How to reset the parameter to the default value.

Global Settings

  • MIDI Learn
    1. Enter MIDI Learn Mode by tapping the MIDI Learn button.
    2. Adjust 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.
  • Settings

    • Sync Method
      • Internal Sync
      • MIDI Sync
      • Inter-App Audio Sync
      • Ableton Link
    • Tempo
    • Tune
    • Transpose
    • Pitch Bend Range
    • MIDI Input Ports
    • MIDI Channel

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

    • Audio Buffer Size

      The audio buffer size affects the amount of latency and the CPU usage. Higher setting will reduce clicking 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.

    • Maximum Polyphony

      Lower maximum polyphony setting will reduce the CPU usage.

    • MIDI Mapping
    • Knob Mode
    • Keyboard Size
    • Restoring the factory presets

  • Volume
  • Glide
  • Arpeggiator ON/OFF
  • Keyboard Hold ON/OFF

Program

A sound you create is called a “Program". It dose not include the setting of Arpeggiator, Volume, Glide and MIDI mappings.

Arpeggiator

  • Program: defines which of the input notes is triggered

    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.
