Audulus 3 updated – modular synthesis app gets multi-channel audio I/O

Download from iTunes App StoreAudulus 3 logo 1If you are the kind of person who likes to program their own synth patches then an iOS music app such as Audulus is pretty much the ultimate playground. Not only do you get to program your own patches but – because of the modular nature of the virtual instrument – you also get to build the synth engine in the first place.

I reviewed Audulus 3 – a new version of the app with some significant additions and design restyling – when it first appeared and was very impressed. In essence, however, what Audulus provides you with a stock of virtual synth components that have various types of inputs and outputs that you can link to other nodes using virtual patch cables.

Audulus 3 is perhaps not an app for the preset lover.... but if you are in to DIY synth design, this is a heck of a playground to play in.

Taylor Holliday – the main man behind Audulus – also has versions of Audulus for OSX and Windows. However, the universal iOS v.3 has received a further update today with the arrival of v.3.4 on the App Store. The headline for this update is that support has been added for multi-channel audio input/output with the inclusion of two new nodes types; ADC and DAC.

The latest update includes two new node types for handling audio inputs and outputs.

If you want to integrate your world of hardware synths with the wonders of Audulus’ DIY software synth creation, providing you have a suitable multi-channel audio interface (and the video examples below use an Expert Sleepers ES-8 for this purpose; it’s DC-coupled whereas most audio interfaces are use AC-coupling) then you can now delve even deeper into the possibilities of Audulus to do so. OK, Audulus might not be an app for everyone, but the real hard-core synth nuts are going to see some real possibilities here for designing new sounds.

This kind of hardware/software integration can be used in various ways but the Audulus team have suggested some obvious examples in their press release on the update. These include sending and receiving simultaneous audio, modulation, and envelope CVs, sequencing analog synthesizers with volt-per-octave (VPO) signals and using Audulus as a multi-effect rack with a combination of inputs and mono or stereo outputs.

With suitable audio I/O hardware, the new node types can be used to configure all sorts of potential audio routing options within Audulus…..

I don’t have any suitable audio hardware to test these new possibilities for myself (nor, frankly, the ‘synthery’ expertise) but I’ve used Audulus enough to know that this is a powerful, modular, environment in which to build synths or sound design tools. Yes, the are other modular synth options – Ops or zMors Modular for example – but Audulus is perhaps the most well-established iOS modular environment and is most certainly a very deep experience. Going ‘modular’ might not be for everyone – for example, if you are happy to tweak a few synth presets then Audulus might not be for you – but dedicated synth-heads and wannabe (virtual) synth builders would get a real kick out of the software.

Audulus is a universal app, requires iOS9.3, is a 130MB download and is currently priced at UK£19.99/US$19.99; it’s a heck of a lot of synth designing potential for a pretty modest price.
