Drum Sequencer

The drum sequencer provides a drum set with ten instruments. It consists of a sequencer view and eight identical pattern composer views.
The tabs in the top row of each view can be scrolled horizontally. Touch them in order to navigate to the particular view.
Generating a drum track is very simple: at first compose the drum patterns that you need for your song. Then, in the sequencer view, put them in the timeline and finally press the “Generate” button. That's it.

When you launch the drum sequencer it opens with the sequencer view (tab “Seq”).

In the sequencer view you can do some general settings, including tempo, start delay, level and default velocity. Also in this view you put your drum patterns in the timeline and generate the track.

Tempo Set the tempo of the sequence in BPM (beats per minute).
Start delay The first few seconds are filled with silence.
Level Set the level of the generated audio. (Actually you attenuate the resulting audio signal in order to avoid clipping.)
Default velocity Set the default velocity of a newly added beat in the composer grid. A good pratice is to choose a medium value. That enables you to adjust the velocity of each single beat in both directions, harder and softer.
Timeline In the timeline you arrange your drum patterns in a sequence (see Timeline).
“Generate” Generate a drum track and close the drum sequencer (after saving your changes).
“Close” Close the drum sequencer. Asks whether your changes, if any, shall be saved.

You can add a pattern to the timeline by tapping at the wanted position. That can be either at an empty place in the timeline or between two existing pattern icons (touching them at their edge). The appearing context menu asks for which pattern to be inserted. The next menu asks for the number of repetitions. Finally the new pattern icon appears in the timeline.
The pattern icons in the timeline are sensitive on where they are touched. As described before, touching them in their left or right area opens a context menu for adding a new pattern to the timeline. When you touch them in their center another context menu opens. Now you can either delete this pattern from the timeline, or delete all patterns, or change the number of repetitions of the selected pattern.

The drum sequencer provides eight pattern composer views which can be opened with the tabs “1” to “8”. (Remember that you can scroll the tabs horizontally.)

In the top of the view you can configure the pattern.

Bars Set the number of bars for this pattern.
Beats Set the number of beats per bar. The tempo setting (beats per minute) in the sequencer view refers to these beats.
Subbeats Set the number of subbeats per beat.

Right below these selectors you find the composer grid. It has a row for each instrument and a variable number of columns, depending on the bars and beats settings.
The legend above the grid numbers the bars and beats in the format “bar.beat”. Each beat is sub-divided into a selectable number of sub-beats.
The legend on the left lists the available drum instruments.
The handling of the grid is as follows: touch a field in the grid in order to toggle the mark. A mark means that the respective drum instrument will be beaten at the specified bar/beat/sub-beat timing with the respective velocity.
A newly added mark appears with the default velocity. In order to change the individual velocity of a mark just double-tap on it and select a new velocity from the pop-up menu.
The grid can be scrolled horizontally and vertically if it doesn't completely fit onto the screen.

In the bottom of the view you find two buttons.

Play Play the pattern once (“preview”).
Clear Clear the grid. Before deletion you will be asked for confirmation.
