Imagine friendly creation of custom synths and sounds by dragging visual nodes. Now imagine you can do that on a mobile device and your computer – and eventually combine the two. That’s the vision of Jasuto, and while it’s not quite there yet, it’s incredibly promising.

The laws of combinatorics predict that, on a regular basis, you’ll see countless soft synths that are slight variations of one another. With the iPhone/iPod touch gold rush in full swing, we’re starting to see the pattern repeat itself, just as it did in Windows and Mac plug-ins. Some are brilliant; others are just the usual variations on a theme.

Of course, even better is the ability to build exactly what you want out of the same buildings blocks. Powerful toolkits like Max/MSP, Pd, Reaktor, SuperCollider, SynthMaker and the like let you do this, but they qualify as the more-sophisticated Erector Set of synthesis. Sometimes you just want some simple, LEGO-style building blocks that cover the basics.

That’s why Jasuto looks so promising. It’s actually two pieces of software – a plug-in for Mac and Windows VST. Combine basic modules, and you get some powerful features, even on the iPhone:

Sequencers by definition traditionally lock musical patterns into repetitive, unchanging blocks of time. But a new generation of generative sequencers can instead form organic patterns that change and transform.

Nodal is a totally free-as-in-beer (closed-source) sequencer for composing music. (A license is needed for commercial use.) As the name implies, it uses a matrix of nodes to represent musical structure. The best way to understand what that means exactly is to check out the examples and give the app a shot, but is good fun – and capable of creating some lovely, unusual musical textures.

The good news now is that if you’re on Windows XP/Vista, you’re no longer left out of the fun: the app now runs Universal on Mac and on Windows, as well.

Aside from Windows support, also new in version 1.1:

• New, more polished UI
• Keyboard shortcuts
• Internal MIDI synth support on Windows

It does sound as though Nodal may not remain free-as-in-beer, but with some significant updates coming later this year will move into the cheap-as-in-beer territory. Stay tuned.

Composer and co-developer Peter Mcilwain sends along the video here with a live improvisation made in the software. It’s a bit Minimalist-influenced, but shows how you can use Nodal to drive some musical inspiration. Peter also explains just what Nodal means musically to him and the small but growing collection of users taking advantage of Nodal’s paradigm:
