JAX - Walking On A Rainbow

Introduction price is available for a short time.

We have harnessed Apple’s cutting-edge hardware and native programming frameworks to create an Audio Unit that is truly unparalleled. From floating-point vector registers and Metal Performance Shaders to shared memory between the Audio DSP kernel and the GPU...

However — since all of this might sound a bit too technical — we didn't simply use these technologies as a means to an end; instead, we wrapped them in a musically meaningful and beautiful concept.

JAX 'Walking On A Rainbow' is our answer to classic frequency analysis tools — featuring a consistently musical implementation designed for real-time processing, imbued with a certain imaginative charm.

The songs we composed specifically for this purpose serve to underscore this very concept:

‘Open your mind and you'll find it's like magic.

When you take a step.

Oh

I'm walking on a rainbow.

Walking on a rainbow!’

WE ARE FRONTIERS.

You can expect more to cone and - you are welcome to join us.

Technical Note: The AudioUnit is smaller than 8 MB and consumes less than 1% of CPU power on an Apple M4 chip. No bloated third-party frameworks were used; this is a native development aligned as closely as possible with Apple's latest hardware (silicon).
