Martinic released Doctor Mix AI Synth, a free VST plugin made with ChatGPT.
It’s hard to escape the constant deluge of AI-related news these days. We recently featured Emergent Drums, a drum synthesizer that uses AI to generate new drum sounds, and the amazing Enhance Speech vocal enhancer from Adobe.
More AI-related news has emerged as Martinic introduces the Doctor Mix AI Synth plugin. Instead of using AI to generate sounds, this free synthesizer was developed using AI. It was made with ChatGPT and is a fascinating proof of concept of things to come.
If you’re interested in examining the VST code generated by ChatGPT, you’re in luck because Doctor Mix AI Synth is now open-source (available on GitHub).
Doctor Mix AI Synth is a monophonic subtractive synth by design. Whether you’ll like its interface or not is a matter of taste. You probably won’t mind the design if you’re a fan of Doctor Mix since you’ll be seeing Claudio Passavanti’s face as the most prominent element of the UI.
There are a handful of controls, as the synth is limited in scope. Oscillator waveforms are restricted to a saw wave, with no option for other waveforms selectable. The saw wave doesn’t seem to suffer from aliasing, but it’s difficult to tell since there isn’t really much in the way of modulation or syncing available on the oscillator.

A single filter and envelope round out the rest of the controls. The envelope is disabled by default and functions as the amplitude ADSR when toggled on. Filtering has minimal controls, with the cutoff, resonance, and a fixed LFO with rate and depth selectable. I didn’t test the waveform of the LFO, but it sounds like a sine wave when active on the filter.
Doctor Mix AI Synth isn’t going to ignite the world of synthesis. However, it serves as an interesting AI experiment that came as a result of a collab between Martinic and Doctor Mix. The synth is, of course, free to download, and early downloads get a 50% off coupon for the more full-featured AX73 from Martinic.
At the very least, it makes for a fun diversion with an arpeggiator, and I had a good amount of driving with free EON Arp from Modalics that we covered just a while ago.
Doctor Mix AI Synth is available for Windows and Mac computers, with available formats being VST, CLAP, and AU. There is no indication from Martinic as to whether it is available for Apple Silicon devices natively.
