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 Mail, iCloud Drive 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.

The presets saved in this folder are also displayed in the preset list of the AUv3 host.

About the presets made with version 1

When you launch version 2 of the APP for the first time, a folder named "(Old Version Presets)" is created in the "User" folder, and the preset made with the old version is copied into this folder. This process will not be executed even if you launch it as AUv3 plugin.

If the old version preset does not appear in the "User" folder, please try the following.

Back up the version 1 preset files to Mac/PC

About File Sharing on iPhone, iPad, and iPod touch (https://support.apple.com/kb/HT201301)

  1. In iTunes, select App from the list in the "File Sharing" section.
  2. If you drag files from the Documents list and drop them onto folders or windows on your computer, they are copied to your computer.

Restore the version 1 preset files saved on the device

  1. Restart the device (https://support.apple.com/kb/HT1430)
  2. Open iOS Settings App from iOS Home screen
  3. Scroll down and display Redshrike settings
  4. Turn on the "Convert" switch
  5. Close the setting application
  6. Launch Redshrike of App version (Not AUv3)
  7. If the Redshrike App succeeds in converting the old version data, a folder named "(Old Version Presets)" will be created in the "User" folder of the sound preset, and there should be presets converted in that 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 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.

  • 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
