7 Useful Patches For The AIRA Effector Modules

The AIRA Effector Modules are extremely versatile tools that have a lot to add to any modular rig. Using the AIRA Modular Customizer, they can be reconfigured to perform an almost infinite variety of functions. There are 31 different modules to choose from, including oscillators, envelopes, filters, delay and more. Here are some useful patches that will help you put these modules to use.

Riser Effect

The riser effect is very common in electronic music. It is usually used during a transition, but can also be used as a sound effect. It is created by sending white noise into a filter and sweeping the cutoff frequency. The sweep can be controlled using an envelope generator.

Sub Oscillator

This simple patch creates a tone that is one octave below the note that is sent into it. The output can then be mixed with the sound from the original oscillator. This thickens up the sound, and is especially useful for bass patches.


We already showed how to divide down to get a note that is one octave below. The same patch can be used to multiply the frequency up instead. Multiplying by 3/2 creates a note that is seven semitones above the original. This is a fifth in the scale. It is commonly used for soaring lead sounds, but can add lushness to any patch.


In addition to effects, the AIRA modules can be used to sequence notes on other modules. This patch shows how to use an LFO and sample and hold to create repeating note patterns.

Envelope Generator

You can never have too many modulation sources. This patch shows how the ADSR envelope generator can be used to control external modules. The potentiometers are patched to give control of the attack, decay and release from the front panel of the module.

Random CV

A random control voltage (CV) can be used to add variety to an otherwise repeating pattern. Use this patch to create it, and then send the CV to the parameter that you want to control. Alternatively, send it to one of the outputs and control an external module.

Mini Mastering Suite

A bit of equalization and compression can go a long way to help make a track sound polished. This patch demonstrates how to make a simple mastering suite with controls on the front panel of the module.
