Introduction

Thank you for purchasing the AIR OPx-4 plugin instrument. The AIR OPx-4 plugin is a four-operator frequency

modulation powerhouse, delivering the ultimate in FM sound shaping.

•Advance FM synthesis. At the source, each operator is capable of producing complex waveform results via

feedback, formant shaping, FM Filtering and FM shaping parameters.

•Dual multimode filter path with 23 different filter types

•6 envelopes with tempo-synced looping

•2 LFOs

•2 ramps

•3 insert effects slots and 2 global effects slots with dynamic effects. Choose from a huge library of 27 AIR

effects plugins including reverbs, delays, modulation, and distortion.

•Modulation matrix with 32 slots

•Sample layer for adding percussive attacks

This user guide explains the features and functions of the plugin instrument. For more information on using this plugin

with other software, please refer to your software’s documentation for adding and using plugin instruments.

Setup Section

1. Keyboard: Click this icon to enable or disable the virtual keyboard. When enabled, you can click these keys to

input notes, or view notes being played on an external MIDI device.

2. Tempo: Displays the current plugin tempo. To change the tempo:

•Click the number and use your keyboard to input a new value.

•Click and drag the tempo value up or down using your cursor.

•Click the Tap button at regular intervals.

3. Settings: Click this icon to open the Settings window, where you can set the following parameters:

•Output: Click this drop-down menu to select an audio hardware driver in your computer system. Click the

Test button to play a test tone for checking your audio output settings. (Careful! You should lower the

volume on your audio system beforehand.)

•Sample Rate: Click this drop-down menu to select the desired sample rate for your project. This depends

on the available sample rates of the type of MPC hardware you are using or of your audio interface (i.e.,

select 96000 Hz only if your interface allows a 96 kHz sample rate).

•Audio Buffer Size: Click this drop-down menu to set your audio system’s latency. Lower values result in a

more immediate playing response but also more CPU consumption. If you are working with larger projects,

this may cause audible clicks and pops. Higher values are more CPU-friendly but can produce more delay

between pressing a pad and hearing the corresponding sound. The ideal audio buffer size also depends on

your computer’s CPU performance. Experiment with this to find the best setting for your system.

•Active MIDI Inputs: Displays available MIDI input devices. To enable a device, check the box next to its

name.

•Bluetooth MIDI: Click this icon to open your system’s Bluetooth settings menu, where you can select a

Bluetooth-enabled MIDI device to control the plugin.

4. Menu: Click this icon to open the menu, where you can find the following options:

•Scale: Click here to select a value to scale the plugin window to a new size.

•Load Preset: Click here to load a saved preset.

•Save Preset: Click here to save the current preset.

•Open User Guide: Click here to open this User Guide.

•About: Click here to view plugin version information.

5. Preset: Click this drop-down menu to view the list of included plugin presets. You can also click the up and

down arrows next to this field to move to the previous or next preset.
