Tips

  • Pressing the patch display box will bring up the SFZ file selection screen.
  • Pressing the downward chevron icon next to the patch display box will bring up the file-related menu.
  • After specifying the SFZ file, you must select a folder. To avoid the folder selection screen again, specify a folder in the upper hierarchy that contains all SFZ files.
  • When “Control” (third option on the menu bar) is selected, the control button changes to a panic button. Pressing the panic button will stop any currently playing sounds.

Menu Descriptions

  • Load file

    This opens the file selection screen, just like when you press the patch display box.

  • Edit file

    This opens the file editing screen. Since SFZ files are text files, you can edit them.

  • New file

    This creates an example SFZ file. Please specify where to save it.

  • Specify SFZ folder

    To obtain permission to load the current SFZ file, specify a folder higher than the SFZ file. This does not load a new patch.

  • Load file

    This opens the file selection screen, just like when you press the tone display box.

  • Open SFZ folder

    This opens the folder in the Files.app included with iOS/iPadOS.

Option Descriptions

Control

Key transpose

This is the transposition function. It shifts the input note key by this amount.

Engine

Max voices

This indicates the number of voices that can be played simultaneously.

Preload size

Specifies the size of frames to preload samples. Increasing it allows sounds to be played without interruptions during delayed loading but consumes more memory.

Sustain cancels release

Recreates a Linuxsampler behavior where pressing the sustain pedal (CC#64) puts the envelopes from release states back to their sustain states.

Rendering quality

Sample

This is the quality of sample playback. “Offline” refers to the quality during offline rendering. Quality and load increase in the order of Nearest, Linear, Polynomial, Sinc.

Oscillator

This is the quality of waveform generation. “Offline” refers to the quality during offline rendering. Quality and load increase in the order of Nearest, Linear, High, Dual-High.

Other

Theme

Specifies the appearance. Options include Light, Dark, and System.

Load image

Enables “image” and “image_control” opcodes which specifiy the background image.

Add reverb by adding opcodes

Automatically adds reverb OP codes when loading SFZ.

Add expression control

Adds the expression control (CC#11). The default setting is on.

Opcode blocklist

Specifies opcodes to ignore. In the editing screen, please specify one opcode per line.

Control range

You can select the control range from 0.0 – 127.0, 0.0 – 128.0, or 0.0 – 100.0. When using MIDI 1.0, 0.0 – 127.0 is recommended. For MIDI 2.0 HD values, 0.0 – 128.0 is recommended.

MIDI channel

Specifies the MIDI channel. Omni receives on all channels.

Use MIDI 2.0 HD values

Enables MIDI 2.0 HD values. It’s recommended to turn off if using a device that doesn’t support MIDI 2.0.

MIDI source

Specifies the MIDI input device. You can choose Virtual MIDI.

Multi out display

Enables multi out level meters. Requires rebooting the Audio Unit.

Bluetooth MIDI

Opens the Bluetooth MIDI settings screen.

Run in the background

Allows the app to run even when in the background.

Prevent sleep

Prevents the screen from dimming.

Audio buffer size

Specifies the size of the buffer that processes audio. Increasing it provides more stability but introduces more latency.

MIDI time offset

Delays the received MIDI signal by this amount. It’s expected to stabilize jitter.

Horizontal screen (iPhone)

Forces landscape mode on the iPhone.

Tuning

Scala File

Specifies a Scala format (.scl) file containing the pitch of the scale.

Root key

Specifies the root note of the scale.

Frequency

Specifies the frequency of A4.

Stretch

Specifies the intensity of stretch tuning. Stretch tuning refers to tuning where the frequency over one octave is greater than just doubling, resulting in pitches that sound more natural to the human ear.

12-Tone scale (A – G#)

Specifies the difference from the equal temperament for each pitch.

Default

Save as AU default

Saves the current settings as the default values for Audio Unit.
