Overview
Welcome to Tempo 2, the metronome app for advanced users. Because the usage of some of
the more complex features may not be immediately apparent, we recommend that you go
through this entire manual.
Tempo 2 works in both portrait and landscape orientations. For the most part, the app
works the same way in both modes. This document uses the illustrations from the landscape
mode only, except where the two modes work differently.
Tempo 2 has three main views: the Metronome, Setlist and Options views. A summary
of the Metronome View is shown below.
Additional options are available in modal panels, accessed by holding down on their
associated interface elements briefly. These are indicated in red above and in the app by an
icon at the top left corner.

Tempo
Tempo 2 supports a tempo range from 10 to 800 BPM (beats per minute). To set the tempo in
landscape mode, tap on the Tempo display, and without lifting your finger, drag left or right. To
make finer adjustments, move your finger further down the screen. This behavior is similar to
scrubbing music or video in the iPhone’s iPod app. A sandglass icon appears on the top right of
the Tempo display as you drag to indicate that the tempo is being modified. You can reverse
this behavior under Settings.
In portrait mode, start on the Tempo display (avoiding the adjustment buttons) and do a
rotational gesture, much like when using the click wheel on a classic iPod. Rotate clockwise to
increase the tempo, and anti‐clockwise to decrease it. It doesn’t matter where your finger goes
after the initial tap.
4
Adjustment Buttons
Tap on the arrow buttons at the bottom corners to increment or decrement the tempo. Hold
the buttons to adjust by steps of 10. Although the arrows look small, the hit areas for these
buttons are quite large, so you won’t miss them.
Tap Tempo
Tap in time on the Tempo display to set the tempo. The sandglass appears to indicate that the
app is actively listening for the next tap. When the sandglass is active, the next tap is
considered as part of the current ongoing calculation. Because the tempo can go as low as 10
BPM, the app needs to wait for 6 seconds before resetting the tap tempo calculation. Wait for
the sandglass to disappear before starting a new round of tapping.
Tempo Panel
Hold on the Tempo display without moving your finger to bring up the Tempo Panel. Use the
provided number pad to enter your desired tempo directly. The entered BPM is translated to
frequency in hertz and duration in milliseconds for your reference. Tap the “tick” button to
confirm the change and close the panel, or the “cross” button to close the panel without
applying the change.
Tempo Marking
The Italian tempo marking associated with the current tempo is displayed. Scroll through the
Tempo Marking display to set the tempo to the lowest value of the selected marking’s range.
Hold down on the button to bring up the Tempo Marking Panel. This panel lists all the available
markings for you to choose from. Note that BPM values for the markings are suggested; there
are no well‐defined values for these classical terms.

Time Signature
Time signature is described in Tempo 2 as Beats Per Measure and Subdivisions Per Beat, shown
on the Meter display at the bottom left of the screen. The large LEDs represent the beats, while
the row of smaller LEDs below them represent the subdivisions. Each LED flash in turn during
playback, with the smaller LEDs completing one cycle for each time a large LED flashes.
Defining time signature this way allows for greater flexibility and a more compact
presentation. For example, 3 beats per bar can denote 3/4, 3/8 or 9/8. The number of
subdivisions can then be set to lock down the actual signature desired. Using the same example,
setting 2 divisions per beat will yield 3/8, while 3 divisions will yield 9/8. 3 beats with 2 sub‐
beats can also mean 3/4 time in quavers.
There are two ways to set the time signature. In landscape, tap and drag sideways on
the top half of the Meter display to change the number of beats. Tap on the lower half to
change the number of subbeats. The position of the initial tap determines which numeral is set;
you can move your finger anywhere on the screen to give yourself more space before making
the desired adjustments. The time signature only changes when your finger is lifted. In portrait,
start on the left and right halves of the Meter display to edit beats and subdivisions respectively.
In landscape, the second way is via pinch gestures: pinch outwards with two fingers to
increment the number of beats or sub‐beats, and pinch inwards to decrement them. The
effective starting zones for the gestures are shown below; you can move your fingers out of
these zones once you have started the gestures.
6
In portrait, start in one of the zones shown to the left and do a rotational gesture.
Rotate clockwise to increase and anti‐clockwise to decrease the number of beats and
subdivisions. Where you start the gesture determines what will be edited; your finger can go
anywhere after the initial tap.
