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

Delete the AUv3 plug-in app.
Restart macOS.
Reinstall the AUv3 plugin app.
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.

Finer Resolution for Dragging

By dragging horizontally, you can finely adjust the parameter values.

This function is not available when "Rotary Knob mode" is set to "Circular".

How to reset the parameter to the default value.

A quick double tap will restore the parameter value to its default value.

Rotary Knob mode

You can change the operation method of the rotary knob on the setting screen.

How to change which octaves are shown.

The keyboard displayed when running as a stand-alone App can be moved by dragging the keyboard scroll bar.

When running as a plug-in (AUv3), there is no keyboard.

Preset

When you first open the preset browser, you will see three folders: Factory, User and Program.

Factory: The Factory folder contains factory presets.
User: The "User" folder is where you can save your presets. Initially nothing is saved in this folder. When you import presets, they are also saved in this folder.
Program: The Program folder is a place to store presets that load when MIDI program changes are received. → Detail

Header Bar

Preset Browser

New Folder...: You can create new folders under the User folder.
Save As...: Save the currently loaded preset. Presets cannot be saved in the Factory folder.
New: Loads an initialized sound.
Recall: Recalls the sound that was loaded before opening the browser.
ALT: Displays a menu for editing the preset library.

Rename...: Rename the selected preset. Not available for multiple selections.
Export...: Export the selected preset. Not available for multiple selections.
Duplicate: Duplicate the selected preset. Not available for multiple selections.
Move: Move the selected presets.
Delete: Delete the selected presets.

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.

How to export sound presets

You can share your presets with other users.

Press ALT button.
Select only one preset or folder you want to export. You cannot press the Export button with multiple presets or folders selected.

To export multiple presets at once, select a folder containing multiple presets and press the Export button. Exporting in this manner allows multiple presets to be exported as a single file and the preset files contained within to be imported at once.
Press Export button
You can export the presets to Mail, iCloud, etc. via Share Extension

The size of the exported file is optimized and usually does not need to be compressed.

How to import sound presets

You can import presets exported in the previous method into the user presets folder.

Presets can be imported via other applications that support "Share Extension" such as file apps, mail apps, etc.
Imported presets are automatically saved in the "User" folder.
The method of Send or Share to an application via the "Share Extension" is different for each application that holds the exported presets. Please check the instructions for each App.

In the case of the File App, simply tapping on it will launch the standalone App and import it into the "User" folder.
Compressed files cannot be imported. Please uncompress the file before importing. The size of the exported file is optimized and usually does not need to be compressed.
If you import a "file exported by selecting a folder", the folder and all presets in the folder will be imported at once under 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.

Arpeggiator

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.

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

Settings

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.

File

Arpeggiator settings can be saved separately from sound presets. The saved arpeggiator settings can also be used with other iceGear synthesizers.
