Sound Preset

Preset Browser

Display order of presets

The display order in the preset browser is sorted in alphabetical order, with numbers from 0 to 9 first, then capital letters A to Z, and finally a to z. Therefore, you can sort the order by putting a number before the name.

  1. Tap ALT button
  2. Select the preset or folder you want to export
  3. Tap Share button
  4. You can export the presets to Mail, iCloud, etc. via Share Extension
  • You can import presets via the File App, Mail and other applications that support Share Extension.

Programs Folder

In the "Programs" folder you can define which presets will be loaded when a MIDI program change message is received. The program number corresponds to the order of the sound preset in the "Program" folder.

You can sort the order of the programn number by putting a number before the name. → Display order of presets

AUv3 host preset list

The presets stored in this folder can also be displayed in the preset list of the AUv3 host. On the settings screen, you can choose to display the factory presets or the contents of the program folder.

Basic control panel

The settings of the Basic control panel are saved in the sound preset.

  • Volume
  • Arpeggiator ON/OFF
  • Monophonic ON:Mono/OFF:Poly

    limits playback to one note at a time.

  • Keyboard Hold ON/OFF
  • Glide

    adds a sliding pitch transition between notes that are played consecutively.

  • Pitchbend Range

    Specifies the Pitch Bend Range in semitones.

  • Octave

    can transpose pitch up or down in one-octave steps.

Global Settings

  • All Note Off

    When notes get stuck, you can kill all notes currently playing by tapping this button.

  • Master Volume

    This setting is not affected by changing the sound preset.

  • Master Transpose

    This setting is not affected by changing the sound preset.

  • Master Tune

    This setting is not affected by changing the sound preset.

  • Microtuning

    You can change the equal temperament tuning scale to a different tuning.

  • Maximum Polyphony

    Lower maximum polyphony setting will reduce the CPU usage.

  • Sync Method

    You can set the synchronization method of the arpeggiator.

  • Tempo

    When the synchronization method is internal sync or Ableton Link, you can change the tempo of the arpeggiator.

  • Audio Buffer Size

    The audio buffer size affects the amount of latency and the CPU usage. Higher setting will reduce crackling noise at high CPU usage, but also cause more latency.

  • Background Audio

    If background audio is enabled, this app will consume battery power significantly even if other apps are running or if your screen is turned off.

  • MIDI Input Ports

    You can set which MIDI input port to receive.

  • MIDI Input Channel

    When the OMNI is OFF this app will receive only on the currently selected channel.

  • Bluetooth MIDI Device

    You can connect Bluetooth MIDI compatible controllers.

  • MIDI Mapping - File

    You can save/load MIDI mapping settings.

  • MIDI Mapping - Takeover Mode
    • None

      As soon as you operate the MIDI controller, it will be reflected to the parameter. If the MIDI controller value and the parameter value are different, the parameter value will jump.

    • Pickup

      If the MIDI controller value is different from the parameter value, the parameter value will not be changed until the MIDI controller value crosses the currently set parameter value. However, even in this mode, if the MIDI controller is operated when the parameter value is out of the range set by the MIDI mapping, the set parameter value jumps to the boundary value of the range.

Arpeggiator

Program Mode

The program row can be used when the style is set to "Program". It specifies which of the held notes on the keyboard will be played.

Example: When you hold down C3,E3,G3,A3,C4 keys, C3 is 1st note, E3 is 2nd note, G3 is 3rd note. A3 is 4th note. C4 is 5th note.

MIDI Mapping

You can assign the MIDI controller knobs to the parameters.

MIDI Learning Mode

  1. Enter MIDI learning mode by tapping the MIDI Learn button.

  2. Touch the on-screen control you wish to map.
  3. Adjust the slider or knob on your MIDI controller. (MIDI CC)
  4. Repeat above steps as required.

MIDI Map Setting Panel

In MIDI learning mode, Press and hold the knob or other control to open the setting panel.

To delete the assigned MIDI mapping, tap the control several times.

MIDI Map Range Setting

Save MIDI Mapping

You can save the created MIDI mapping from the setting screen.
