NEW FREE APP: KING OF FM Gives You Hit Synth & Electric Piano Sounds

They say the DX7 is used on more hit songs than any other Synth. There’s a catch – almost all those records were in the 1980s.

Inspired by DX7 folklore, I sampled a legendary-sounding DX7II from a famous studio. Then I released an app called FM Player, packed with those samples. That was nearly six years ago, and the experience has been jaw-dropping.

The response from musicians? Stupidly incredible.

It blew me away when Herbie Hancock played it in the Studio. It left me speechless when Grammy-winning producers started using it in their sessions—producers for Drake, Jay-Z, Kendrick Lamar, and more are rocking the app. Songwriters for Alicia Keys and studio musicians for John Legend are all over it too.

More importantly, we’ve received literally thousands of emails from grateful musicians. One message read “This app filled my eyes with tears when I first played through the sounds. It brought back memories of my youth, I was transported to a time when anything and everything was possible.”

Now, for the first time ever, you can have these sounds on iPhone and Silicon Macs. (FM Player was only available on the iPad). Plus, King of FM is more stable as an iOS/iPadOS AUv3. Want to rock multiple instances of this app in GarageBand, AUM, Cubasis, BeatMaker or your favorite iOS DAW? Go for it!

We’re not just talking about the sound of the past here. This app is the sound of today.



The Yamaha SY77 is a legendary synthesizer from the golden age of synths, first unleashed upon the world in 1989. This little-known synthesizer kicked some serious ass in the world of FM synthesis, earning its title as the
“King of FM.”

Legendary musicians like Brian Eno, Vangelis, Tangerine Dream, Jean-Michel Jarre, and Vince Clarke couldn’t resist the allure of the SY series. They hopped on these synths and cranked out some of the most groundbreaking tunes of their time. Lost to history, it’s no exaggeration to say that the SY77 played a vital role in hundreds of artists’ musical success.

Listen, the Yamaha SY series had a hell of a run…

So, when I kicked off the King of FM project in 2020, I initially got my hands on an SY99. But it just didn’t have that raw, unfiltered magic I was looking for—it was too damn clean. I couldn’t bring myself to create an app if the tone wasn’t right, so I shelved the project for a bit.

Then, I stumbled upon an SY77, and let me tell you, it had the sound I’d been searching for. I spent the next two years sampling the hell out of it, racking up probably 10+ gigabytes of SY77 samples on my hard drive (You might say I have a sampling problem).

But I didn’t stop there. I painstakingly sifted through the samples and cherry-picked the top 100+ or so multi-sample sets—those with the most captivating character. In the end, this app boasts 2 gigs of SY77 samples, compressed into a sleek package weighing in at under 400 MB.

Trust me, it’s the real deal.

And now, you can have these DX7 & SY77 sounds in the palm of your hand. Free forever.
