with an instrument, volume, controllers and other parameters here. You can also set a different tuning for each part too using the Scales for Parts window.

This part then can be used in many places in Tune Smithy using the part number, and is the equivalent of a Midi Out channel in FTS. You can't use Midi channels directly as the notes for a single part often have to be relayed to many different channels for retuning purposes.

## Kbd...

Sustain pedal, modulation wheel, what to show on the keyboard, more options

## 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.