Configuring Patterns
Each LED can be configured to one of four states: Accent 1, Accent 2, Regular and Silent. With
the default sound settings, Accent 1 typically uses a tone with the highest pitch, and Regular
the lowest. Tap on each LED to cycle through the states. You can program a wide variety of
patterns this way. The pattern set for the subdivisions will recur on every beat. Note that the
first small LED for the subdivisions cannot be edited as it follows the main beats. Please see the
Options section on how to set individual sounds and volumes.
Presets
Five Preset buttons at the bottom of the screen gives you quick access to your favourite time
signatures and LED configurations. To save the current settings to one of these buttons, tap and
hold down on the Meter display. Once a Preset widget appears, drag and drop it onto the
desired preset. Note that Presets store only the number of beats and subdivisions, and the LED
states.
7
Bar Ticker
The Bar Ticker is found at the top right beneath the menu buttons. It keeps track of how many
measures have been played. The count value increases by one whenever a complete bar is
played. If the metronome is stopped, counting starts from the first beat when it is restarted.
To configure the Bar Ticker, tap and hold down on it briefly to bring up the Bar Ticker
Panel. Tap on the radio buttons to toggle each of the functions. Tap on a textfield to bring up a
number pad for editing.
You can choose to stop the metronome automatically when the bar total is reached; the
ticker will also reset to zero. Tap on the Bar Ticker anytime during normal usage to reset it to
zero. An infinity icon is shown instead if the ticker is deactivated.
The Bar Ticker functions are deactivated when the panel is brought up to prevent
disorienting automated changes to the metronome.
Auto Tempo Adjustment
The Bar Ticker also lets you configure the metronome to increase or decrease in tempo
automatically. This is also known as accelerando and ritardando in classical terms. Tap on the
button labeled “Increase” or “Decrease” to toggle between the two. If this feature is active, the
Bar Ticker will indicate it with two arrows pointing up or down.
8
Setlists
Metronome configurations can be stored as songs and organized into setlists. A song stores the
following: tempo, time signature, LED states, Bar Ticker settings and a title. Tempo 2 starts with
a default setlist that you can rename.
Tap on the Mode Toggler button to switch the Metronome View to Setlist Mode. The
Tempo Marking is replaced by the Setlist Control and the Preset buttons are replaced by the
Song Control. Both of these are scrollviews that scroll to the left and right. The Setlist Control
shows the currently active setlist. To add a new song to this setlist, tap the Add Song button.
The dialog that appears also lets you edit the song that is currently displayed on the
Song Control. Choosing the second option overwrites the song with the current metronome
settings with the option of renaming it. Another way to edit a saved song is to perform the
same action as you would when saving Presets. Hold and drag a Preset widget to the Song
Control. This method allows you to eschew the tedious dialog.
The Song Control is really made up of three portions. The central area is where you
scroll to other songs. Scrolling to another song does not immediately apply the Song’s settings.
This lets you inspect the songs in the list without affecting the metronome. To apply a song that
you have scrolled to, tap on the scrollable area like you would a button. The control flashes to
indicate that the song has been applied.
At the two ends are buttons to move to the next or last song. Using these buttons apply
the new song’s settings. These buttons can save you some time during live gigs. Refer to the
Options section for how you can set Tempo 2 to automatically advance through a setlist. Finally,
note that the two buttons may sometimes be obscured by a long song title; just remember that
they are always there.

Setlist View
Access the Setlist View with the first button on the menu bar. The Setlist View is a series of
table views with standard controls that you are familiar with. When first entered after the app
is launched, the currently selected setlist is shown. Tapping on an entry here will select that
song and apply its settings. Move up the hierarchy using the Setlists button to see your library
of setlists. Tapping on an entry here will select that setlist and move down the hierarchy to the
list of songs it contains. Note that this does not activate any song. Tap the Done button at any
time to return to the Metronome view.
Do a swipe on an entry in the Setlist View to delete it. For more editing options, tap on
the Edit button at the top left. At the top tier, you are presented with multi‐row deletion and
reordering controls (3 white bars). Each entry also has a disclosure button (blue arrow) for
editing the setlist name. At the lower tier, besides doing multi‐row deletion, you can clone
selected songs to other setlists or make duplicates in the same one. You may want to keep a
master list of all your songs and simply copy them out to ad hoc setlists.
