Accessing Track Settings

To access the Track Settings window, touch the settings button.

To move between panels and access all the different functions, touch the left or rightmost dots at the bottom of the window, or swipe the black window left or right.

(The Track Settings button may be pressed during playback or when playback is stopped. Some functions are able to operate in real time without disrupting playback; some require more processing so they need to halt the playback.)

 

Duplicate Track

The first Track function is 'duplicate track.' This function simply creates a new Track and copies the audio from the current Track, leaving the original unchanged. The Track volume, balance and edit points are also copied and inherited by the duplicate Track, within the current Loop. The original Track is automatically removed from the current Loop. The new Track is automatically added to the current Loop.

Only the part of the Track playable in the current Loop is duplicated; if the Track audio file is longer than the length of the current Loop, then only the first part of the Track will be duplicated.

When to use 'Duplicate Track' - this function is a simple way to produce stereo and echo effects. Duplicate the Track, make sure both are in the current Loop, then slightly alter the position of one compared to the other. This effect works better if you alter the balance and volume of each version (the original could be louder and more to the right, the duplicate could be quieter and to the left). Multiple duplications and edits allow you to produce more complex effects such as sound panning from left to right to left again.

 

New Track with Speed

The second Track function is 'New track with speed.' This function creates a new Track by taking the audio from the current Track and altering its speed according to the percentage chosen by the user. The original Track is unchanged. The Track volume, balance and edit points are also copied and inherited by the duplicate Track, within the current Loop.The original Track is automatically removed from the current Loop. The new Track is automatically added to the current Loop.

Only the part of the Track playable in the current Loop is used and slowed down/speeded up; if the new Track audio file is longer than the length of the current Loop, then only the first part of the Track will be used.

When to use 'New track with speed' - this function is a simple way to produce new sounds from existing recordings by altering their pitch. Slow down a Track to hear a lower sound, speed it up to make it higher pitched. It is also a simple way you can match the timing of Tracks that have differing bpms. (If you wish to alter the speed of Tracks without changing their pitch, export the audio in an email and use the more advanced functions of programs such as Garageband.) To halve the speed choose 50 percent. To double the speed choose 200 percent.

 

New Track with Amplification

The third Track function is 'New track with amplification.' This function creates a new Track by taking the audio from the current Track and altering its volume according to the percentage chosen by the user. The original Track is unchanged. The Track volume, balance and edit points are also copied and inherited by the duplicate Track, within the current Loop.The original Track is automatically removed from the current Loop. The new Track is automatically added to the current Loop.

Only the part of the Track playable in the current Loop is used and amplified; if the new Track audio file is longer than the length of the current Loop, then only the first part of the Track will be used.

When to use 'New track with amplification' - this function enables you to adjust very quiet recordings or very loud recordings that cannot be effectively adjusted using the Track volume. It is important to get the amplification level of Tracks right - too loud and you will hear distortion or strange "popping noises." Too quiet and you will not hear them above the other Tracks. To halve the volume, choose 50 percent. To double the volume choose 200 percent.

 

New Track with Low Pass Filter

The fourth Track function is 'New track with low pass filter.' This function creates a new Track by taking the audio from the current Track and applying a low pass filter to it with the cut off point as chosen by the user. This means that lower pitched sounds (below the cut off frequency) will be unchanged, but higher-pitched sounds will be reduced. The original Track is unchanged. The Track volume, balance and edit points are also copied and inherited by the duplicate Track, within the current Loop.The original Track is automatically removed from the current Loop. The new Track is automatically added to the current Loop.

Only the part of the Track playable in the current Loop is used and filtered; if the new Track audio file is longer than the length of the current Loop, then only the first part of the Track will be used.

When to use 'New track with low pass filter' - this function enables you to remove higher pitched sounds (e.g. background hiss) and alter the tone of the audio. Use a lower value for the cut off frequency and more of the higher pitched sounds will be removed. Combine this filter with the amplification function and you can boost lower frequencies. Combine this filter with the high pass filter and you have a band-pass filter. You can also use this filter to produce very realistic stereo effects - use the original track and alter the balance to the right, and use a filtered track with a bias on the left and you can mimic the effect of a stereo recording.

 

New Track with High Pass Filter

The fifth Track function is 'New track with high pass filter.' This function creates a new Track by taking the audio from the current Track and applying a high pass filter to it with the cut off point as chosen by the user. This means that higher pitched sounds (above the cut off frequency) will be unchanged, but lower-pitched sounds will be reduced. The original Track is unchanged. The Track volume, balance and edit points are also copied and inherited by the duplicate Track, within the current Loop.The original Track is automatically removed from the current Loop. The new Track is automatically added to the current Loop.

Only the part of the Track playable in the current Loop is used and filtered; if the new Track audio file is longer than the length of the current Loop, then only the first part of the Track will be used.

When to use 'New track with high pass filter' - this function enables you to remove lower pitched sounds (e.g. background hum) and alter the tone of the audio. Use a higher value for the cut off frequency and more of the lower pitched sounds will be removed. Combine this filter with the amplification function and you can boost higher frequencies. Combine this filter with the low pass filter and you have a band-pass filter. You can also use this filter to produce stereo effects - use the original track and alter the balance, and use a filtered track with a different balance and you can alter the apparent location of the audio.

 

Loop to Track

The sixth Track function is 'Loop to Track.' This function creates a new Track bymerging all the Tracks in the current Loop (including the current Track if it is in the current Loop) using the appropriate volumes, balances and edit points for each Track in the Loop. All original Tracks are unchanged, but all Tracks are removed from the current Loop, and the merged Track is added to the Loop.

This function performs the same effect as exporting the Loop in an email, except that it exports the current Loop as a new Track.

When to use 'Loop to Track' - this powerful function has two purposes. First it simply allows you to increase the speed of manipulating Tracks. If you are happy that your Loop will need no further editing and you would like to use it as the basis for other Loops in the future, then convert it into a Track. It is much quicker to load one Track instead of scrolling through ten. Second, this function allows you to have the functionality of copy and paste. Just create a new Loop, add the Track you would like to modify, alter its start and end points, then use 'Loop to Track' to create a new Track which contains only the audible parts of the original (i.e., a copy function). You can then add this Track to any other Loop (i.e. a paste function) or edit it further in a Loop and convert the result into another new Track. Using this approach you can edit any part of an audio recording, cutting, duplicating or shuffling its contents in any possible way. Because the original Tracks are never lost, you can also undo any edits by returning to the earlier files.

 

Duplicate Loop

The seventh Track function is 'Duplicate Loop.' This function simply creates a new Loop and copies all Track information from the current Loop. The original Loop and Tracks are unchanged.

When to use 'Duplicate Loop' - this function enables you to make an identical copy of your current Loop, leaving the original unchanged. This is useful when you wish to make variations of a Loop where only one or two Tracks may be different. This is commonly needed when building a larger composition from a series of Loops. Also, if you plan to use the 'Loop to Track' function then you may wish to preserve the Loop by duplicating it first.
