The Endorphin.es Airstreamer 4 Black is an envelope generator module for Eurorack systems that offers multiple features, including looping, ASR, and AD modes. It is a fantastic addition to any set up due to its unique capabilities.
One of the most notable features is the CV control over the fall, which allows for decay and release control. Additionally, the continuously variable shape over both slopes without stretching the slope's duration in time makes it easier to achieve the desired effect. The 224 kHz sample rate guarantees low-aliasing CV generation, which produces a cleaner and more accurate sound.
This module offers bipolar and unipolar outputs, as well as an end-of-cycle output. The audio rate oscillation in cycle mode allows you to utilize it as an oscillator, which expands the module's functionality. The polarizer knob with an additional VCA input is another exciting feature that enables users to scale and invert the envelope.
Moreover, the Endorphin.es Airstreamer 4 Black without the need for external mixers, inverts or offset generators, allows for a compact sidechain envelope solution. This is a unique feature that sets the Airstreamer 4 apart from other envelope generators, making it an excellent option for those seeking a versatile and compact solution.
In addition to these features, the module also includes a slew limiter, S&H processing, and T&H processing for external CV sources. These added components make the Airstreamer 4 Black perfect for a variety of applications, from sound design to live performance.
Overall, the Endorphin.es Airstreamer 4 Black is an excellent envelope generator module that offers robust and unique features for Eurorack systems. Its broad range of capabilities and compact size make it a module worth considering for any electronic music enthusiast.
Example Usage
If you’re a novice user of the Endorphin.es Airstreamer 4 Black and you want to create a simple envelope, start by patching the 1 v/oct input to an oscillator and connecting the bipolar output to a VCA that is controlling a sound source. Adjust the attack, decay, sustain and release controls to shape the envelope accordingly. You can tweak the envelope further by using the polarizer knob and the additional VCA input. Experiment with the ASR and AD modes to get different envelope shapes.
An intermediate-level usage example for the Endorphin.es Airstreamer 4 Black could be using it as an ASR envelope to modulate a filter cutoff frequency in a patch. By patching the Airstreamer's bipolar output to the filter cutoff input, you can create a dynamic filtering effect that changes over time. Adjusting the ASR mode's attack and release times can control the filter's opening and closing, respectively. The Airstreamer's looping feature can also be engaged to continuously modulate the filter, creating an evolving and cyclical sound. Using the polarizer knob with an external CV input can also further shape the envelope to fit the desired effect.
Further Thoughts
One creative way to use the Endorphin.es Airstreamer 4 Black is as an audio rate oscillator in cycle mode. By utilizing the continuously variable shape over both slopes without stretching the slope's duration in time, this envelope generator can produce unique and complex waveforms that can be manipulated further with external CV sources. The low aliasing CV generation and 224 kHz sample rate also ensure high-quality audio output. Try experimenting with different external CV sources, such as a random source for S&H processing or a sequencer for T&H processing, to create dynamic and evolving sounds with the Airstreamer 4.
