    Support for Apple Silicon Mac

    You can install this app on your Apple Silicon Mac(M1, M2...). Please note that this cannot be installed on an Intel Mac.

    This app supports only AUv3 plug-in format. It can be used with AUv3-compatible DAWs. Other plug-in formats are not supported.

    Important

    Before using an AUv3 format plug-in in a DAW, launch the app as a standalone, to ensure that it initializes correctly.

    If you have an AUv3 plug-in that does not appear in your DAW's AUv3 plug-in list, try the following steps

    1. Delete the AUv3 plug-in app.
    2. Restart macOS.
    3. Reinstall the AUv3 plugin app.
    4. Launch the standalone app for the installed app.

    Basic Operation

    Change selection by dragging

    In the selection UI consisting of lamps and button(s), you can change the selection not only by using the button(s) but also by dragging.

    The sound is not affected during selection by dragging. When you touch up, the drag selection will be reflected in the sound.

    Arpeggiator

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

    The arpeggiator rhythmically disperses MIDI signals from the host app or pressed chords from the on-screen keyboard. If you input a single note, the input single note will be repeated. When multiple notes are input at the same time, they are rhythmically dispersed as an arpeggio. Unless you use the "Hold" function, the arpeggiator will work only between note ON and OFF.

    Arpeggiator ON/OFF Switch (button on the top left)
    Switches the arpeggiator on/off.
    Step Length
    Adjust the number of steps. The arpeggiator will repeat the range of steps specified here.
    Style
    Sets the style of the arpeggiator.
    Swing
    Adjust how close to a perfect shuffle beat. The Swing parameter is only valid when the Rate parameter is set to 16th note.
    Loop Length
    The arpeggiator cycles through the pressed notes in the order set in Style. This parameter sets how many triggers to return to the first note.
    Example 1
    Notes held C,E,G
    Loop Length 8
    Result CEGCEGCE/CEGCEGCE/...
    Example 2
    Notes held C,E,G,B
    Loop Length 3 (less than the number of notes held)
    Result CEG/CEG/CEG/CEG/CEG/...
    The fourth note, B, does not appear in the arpeggio.
    Octave
    Sets how many octaves the arpeggiator will cycle through the held notes.
    Rate
    Sets the trigger speed of the arpeggiator.
    Accent
    Adjusts how strongly "Accent" affects.
    Gate
    Adjust gate time.
    Staccato
    Adjusts how strongly "Staccato" affects.
    KeySync
    When this setting is on, the arpeggiator's playback position returns to the beginning at note-on. When this setting is off, the arpeggiator's playback position is synchronized to the host app's beat position.

    Sequencer

    On/Off
    If set to "On", the arpeggiator will trigger a note at that timing. If "Off" is set, the previous note will be extended.
    Glide
    If "On" is set, the pitch will be smoothly connected from the previous note. The speed of this pitch movement follows the "Glide" setting in the Basic control panel. If the Glide knob is set to zero, there will be no Glide effect.
    Octave
    If "On" is set, the note at that timing will be triggered one octave higher.
    Accent
    If “On” is set, the note at that timing will be triggered with high velocity value. How much to change depends on the "Accent" knob above.
    Staccato
    If "On" is set, the note at that timing will be triggered with short gate time. How much to change depends on the "Staccato" knob above.

    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.

    The upper row sets the number of the note to be played counting from the top of the note-on state, and the lower row sets the number of the note to be played counting from the bottom.

    Imagine a style of playing in which the left hand holds the chord and the right hand plays the melody-like moving notes that appear in the arpeggio. If there is a way to count from the top, there is always a way to include the notes added by that right hand in the arpeggio. With the counting from the bottom method, it is impossible to locate the notes held by the right hand because the left hand does not know how many notes it will hold. Therefore, there are two ways to count from the top and two ways to count from the bottom.

    When seven or more notes are held down, no notes other than five from the bottom and two from the top can be included in the arpeggio.

    Example

    When you hold down C3,E3,G3,B3,C4 keys, C3 is 1st note, E3 is 2nd note, G3 is 3rd note. B3 is 4th note. C4 is 5th note.
