Moments in Mobile Music: 6 – Jasuto

Let me start this moment with a statement that I am (currently) not a modular synth guy. That may surprise some of you but I’ve resisted that temptation so far. Although it isn’t easy. However, I’m very interested in ideas around modularity and I’m not just talking about modular synths. So when the first modular synth arrived on iOS I was really interested. I didn’t hurt that it looked amazing too. The design was really appealing. I know that for a lot of people Jasuto didn’t make sense at first but when you’re u gave it a little time it was pretty easy to get into. Also it wasn’t modular in terms of its look and feel and by that I mean that it didn’t try to look like a physical modular synth. I think that was a major plus point for Jasuto too. In fact, in my view its design was and still is a stroke of genius.

I started using Jasuto when it first landed. It was a main stay of my iPhone 3G and after that on my ipad first generation. Which in fact I’ve still got around somewhere. Apps like Jasuto showed just how innovative the developer community could get. It was a real signal for people to do things differently and I think it made users realise just how powerful the platform was. Let’s not forget that this was even before Apple decided to call the os iOS.

Moments like Jasuto show us that our devices are capable of a lot more than we thought. They make us realise that this tiny computers give us the ability to go to places that were unavailable only a few years ago.

I still like Jasuto. I still use it and find it useful. I’d like to hope that it isn’t abandoned. I’d like to think that there’s another massive version in the offing. I live in hope!

14 apps I love: 10 – Jasuto


This is of course where modular on iOS really started. Jasuto was truly inspirational, and it still is. It took a little while to get used to, but actually not as long as you might think, and maybe without Jasuto we wouldn’t have some of the more recent additions to the iOS modular clan like Audulus, zMors Modular and AnalogKitv. Jasuto started something quite new.

It hasn’t been updated for a long time but hopefully that doesn’t mean the end, it’s gone like that before with Jasuto, so I still hold out hope that we’ll see it updated again, at some point.

If you’re in Frankfurt in April this workshop might be just for you

Especially if you’re interested in modular apps like Jasuto, because that’s what this workshop is all about! You can find full details here, but they are in German, as I suspect is the workshop itself.

The rise of the modular on iOS continues, KQ MiniSynth arrives


Well it probably comes as little surprise to you, it comes as only a small surprise to me that another modular joins the ranks of Audulus, Jasuto, zMors Modular, and AnalogKit. Modular is popular and people love it. So here’s KQ MiniSynth, and it’s universal too.

Here are the app’s details:

The maximum number of modules you can set is 100! ..Of course it depends on your device’s ability. You can install 10 Oscillators, make 10 series FM Modulators, and so on as you want.

  • External MIDI (e.g. iRig MIDI) is Supported.
  • Inter-App Audio is Supported.

This app implements the follow modules.

  • Oscillator
    • Oscillator Type A (Frequency Modulation)
    • Oscillator Type B (Pulse Width Modulation)
    • Super Saw Oscillator
    • Low Frequency Oscillator
    • White Noise Generator
  • Mixer/Amplifier
    • 4 Channel Mixer
    • Voltage-Controlled Amplifier
    • Sample-and-Hold Amplifier
    • Booster
  • Envelope/Logic
    • Envelope Generator Type A
    • Envelope Generator Type B
    • Inverting Circuit
    • Logical And (Series Switch)
    • Logical Or (Parallel Switch)
    • Maximum/Minimum Selector
  • Modulator
    • V/Oct Vibrator
    • Keyboard Level Scaling
    • Ring Modulator
  • Filter/Effector
    • Voltage-Controlled Filter (LPF/HPF/BPF/BEF)
    • Delay Effector
    • Reverb Filter
    • Compressor

The app was tested on iPod touch 4G, iPhone 5s, iPad 2, and iPad mini 3.
The Recommended Minimum Device: iPhone 5, iPad 2, or newer.

If you feel noisy or slow, try to decrease polyphony and increase buffer size on

The app costs $3.99 (£2.99) on the app store.
