    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.

    You can share your presets with other users.

    1. Tap ALT button.
    2. Select only one preset or folder you want to export.
      You cannot export with multiple selections. By selecting a folder containing multiple presets and pressing the Export button, you can export all the presets in that folder at once.

    You can save presets created by other users in your user presets folder.

    • You can import presets via the File App, Mail and other applications that support Share Extension.
    • Imported presets are automatically saved in the "User" folder.

    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 program 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.

    Global Settings

    You can open the settings screen by tapping the gear icon on the top right of the screen.

    NOTE: On the plug-in mode setting screen, only the items that can be set are displayed. This image is the setting screen when launched as a standalone app.

    • Master Volume

      This setting is not affected by changing the sound preset.

    • Sync Method (Available when launched as an app)
      • Internal
      • MIDI

      You can set the synchronization method of the arpeggiator and sequencer.

    • Tempo (Available when launched as an app)

      When the synchronization method is internal sync, you can change the tempo of the arpeggiator and sequencer.

    • Timing

      Adjust the trigger timing.

    • Audio Buffer Size (Available when launched as an app)

      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 (Available when launched as an app)

      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 (Available when launched as an app)

      You can set which MIDI input port to receive.

    • MIDI Input Channel (Available when launched as an app)

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

    • Bluetooth MIDI Device (Available when launched as an app)

      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.

    • Include the MIDI mapping settings in the sound preset file
      • When Saving:

        ON: Save the MIDI mapping settings in the sound preset file.

        OFF: Save the sound preset file without including the MIDI mapping settings.

      • When Loading:

        ON: If there are MIDI mapping settings in the sound preset file, it will be loaded. If there are no MIDI mapping settings in the sound preset file, the current MIDI mapping settings will not change.

        OFF: Even if there are MIDI mapping settings in the sound preset file, it will not be loaded.

    • Knob Mode

      How to operate the knob Switches between linear mode and circular mode.

    • Display in a pop-up window (Available when launched as an AUv3 plugin)

      Set whether to use pop-up display when running as AUv3. If this is set to OFF, the screen will not close even if you interact with the UI of the host app. Turn it off if you want to adjust the tone while playing the keyboard of the host app.
