The Pattern panel is where the drum patterns are created and is composed of three principal areas:
  • Toolbar/Menu Bar on top that remains constant for all panels.
  • Tracks on the right contain Steps
  • Pattern Modifiers on the left menu to draw, copy and move steps (Edit Mode), edit their parameters with Volume, Pan, Pitch and Offset (Step Modes), change signatures, and add/change tracks to create custom drum kits.
  • Track Customization Kit to create custom drum kits and connect the iPad server.

To access the Pattern Panel, select the Pattern button in the Toolbar.



  • Each pattern is composed of up to 16 Tracks laid out in rows comprised of up to 32 Steps across.
  • You can also modify the pattern's signature (see below).
  • Each track row from top to bottom corresponds to a drum kit track identified by the label to the left; the song’s drum kit is defined in the Toolbar.
  • Each track's instrument title is displayed to the left of the track.
    • To delete a Track: select it and hold for 3 seconds. Tracks will vibrate and an X will appear in the upper right-hand corner. Select the X to delete.
    • To add a Track: If there are fewer than 16 tracks, a New Track button will appear below other tracks. Selecting this button launches the Track Customization Kit (see below).

SignatureThe time signature (also known as meter signature) is a notational convention used in Western musical notation to specify how many beats are in each measure and which note value constitutes one beat.

There are various types of time signatures, depending on whether the music follows simple rhythms or involves unusual shifting tempos, including: simple (such as 3/4 or 4/4), compound (e.g., 9/8 or 12/8) or other meters. You can also choose to be in triplets mode.

To change the Signature, you can:

  • Select the top dialog (16 as shown above) to type in the number of steps in your pattern or
  • Select the bottom dialog (4/4 as shown above) to access the interface below:

Edit Mode Edit Mode: Draw/Select Toggle Button

Draw Draw: To Draw a step, select the Draw icon.
  • One click on a Step assigns the current mode value to a step; one click to a pre-assigned step erases the value.
  • Click and hold to see the current step value in the Toolbar display; you can also modify its value interactively with the Pattern Modifier Slider.
  • Click and drag to paint the value of the initial step (including an empty step) to other steps.
  • Changing the Pattern Modifier Slider while painting steps interactively creates variations in current Step Mode value, such as shown above.
  • You can paint steps in multi-touch.
  • HINT: To delete steps, create a rectangular Selection Set with two finger (see below) and click 3 times. For more radical interventions, you can use Delete in Automations.

Select Select: To displace or copy steps or a selection, use the Select icon.
Important: displacing or copying step(s) does so in all four Step (VPPO) Modes simultaneously (see below).

  • One touch and drag to displace a step in any direction.
  • New in V1.1: Select a track title and the entire track is selected. You can move, copy, replace or selection as defined below.
  • Use two fingers to define a rectangular Selection Set in the Pattern.
    • One Finger Drag to Move Selection (clears the original selection below)
      • Once the selection is being dragged, you can toggle with a second finger tap to change the selection bounding box from:
        • blue (replace existing steps) to
        • orange (merge with existing steps)
      • Release the selection where you want it displaced.

    • Two Finger Drag to Copy Selection (leaves a copy of the original selection)
      • Note: Once the two finger drag has started, you can move the selection with just one finger.
      • Once the selection is being dragged, you can toggle with a second finger tap to change the selection bounding box from:
        • blue ( replace existing steps) to
        • orange (merge with existing steps)
      • Release the selection where you want it copied.

Level Pattern Modifier Slider

Touch and drag to adjust the level assigned to Step Modes (See below).
HINT: When in Offset mode, dragging the bottom up and the top down allows you to reverse the sound.

Step Mode Toggle Step Modes: Volume/Pan/Pitch/Offset Toggle Button

Scroll through the Volume, Pan, Pitch and Offset modes by toggling the button in the Pattern Modifier toolbar.
  • Volume (Velocity) is the loudness of the pulse from 0 to 127; default value is 100
  • Pan is its left/right balance.
  • Pitch is the frequency of the sound in +24/-24 semitones.
  • Offset controls the start and end of the pulse.
Velocity Volume
  • IMPORTANT: Only steps defined in Volume mode are audible!
  • The step color will tinted from yellow (min) to red (max) according to its variation in Volume (velocity).
  • Steps with values defined in Pitch, Pan or Offset modes have a different shade of gray so that you can identify them.
Velocity Velocity Velocity Pan, Pitch and Sample Offset
  • When in Pan, Pitch and Offset modes, steps with Volume (Velocity) have a white highlight on the bottom.
  • Drawing steps in Pan, Pitch or Offset will automatically add steps in Volume as well if empty; however, Automations only add steps in the current mode and will not add steps in Volume Mode
  • Modifications to default values are also color coded for each mode.
  • NOTE: Volume and Pan values are multiplied by the master track Volume and Pan values defined in the Mixer.
  • NOTE: When in Offset mode, dragging the bottom up and the top down allows you to reverse the sound.

Track Customization Kit: Creating Custom Kits

DrumTrackHD's Track Customization Kit Panel

To access the Track Customization Kit, select Switch Tracks or New Track Button in the Pattern Modifier Menu.

When open, selecting a Track (on the left hand menu) plays the sound sample currently assigned to that track. The panel allows you to reassign sound sample(s) to a track - creating a Custom Drum kit, as well as allowing you to connect a Server on you iPhone/iPod to upload your own custom sound samples.

Custom Drum kits

You can assign one or multiple sound samples to the selected track by browsing the samples in the drum kits supplied or upload your own sound files to your iPad (see Custom Samples below). Scroll up and down for all the available sound kits.

Multi-sample: To add additional samples to the Track, click on the round + (Plus) Button

As soon as you select a sample:

  • The new sample is assigned to the track and will be playable.
    Select the Revert Button if you wish to cancel, but this will only affect the currently selected track. If you select a new track to customize in the meantime, the previous sample cannot revert back to the old one.
  • The following options are available:
    • Midi Note: This will be the Midi note played by the Track.
    • Group / ChokeBy: These two values are interrelated. Group allows you to assign a track to a Group using a numerical value; ChokeBy is used to specify which group will cut off this sample.
      e.g. In a song, you want to specify that CloseHitHat be cut off by the OpenHitHat. You would assign OpenHitHat to Group "1", and CloseHitHat be assigned "1" in the ChokeBy field.
    • Velocity Range: Velocity is the Volume of the sound. Setting the Velocity Range of a sample will allow you to make it play only if the velocity values are in between two set values. Velocity is sent in values of between 0 and 127, with 0 being the softest and 127 the loudest. If you want the sample only to play when it is a certain loudness, you could set the Velocity Low Range marker to 64 and the Velocity High Range marker to 127.
    • Probability: Allows you to alter which sample is played in a multi-sample track, expressed in percentages.
  • A Custom Kit is created, which can be viewed in the Mixer Panel.

IMPORTANT: The Custom kit is song-specific. If you wish to reuse your kit, create a "template" song with one pattern using your Custom kit.
