Audulus 3.4 Update Adds Support for Multichannel Audio/CV Output


"Audulus LLC is proud to announce the release of Audulus version 3.4 - a free update for all Audulus platforms* allowing users to access up to 16 audio and control voltage (CV) inputs and outputs through two brand-new nodes called ADC (analog-to-digital converter) and DAC (digital-to-analog converter).

Previously, Audulus users were limited to two inputs and two outputs using the Mic and Speaker nodes. Now, with the ADC and DAC nodes, Audulus users can take full advantage of their DC-coupled** audio interfaces, such as the Expert Sleepers ES-8 and the Universal Audio Apollo.

This means that users can now integrate Audulus seamlessly with hardware synthesizers and analog effects pedals using their computer or iOS device.

Some examples uses include:
Sending and receiving simultaneous audio, modulation, and envelope CVs to up to 4 Eurorack filters for true analog filter polyphony
Clocking multiple Korg Volcas at different speeds or divisions of a master clock
Sequencing analog synthesizers with volt-per-octave (VPO) signals
Receiving multiple DC signals from hardware controllers like CV joysticks and ribbon controllers for ultra-high-resolution control over your digital synthesizers
Receiving, quantizing, and sending out analog VPO signals
Generating LFOs and envelopes of any imaginable shape
Using stompboxes on a send & return within your Audulus patches
Cloning, adapting, and modifying true work-alikes of digital and analog Eurorack modules
Generating quadraphonic or surround-sound-style effects for keyboards and guitar
Receiving an analog master clock and generating divisions, probability triggers, or Euclidean-style rhythm sequencing (or mix of all!)
Storing, recalling, and rapidly switching between different modular synth patch routings
Analyzing a guitar’s pitch and volume envelope within Audulus and converting them to an analog VPO and envelope signal
Using Audulus as a multi-effect rack with 4 mono inputs and outputs or 2 stereo inputs and outputs (with an Expert Sleepers ES-8)

These are just a few of the possibilities Audulus users have explored so far. To keep up with patches and modules using the new ADC and DAC nodes, sign up for the Audulus user forum and download and share your patches there - http://forum.audulus.com

Users can also follow Audulus on Instagram, Twitter, Youtube, Soundcloud, and Facebook @audulus for tutorials, video clips, and sound samples of what the ADC and DAC nodes can do.

If Audulus users have any questions about how to implement the ADC and DAC nodes, they can contact Audulus at support@audulus.com

Happy patching from all of us at Audulus!

* Audulus iOS requires the Apple Camera Connector Kit to connect to the Expert Sleepers ES-8.

**Most normal audio interfaces are AC-coupled. AC-coupling prevents a constant DC offset from damaging speakers and headphones. DC-coupled audio interfaces like the Expert Sleepers ES-8 are not required to use all 16 inputs and outputs of an audio interface or aggregate device. DC-coupled audio interfaces are required to send and receive accurate DC-offset analog signals such as gates, VPO signals, and envelopes.


Example Videos of Audulus + ES-8



This picture shows a self-oscillating filter entering Audulus through audio input 4 of the Expert Sleepers ES-8 using the ADC node, and sending two oscillators through outputs 7 and 8 of the ES-8 using the DAC node to the Mordax DATA oscilloscope in XY mode."
