    Great sound but noticeable latency

    • Written by from Belvedere

    The Duet is a great sounding interface. But it suffers from the same USB latency problem that Apogee has solved with its big brother, the Emsemble. If you are using Duet for recording a guitar, for example, you will hear noticeable latency even at 96khz sample rate (of about 3-4 ms). The Maestro app will help with this, but it means you are monitoring your guitar without plug ins. If you are using Duet with MainStage you will have the same latency which makes it unusable for a live guitarist who wants to use MainStage to perform.

    To be fair, this isn't an Apogee problem. It is true of all USB interfaces and all older Macs because to process 96khz takes a lot of CPU power. I tested the Zoom Tac-2 Thunderbolt interface with my MacBookAir 1.7 ghz i7 at 96khz with a 32 sample buffer (lower sample buffers reduce latency but increase CPU load) and it had 1.3 ms of latency - which is unnoticeable to the human ear, thus equivalent to analog and wonderful to perform with live. But the CPU of my Air can't handle the plugin processing, e.g Amp Farm and a few effects. So it pops.

    We are at the threshold of a new era. With the Ensemble, Apogee has achieved 1.1 ms and with a new MacBook at 3.0 ghz a guitar player should be able to play "in the box" with a full set of plug ins and no latency in MainStage and Logic.

    I would be very surprised if Apogee doesn't release a new version of Duet with Thunderbolt with a lot less latency very soon. The Duet and the new Ensemble use the same 32 bit chip, so the same performance should be relatively easy to achieve.

    Let's hope a new Duet arrives soon.

    This interface will take the blanket off of your I/O. Opens up a new dimension and spaciousness to mixing.

    Duet is the Best!

    • Written by from Port Saint Lucie

    The Apogee Duet is an industry standard for a reason. The sound quality is amazing and so is the build quality - Duet is a tank! The fact that it can connect to iOS and Mac makes it extremely flexible as well. If you're using Logic, GarageBand or even Pro Tools the Duet is the way to go.

    The Best!

    • Written by from North Hollywood

    I love the sound quality you get from connecting your headphones or speakers to the Apogee Duet. With it's built in headphone amp and AD/DA converter you get that clean crisp sound that will make any audiophile smile. The beautiful design of the product with its full OLED display really makes it pleasing to the eyes. All it's other features like charging your iPhone/iPad while it's connected and of course having the capability to record, produce and mix professional quality music with this simple product make it one of the best investments I have ever made.

    not compatible with new 2013 macbook, imac and macpro

    • Written by from san francisco

    It's very unstable and not able to use on new models. It goes well with previous models though.

    Maybe it is the OS?

    • Written by from Woodinville

    Works great with my old IMac. I just got a new IMac with Mavericks and even with the new Apogee software/firmware etc. the Duet only works some of the time with the new IMac. I've had similar issues with 3 other audio interfaces that all work on my old IMac, but don't work consistently on the new one. Maybe it is just the OS, maybe the computer (which is new from Apple) not the Duet, but who knows?

    It is a really nice interface when it works.

    Doesn't Pass MIDI Correctly....

    • Written by from Orlando

    What can you say about Apogee. They have high quality stuff and the integration with Apple is awesome as they seem to be partners.

    I can't give it four stars, because it does not work with your expensive keyboard. What I mean is that if you have a Yamaha Motif keyboard, then the USB will not pass through to your device, even though the Yamaha Motif keyboards work with the iOS directly. In order for you to have MIDI and audio at the same time, you will have to purchase another device if you have a VERY POPULAR Yamaha Motif. It is confusing that my Yamaha Motif XF works directly into my iPad and iPhone using the USB MIDI, but the Apogee will not pass the USB.

    4-Stars if they fix this, but as it stands it is a major flaw in the engineering not to completely Pass through the MIDI and let the iOS handle which devices it wants to allow to work via MIDI.

    Portable High Quality

    • Written by from D.D.O

    Excellent sound quality compares to the best rack mount interfaces in terms of preamps and general sound quality . Price is a bit high, but you get what you pay for. If you are looking to record on an iPad or iPhone this is the perfect solution. It is the only device on the market that allows you to charge your i Pad while using it, all others (there are a few high grade interfaces that work with ios) you would need to stop working and wait to recharge, that would just kill any ideas or musical inspiration you have if for that one time you forgot to recharge.
    I found that the latency is great! You can play guitar or sing without any delays, even on an iPad 1 is usable.
    All in all don't waist your time to look and compare if you want portability, quality and peace of mind not having to recharge all the time then there is no contest, the only thing is the price tag.
