1. Setup

The Setup tab contains controls and options that affect the behavior of features at other locations in FL Studio mobile as described by the tabs.

2. General settings


Polyphony defines the maximum number of notes that can be played simultaneously. High polyphony requires more CPU and can lead to stuttering/crackling in the audio output, but low polyphony can result in notes fading out too soon.

If it is set to 16 and at one point during playback, the song would require 17 notes to be played simultaneously, the oldest note will quickly be faded out to allow the new one to play. The required polyphony of a song depends on the number of simultaneous notes on all tracks, and heavily on the release times. When exporting a song to a wav file, a polyphony of 128 is applied.

Keep attack/release times on instrument change

Preserves the current (PAN, VOL, ATT, REL) settings on an instrument change for the selected track.

Loop region in the step editor

Loops the region of the Step Sequencer pattern currently displayed.

Lock interface orientation

Stops the interface from rotating with the device orientation.

Bluetooth mode (iOS only)

Output audio via Bluetooth. TIP: Remember you will also need to activate Bluetooth in the iOS settings and pair your device with the Bluetooth accessory (headphones or speakers). NOTE: Bluetooth audio output and Audio recording are incompatible so Bluetooth audio will be disabled if you enter recording mode.

Background audio (iOS only)

The Background audio option allows playback while FL Studio Mobile is running in the background. To send FL Studio Mobile to the background - Start a song playing and click the home button, and playback continues, even if you launch other apps. Battery usage - If background audio is enabled, FL Studio will drain your battery significantly faster than normal, even if the screen is turned off or if other apps are running. To save battery - press the power button to switch the screen off during playback of a song. To quit FL Studio from background - double tap the home button, tap and hold the FL Studio Mobile icon, then tap the red minus icon.

In combination with MIDI, background audio has several practical uses:

External Hardware (iOS only)

The hardware setup section indicates if compatible hardware is connected. In this case, the Configure button becomes active and shows a popup with hardware specific settings (iOS only).

Restore defaults button

Brings up a popup asking you if the factory defaults should be restored. This means resetting all preferences in the setup tab and creating a new song. Saved songs (i.e. all files in the projects tab file list) will remain unchanged.

3. Keyboard settings

Velocity control

Enable velocity to control the note volume while playing on the keyboard. The volume depends on where you touch a key (top = quiet, bottom = forte).

Modulation vs accelerometer

Set the X or Y tilt direction to act as a modulation source for MiniSynth.

Snap to white keys

If enabled, scrolling in the keyboard tab will snap to the nearest white key.

Allow touches between black keys

If enabled, white keys can be touched in the area between the black keys. Otherwise, white keys can only be touched on the area below the black keys.

German key labeling

The German key naming system uses the letter H instead of B and B instead of A#. If checked, key labels on the keyboard tab and the piano roll editor's display use this naming convention.

Auto quantization

To save time, quantization can be automatically applied after each recording on the keyboard. The default setting is off, meaning that the Bar Editor or the piano-roll editor need to be utilized in order to quantize notes. Keep in mind that automatic quantization can lead to undesirable results and is not undoable. It is recommended for bass and drum recording.


If you tap a C on the keyboard with the transposition set to +2, a D will be played. The transposition range of -11 to +11 semitones allows you to play in a different key without having to learn the melody again.

4. Pitch Bend

If the pitch bend effect and the accelerometer button in the keyboard tab are enabled, the pitch of the currently played notes can be influenced by tilting the device.

Unlike most MIDI sequencers, FL Studio Mobile stores pitch bend data per note, not just per track. This means that two simultaneous notes on the same track can have different pitch bend data (events). The big advantage of this method is that editing a note automatically affects the pitch bend data for this note, but does not affect any other notes on the track (other software sequencers commonly ask if you want to move the pitch bend data too, this is obsolete with this method).

In the piano roll editor, notes with pitch bend data have a different texture (a vertical color gradient).

Semitone slider

Set the pitch bend range with the semitone slider from +/-1 to +/-24 semitones.

Sensitivity slider

The tilt angle required to bend the maximum semitone range is controlled with the sensitivity slider. The text to the right of the sliders clarifies the behavior of the current setting (e.g. the device needs to be tilted 45 degrees to achieve a pitch bend of 8 semitones).

Pitch bend accelerometer axis

This knob selects if the pitch bend reacts to tilt in the x or the y direction. If you are holding your device in landscape orientation X is left/right and Y front/back

Pitch bend invert axis checkbox

Enable it to invert the behavior of the current accelerometer axis, e.g. moving down (instead of up) will increase the pitch.

Pitch bend record mode

The recording mode controls how existing pitch bend data is treated at recording.

5. Metronome settings


The volume slider controls the gain of the metronome tick sound.


Set how many bars a recording will be precount. This is useful if you want to record the first note at the very beginning of the song (beat 1.1). Without precount, there wouldn't be enough time to tap the record button and immediately play the first note. Additionally, precount helps to get in time with the rhythm before you start playing (recording).

For example if precount is set to 2 bars, the playhead position is at the beginning of the song (1.1) and you tap the record button, the playhead will count 2 bars from -2.1, -1.1 until the recording starts at 1.1.

Precount only at the beginning of the song

If checked, precount is only applied if the left song marker is positioned at the beginning of the song. If it is not checked and the left song marker is for example at position 7.1, a 1-bar precount will begin at 6.1.

6. Hardware Configuration Popup (iOS only)

The MIDI hardware configuration popup looks different depending on the kind of hardware connected. For the Akai SynthStation 25, it shows the battery level. For CoreMIDI devices, it presents parameters for input and output. Port selection is available for CoreMIDI devices only.

Multi-timbral Control Tips:

There are 4 ways of utilizing FL Studio Mobile's MIDI input & output:

  1. Apps that are CoreMIDI or Virtual MIDI compatible.
  2. Keyboard controllers made for iOS:
    • Line 6 Mobile Keys
    • iRig Keys