When creating a new setlist, or editing an existing one, you can turn on the option to
loop it. A looped setlist moves back to the first song when the setlist is advanced manually or
automatically at the last song.
Note that editing of songs cannot be done within the Setlist View; it can only be done in
the Metronome View as described above. The reason is that editing a song will require
duplicating most of the Metronome View interface anyway.
iTunes File Sharing
You can save your setlists to your computer via iTunes File Sharing. Extract the file “setlist.plist”
via iTunes. Rename this file to keep multiple versions or share them with your friends. Make
sure a file is renamed to “setlist.plist” before usage in Tempo 2. Any existing file with the same
name will be overwritten.
Always shut down the app completely before moving files in and out. If Tempo 2 is
suspended while a file is loaded in, the file while be overwritten with whatever was previously
loaded in the app.
Note that the Tempo 2 “setlist.plist” file is not compatible with a Tempo file although
they share the same name.

Tuner
Tempo 2 provides reference tones for tuning your instrument. The Reference Tone button
provides quick access, playing a selected tone for a fixed duration when tapped. The
metronome is muted when a reference tone is played, but is not interrupted. Tapping the
button again while the tone is still playing stops it immediately. Hold down on the Tuner button
to bring up the Tuner Panel.
The Tuner Panel presents a keyboard to choose the desired note from. The selected
note is displayed at the top. Adjust the duration of the tone from 0.2 to 10 seconds using the
slider. Tap the button next to the slider to toggle to having the tone play for an unlimited
duration. You can play the tone stright from this panel by tapping on the tuner icon.
11
Volume
Tapping the Volume button turns audio on and off. To access more options, bring up the
Volume Panel by holding down on the button briefly.
Audio from Tempo 2 plays concurrently with music from your device’s iPod app. The
Volume Panel presents two separate sliders for controlling volume. The Main Volume slider
controls the overall volume of the device. Tempo Volume controls only the volume from Tempo
2. You can turn down the audio from the metronome in relation to your music if you find it too
loud.
The large volume icon on the panel also acts as a mute/unmute switch.
Refer to the Options section for how to set individual volumes for each metronome tick
type.
12
Options
The Options View contains four subviews, each accessible using the top menu buttons.
General Settings
Lock Tempo & Meter Controls ‐ Tempo and Meter controls are locked to prevent accidental
changes. Presets and Setlist songs are still selectable.
Orientation ‐ Switch between landscape and portrait. Auto‐rotation is not implemented due to
the large number of resources that are unloaded and loaded during switching, and the need for
the metronome playback to reset.
Disable Screen Auto‐Lock ‐ When switched on, your device’s Auto‐Lock setting is disabled; the
screen will never switch off when you use Tempo 2. This is for users who primarily use Tempo
2’s animations to keep time; it prevents having to always modify your device settings before
and after using Tempo 2.
Enable BG Audio ‐ The metronome continues to play when Tempo 2 is suspended in the
background.
Flash On First Beat ‐ The metronome gets a large flash on the first beat of each measure.
Automatically Advance Setlist ‐ In Setlist mode, songs configured with the Bar Ticker activated
will trigger a move to the next song in the list when the bar count is reached. If the “Stop when
reached” option is also selected, the metronome will stop playing. You can use this to program
count‐ins or complex songs with varying time signature or tempo.
Vibration ‐ Customize vibration for each tick type in Sounds Settings.
Bar Ticker Starts From 1 ‐ Enable this if you want the Bar Ticker to show the current bar instead
of completed bars.
Reverse Tempo Drag Gradient ‐ Fine adjustments are made at the top and course adjustments
made at the bottom instead.
Silence Applies to Whole Beat ‐ If a Beat is set to silence, all child subdivisions are also silenced.
UI Color ‐ Select a different UI color.
13
Sound Settings
Sounds Settings is where the metronome’s sounds are set. Choose a complete sound set or
customize each accent type. Vibration and volume controls are also available.
Sounds in the Pro set were specially crafted by Gavin Harrison for use in click tracks for
drummers. They achieve the best balance between audibility against live drums and comfort to
the ears. (Woodblock 2 is modified from Harrison’s Woodblock sound.)
