Expert Sleepers USAMO Now Available


Expert Sleepers has announced that its USAMO (Universal Sample-Accurate MIDI Output) – a device designed to provide a sample-accurate, jitter-free MIDI output from your DAW – is now available.

The device takes a unique approach, sending MIDI information as audio, to ensure sample-accurate sync. 

The MIDI signal is generated by the USAMO software, a plug-in which runs as a virtual instrument (AU/VST/AAX, Mac & Windows), as audio in your DAW. The DAW sends MIDI to the plug-in; the plug-in translates that to audio and sends it to the USAMO hardware, via an output on your computer’s audio interface. The USAMO then reconstructs the MIDI and outputs it on a standard 5 pin DIN MIDI socket.

In addition to MIDI note and controller data from the DAW, the USAMO software also generates MIDI clock, Song Position Pointer etc. It can also handle Sysex.

Because the MIDI signals are generated and transported as audio, they are guaranteed to be sample-accurately synced with your audio, and free of the jitter often associated with computer-generated MIDI.

The USAMO is available now for £83.33 (excluding VAT) from the Expert Sleepers site.

  1. Does this mean Ableton now can output a super stable tempo information…? Is it possible to hook this up with lets say 4×4 interface and have same signal going through 4 outs even if the interface is still connected via usb on your computer… USAMO MIDI OUT to 4×4 MIDI IN…4×4(still via usb to mac) …

    1. Any MIDI hub that will run in ‘stand alone’ mode will work with this output. I’m curious though, does this device support a full 16 MIDI channels (or more??)

  2. Man, that’s some good news here. Was scratching my head how to get my Midi more reliable from the daw. First thought of an external Midi-Clock and daw as slave but this might fix some problems though..
    thx expert sleepers

  3. This is amazing and affordable. The Innerclock stuff is too expensive to delve into and I assume this essentially does the same thing.

    1. The software plugin converts the midi data to audio and the device converts it back to midi. That’s the only way to get stable midi out of a daw, because our expensive computers don’t prioritize midi data like they do audio. Apple could fix this but apparently never will, so this device is a crazy work-around.

      It works perfectly, but it means you need a spare audio channel on your i/o. If like me you are currently using a Duet or similar 2 channel interface, you will have to upgrade.

  4. Sure, I get that, but I’m not talking about sending a midi signal, why not send the audio signal down the usb connection? Surely that audio has to go to your sound card via a usb (or other) cable anyway right?

    Don’t mean to criticise, I just don’t quite get it! 🙂

      1. The audio signal should be the same as used for the rest of you external instruments to get all
        latency involved and at least a latency free mix.
