SynthEdit 1.6 brings native macOS support and Linux experimental after three decades of waiting

Jeff McClintock has released SynthEdit 1.6, which brings native macOS support and experimental Linux support after three decades of being a Windows-exclusive application

Until recently, developing your own Synthesizer or effect plugins almost always required coding experience. AI has turned that premise upside down in recent months. Now anyone can do it, as evidenced by the flood of new releases.

Before that, visual environments like SynthEdit or FlowStone made plugin creation without coding possible – the grandfathers of modern AI-driven non-coding plugin builder tools.  And they are not dead. Out of nowhere, Jeff McClintock has just dropped SynthEdit 1.6 with native macOS support plus Linux in development.

SynthEdit 1.6

Before the AI ​​boom, there were few options for developing VST plugins without coding. The best-known were Synthmaker and SynthEdit. In the meantime, it’s also possible to convert Max for Live devices into plugins.

SynthEdit is probably the most famous example, having been available exclusively for Windows for over three decades. 

Today, Jeff McClintock released the beta version of SynthEdit 1.6, which now includes native Apple Silicon/macOS support. This means you can now run SynthEdit on a Mac (yeah, finally) and export your creations as VST3 and AU plugins, and ship them as a single signed .dmg.

I think very few people expected this to ever happen. It took over three decades, and now this is here. That’s not all. Alongside macOS support, the developer also includes experimental support for Linux with an x64 build that is not feature complete.

SynthEdit 1.6 also adds a new wavetable oscillator to the environment with built-in test waveforms (saw, sine, square, noise, and others), and an anti-aliasing mip at the top end.

Then, it also introduces resizable plugin windows for both VST3 and AU. So, the plugin can now resize cleanly, with DPI-aware refresh when the host changes scale.

Other additions include support for AI like Claude, WASAPI driver support on Windows, live hoverscopes, and project-specific skins.

The latter is a sister folder beside your project (e.g. mysynth.skin/) that is searched first for skins and fonts, with a _fallback skin for custom assets and a new “Browse to Project Skin” menu item.

First impression

With the possibilities that AI offers for automated plugin development, one could have agreed that SynthEdit or FlowStone are already on their way to obsolescence.

Especially with the limitation of Windows VSTs and the AI mindset of 2026: “if we still need to know how to make things when you can get something else to make it for you”. It’s certain that the new version 1.6 saves SynthEdit from oblivion at the last minute.

I think it’s great that the visual environment now supports both macOS and, later, also Linux. This will make many plugins that were previously only available on Windows cross-platform, like the linked KX-SYNTH-X16. Assuming the developer is still alive and willing to update it.

However, this means that many previously Windows-only plugins will be relaunched as cross-platform versions. This means even more plugins. Help, a new level of plugin oversaturation is on the way.

Nevertheless, I find it very positive that SynthEdit is now taking this path. I wonder if iOS AUv3 support will be added as well? 

The new SynthEdit 1.6 is available now for free as a beta version for existing users. A 60-day free demo is available on their new website.
