The new revolution
in synthesized sound

Introducing the world's best audio-to-synth technology.

Shape your sound.

Have you ever wanted to play piano notes by singing with your voice? Or use your bass guitar to control an Avalon Bassline, microKORG, or even vintage analog synths like the Arp Odyssey, Sequential Circuits Pro One, or countless others?  Now it is possible with our exceptional transient response and latency low enough for live performance.

Fastest audio-to-synth on the market

If you are an analog synth maker, from DIY to professional, you can benefit from the patented lightning-speed frequency-tracking technology of our DACO160 technology.  It gives you MIDI output, exponential pitch, zero-ripple envelope and gate CV outputs, three waves (square, sawtooth and our unbelievably pure sine wave), plus several other analog synth goodies.

Firmware runs on simple microcontroller

Our DACO160 algorithm runs so efficiently that it can be implemented in a microcontroller running as slowly as 70MHz, with the addition of only a 24-bit DAC for waveform generation.  The frequency-tracking IP is available for purchase with or without the CV, MIDI, or waveform outputs.

Works with ANY instrument!

The DACO160 technology features 8 “rate” settings which can be tuned to give optimum tracking performance depending on the instrument.  For guitar (yes, even bass guitar!) and voice, use a fast rate setting for punchy transient behavior and super-fast dynamics; for bowed strings and other harmonic-rich sources, use a slower rate setting to avoid tracking to the second and/or higher harmonics.


I always felt that sample based synthesis was not that intelligent… sampling is like only listening to what people say, not what they mean.

The best thing for me really is that, whatever you end up controlling with the ACO, it feels like your instrument.

And then came the time that people played the violin, but it sounded as a synth!

Your chip is the answer to years of search for me! I’m also happy that you’ve been receptive to my feedback. So few builders run their products by the artists they are building them for to see what they actually need!

This is one of the most versatile devices I have in my studio. It really is a Swiss army knife of synth connectivity.

I’ve used *literally* every hardware audio>CV unit that exists, going back to the 1970s Gentle Electric Model 101, as well as every wind synthesizer going back to the very first one, the Computone Lyricon 1, and this is the most expressive and accurate unit I’ve worked with!

OK here's where we get to the really revolutionary stuff... I hooked up an old MIDI interface that I had laying around and just gave the EVK a test drive with some software synthesizers and my head exploded!! The tracking is so much faster and dead on than any pitch to MIDI converter I have experienced!! It blew the Sonuus I2M out of the water!!
