Tune your Tempo
Calculate a tempo that is in tune
Open the simple view.
Enter a key in step 1 and a mode in the step 2.
Just copy the result into your DAW.
Use the result to tune your drums
Example: Unison for the kick, the fifth for the snare and the fourth and sixth for the toms.
Enter a tempo in Expert view
Tune to the closest key be clicking the cent-button.
Calculate the Concert Pitch
Enter a tempo or frequency you want for your song.
Press alt and click the cent-button. ToneCalulator will provide you with the correct concert pitch and the Keynote.
ToneCalculator helps you bring your songs in tune. Finding the right tempo that fits best to your song.
When something swings below 20 Hertz we can’t hear the frequency but perceive it as rhythm. So the tempo is a frequency below our hearing range, but still a frequency that is either in tune or not.
A big part of music feeling natural is having every part of the arrangement and environment being in sync with the other elements surrounding it. So ToneCalculator also provides you with the correct (in sync) data for your Delays, LFOs, pre delay times of your reverb, attack and release times of compressors and other envelops.
Figure 1: General buttons
When ToneCalculator is started it shows up in Simple View (see Fig. 2). Here you can enter the key of your song in Step 1. Than enter the mode, which can be major or minor in Step 2.
If you are interested in a more sophisticated mode, you can pick a scale from the Scale-menue. If you don't find the scale that you are interested in, than go to Expert-view and select the Custom scale. Edit the scale and return to Simple-view.
ToneCalculator provides you with the Result on the right side of the window. In the table inside the Result-box you can find all tempi that are in the key you picked in step 1 and 2.
The lower list are the best frequencies to tune your percussion instruments to. Most harmonic is the octave (unison) followed by the fifth, fourth and so on.
Example: Tune your kick drum to Unison, the snare drum to Fifth and the toms to the Sixth and Seventh. Use the „multiplication“-buttons (see Fig.1) and try one octave lower of Unison for the kicks subbass frequency.
Figure 2: Simple View
You can start by entering a tempo or a frequency in the first box called Tempo (see Fig. 3-1). The tempo is measured in bpm (beats per minute).
The frequency below the tempo is the 8th octave of the tempo, meaning the tempo was doubled eight times and converted in hz (Hertz) which is equal to bps (beats per second).
Note: 60 bpm = 1 bps = 1 Hz (Hertz).
Once you entered a tempo you‘ll find the closest root note to the tempo in the „Root note“-box.
Below the tempo and its frequency is the „cent“-button. Tune the tempo to the root note by pressing the button and setting cent to 0. The indicator in the Tempo-box will turn to green, meaning the tempo is now in tune with the root note.
Tip: If you hold the alt-key and press the „cent“-button the concert pitch will be changed instead of the tempo. Use this function if you want to have an exact tempo, but keep in mind that you have to change the concert pitch in your DAW which is usually set to 440 Hz.
You can also click on the root note and ToneCalculator will provide you with the tempo, that is an octave of the picked root note. Use the multiplication buttons to jump to other octaves.

Figure 3-2: Expert View with table unfolded
Click on Duration to see the times of quarter notes, 8th notes, 16th notes and so on. The 2nd column shows dotted notes and the 3rd column shows triplets.
These times can be used for delays, reverbs (pre delay time), compressors and gates. Especially compressors are often not linked to the DAW’s tempo.
To find a good entry point for the pre delay time of your reverb enter your tempo and than use the 64th note (see Fig. 4) as your pre delay time.
Tip: By adding half of a millisecond or rounding the given value up to the next full number, the result may even sound a little bit more pleasing.
Switch from ms to hz to display the low frequencies. These are used for LFOs (low frequency oscillators) inside your favorite synthesizer.
Switch to Samples to show the duration of the notes in samples. Don't forget to adjust the SampleRate on the right to the SampleRate of your project.

Click on Scale to activate the scale matrix. Only the selected notes are displayed in the table on the right. You can choose between several presents by clicking on the selector underneath the table or the root note. You can also pick a different scale next to the play-button of the arpeggiator (see Fig. 5).
Figure 5: Scale-tab
The values shown in this tab give you the distances it takes for the sound to travel in musical times or certain note lengthes. The default value for the speed of sound is in air at room temperature (343.2 m/s).
Positioning your microphone in the given distance will result in a delay that is synced to the tempo of your song.
There are some room simulations with a variable room size. This is where distance-values also come in handy.
Figure 6: Distance-tab
This is a table of frequencies as they occur in nature and therefore in the overtones of instruments. In the last column “cent” the difference to the note in equal temperament is shown.
Note: In equal temperament the octave is devided in 1200 cent. So the difference between two neighbouring semi tones is 100 cent.
Important: You can only access the Natural-tab, when you are in Expert View.
Figure 7: Natural-tab
Here you can find a collection of different scales. Selecting a scale will affect the Simple and the Expert view and will change the output of the view's table.
You can select the scale also in Expert view under the table or the root note.
Here you can find a collection of frequencies, that can be an inspiration for your compositions. But be aware of a change in the concert pitch in order to get a specific frequency.
