Pulse Code Inc brings updates to their Modular Synthesis and Rhythm Studio apps

It’s been a long while for Pulse Code Inc to update these apps. Modular hasn’t seen an app update since January 2015 and Rhythm Studio is the same. So what’s new in these updates? Well not a huge amount, but it’s good to see.

Both apps get 64 bit updates, and are now both Audiobus 3 compliant as well. So whilst these aren’t huge updates they’re worth having. What’s more Rhythm Studio is on sale too and down from $4.99 to $2.99.

Of course Modular Synthesis is free so no price drop there.

It’s good to see Pulse Code come up with updates, let’s hope that there’s more where these come from.

The micro modular is here, you need to take a look at Kastle from Bastl Instruments

I was lucky enough to bump into the guys from Bastl Instruments at Ableton’s Loop Summit. They were running workshops building their Kastle micro modular synth in the space I was using after them. I’ve bumped into these guys once before a few years ago at Musik Messe, but this time I got to spend a bit more time with them, and they’re really cool.

But enough of that for now. What I did do is get a chance to take a longer look at the Kastle synth and have a really long play with it.

The Kastle synth is tiny. I mean really tiny. It’s footprint is the same as 3 AA batteries. You can plug it into headphones and it sounds awesome. The real power of Kastle is its tiny patch cables, like patching any other modular but on a very small scale. It’s tiny patching capability gives it enormous power and verstility, but much more importantly it makes it loads of fun and that’s what’s really attracted me to it.

So let’s find out a bit more about what Kastle is from the Bastl Instruments site:

Kastle is a mini modular synthesizer with headphone output, 2 in/out ports for interfacing other gear and it runs on just 3 AA batteries. It is DIY friendly and ideal for beginners in modular synthesis, but it will add quite some unique functionality to any modular synthesizer systems. It delivers the fun of modular synthesis at cost and fits into your pocket so you can play it everywhere!

It has unique digital lo-fi sound and it can be melodic as well as very noisy and drony, soft or harsh. It is designed to be fun on its own but it is most powerful when combined with other modular gear.

Kastle is an open source DIY project which runs on two Attiny 85 chips that can be reprogrammed with an Arduino (google: “programming Attiny 85 with Arduino”). One chip is dedicated to sound generation while the other handles modulation. Several firmwares for the Attiny chips are available.

The Synth version combines complex oscillator and LFO with stepped waveform generator.

The oscillator section has 3 sound parameters pitch, timbre and waveshape – all under voltage control and with 3 different synthesis modes. It has a main output and a square wave output. Both can be used independently or combined. The 3 synthesis modes are phase distortion, phase modulation (also known as FM) and track & hold modulation. Each mode utilizes two oscillators. The Pitch controls the main oscillator, the Timbre sets the pitch of the modulating oscillator and the waveshape depends on the synthesis mode. The waveshape also controls the pulse width of the square wave output from the main oscillator.

The voltage controllable LFO has a triangle and square output and a reset input. The stepped waveform generator is inspired by the Rungler circuit by Rob Hordijk. It can produce 8 different voltages either in random order or in 8 or 16 step looping patterns depending on how the BIT IN is patched.

Here are the main features of the Kastle:

  • complex oscillator
  • 3 synthesis modes: phase distortion, phase modulation and track & hold modulation
  • pitch control with offset and CV input with attenuator
  • timbre control with offset and CV input with attenuator
  • waveshape control with offset and CV input
  • voltage controllable LFO with triangle and square outputs and reset input
  • stepped voltage generator with random, 8 step and loop 16 step mode
  • 2 I/O CV ports are available and can be routed to any patch point
  • the main output can drive headphones
  • 3x AA battery operation with power switch
  • open source
  • possibility of exchanging different LFO and OSC chips
  • the pattern on the sides changes and every unit is an original

From using the Kastle for a couple of weeks now I can safely say that it fantastic and enormous fun to play with and experiment with. I’d highly recommend it to anyone.

Audulus 3.1 arrives for Windows and Linux too!

Audulus gets just about as cross platform as you can get! Now with Audulus 3.1, Audulus is now available for Windows and Linux too, in addition to Mac, iPhone, and iPad.

“It’s not easy to be multi-platform, but I take pride in offering Audulus on as many platforms as possible,” says Audulus developer Taylor Holliday.

The Windows and Linux versions of Audulus have all the features of the Mac stand-alone version. Audulus for Windows also includes a VST plugin version.

Trial versions of Audulus for Mac, Windows, and Linux are also available. These trial versions have no time limit and can load any patch. To save patches, purchase the full version of Audulus.

Audulus for iOS has also been refined. A new context menu does not require a long-press gesture, making the Audulus UI easier to learn and quicker to use. Support for iCloud Drive makes it easier to share patches.

Audulus is a minimalist modular software synthesizer and effects processor. With Audulus, users can build synthesizers, design new sounds, or process audio. All with low latency real-time processing suitable for live performance.

Audulus for iOS can be used as a stand-alone instrument or in conjunction with Audulus for Mac, for a round-trip workflow between platforms. Begin a patch on the bus ride home and then bring it up on your laptop at band practice later that night – with iCloud functionality, moving between platforms couldn’t be easier.

Audulus 3.1 for iPad/iPhone is available on the App Store for $29.99.
Audulus 3.1 for Mac is available on the Mac App Store for $39.99.

Audulus 3.1 for Windows/Linux is available directly from audulus.com for $39.99. Purchase a single license for both versions.

Are modulars getting smaller, and is it important?

A question about modular synths and whether or not they are getting smaller or not

Audulus 3(.3) arrives with goodies

Audulus is one of the best modular music apps around right now, and modular, in all its forms is big, let’s face it. Audulus goes from strength to strength adding and developing, and, most importantly, responding to what its own community is asking for. Version 3.3 is a case in point. Here’s what’s new: New…

Video: Audulus + Gristleizer + Minimoog VCF + AD4096 + Ampex ATR-102

Video description: “In this video, I set up a simple 2 oscillator output from Audulus (no filters, no effects) – the majority of what you see on the iPad is the sequencer, clock, and the LFOs that are modulating various parameters. The oscillators from Audulus are sent into the Endangered Audio Research Gristleizer, and then…
