Modelled on the popular DX series from the 1980s FM4 provides the same gritty sound, with a modern interface, and without being bound by the limitations of the original units.

Every aspect of the hardware — from envelope curves to sine-table sizes and quantisation errors to digital-to-analogue converters — has been meticulously analysed, in order to recreate the raw and dirty sound of the original units.

The interface has been carefully thought-out and is simple and intuitive, yet powerful — with every parameter being available on a single page. No menus, tabs, or jumping from page to page.

FM4 is capable of producing a multitude of sounds, ranging from punchy basses, crystal-clear bells, and lush pads, to organic textures, striking drums, and piercing leads.

FM Synthesis for beginners?

Korg Fan

This is a great app based on the TX81Z synthesizer! Despite what Primal Audio claims about the display bugs, I had no problem running it on an iPad Air 2. The presets are great and show what four operators can really do (beyond Sega Genesis sounds). If you have problems, get DXi instead. I am so happy that this app has every single parameter on a single screen!

Simple and full featured

Primal Audio really makes me smile with this one.. The FM4 is that classic frequency modulated synthesis that still has the power to rule the world of music today. Crafting a custom sound is easy and fun.

Excellent

A MUST have in your experimental audio quiver and the developers still support it another massive bonus.
