    I agree with most of the reviews of this interface; there are connectivity/compatibility issues. For example, mine was largely inoperable until I downloaded the new drivers from the Alesis website. Once connected, the hardware monitoring is a great tool. Also, latency when using a decently small buffer (128, even 64 sometimes) is small enough that I've actually been able to use this to do sound for live shows, complete with VST compressors, reverb, etc. that I can't afford real versions of! This interface is hugely capable, and I've found that the built-in DI's are incredibly convenient. I can DI 2 guitars, and (through a box) a bass, then use the rest of the preamps for vocals and drums, for a gorgeous recording with almost no bleed-through, even in my tiny recording space. It might be pertinent to mention that this interface can show you how much fun the guitar VSTs like Amplitube and Guitar Rig can be. They really can sound incredible, and they're equivalent to so much gear! Anyways, if you buy this interface, be prepared to work with it, but if/when you can get it to work, it's immensely satisfying. Two last things: it doesn't say on the product page, but it comes with a nice 6 pin-6 pin FireWire cable! That was a pleasant surprise, because I had assumed I'd need to buy one. Also, some people complain that it can't record 24/192 with all the channels, but those are the people who don't know; even most pro studios don't do that. It really isn't necessary to record at such ridiculous fidelity for every track. It only succeeds in wasting a lot of hard drive space. In short, if you can work out the myriad kinks, this interface is wonderful, and is probably worth a try.

    this is a horrible product. i read all the reviews and saw that some people had really bad problems with it. but others were fine. i thought that since i had a brand new mac and a persistent spirit that i would be able to make it work. boy was i wrong. btw, i used it in both ableton live, cuebase 4, and garageband... none worked. i read the manuals, the online, i used common sense even. i got it to work for about 4 hours total in the 40 hours i tried to make it work. the sam thing never even worked twice in making it work. i tried any and every configuration i could. i finally called alesis and asked them how to make the product work. we talked for about 15min as they told me to try everything i already had tried. and then finally there was one thing left that he told me to do. and it finally worked... for 30min. called back. we talked for a while. they had no idea why it wouldnt work. and im pretty sure that i didnt have a defective product. i think they are all like this. please go buy something else. if you need to go cheap... then go presonus. they have consistently given me good sound for the cheapest price range. but do not buy this. please. save yourself the trouble, money, and future return.

    The Software Matters!

    By Joe Hero

    from NC

    See all my reviews

    Be careful of what kind of anti-virus protection you use when using the iO 26. When I first purchased this, I tried it with a Core 2 Duo processor at 2.2 GHz and 4.0 GB of RAM. I had a ton of dropouts whenever my computer accessed the internet. After I took Norton Antivirus off and replaced it with McAfee, the dropouts stopped. It also helps if you're not using a lot of wireless devices like wireless internet, wireless mouse, etc.


    Sonar Beware!

    Using Sonar 6 SE with Intel Core Two Duo (each processor 2.3 GHz) and a meg of RAM. Dropout, dropout, dropout...


    Does Evereything and does it good!

    By Anonymous

    from Undisclosed

    I had one for almost a year and I can say "It made me happy". At first when I first plugged it to my PC had some trouble, so I updated drivers and firmware and since that day untill today works fine whith my Lap-top in any place I record. The quality of the pre-amps is great they doesn't make any noise, the 2 discreete Headphones out is wonderfull to do monitor mixes even when you are working far form the studio. The Instrument imputs are fabulous and saves you from buying (and carryng around) A couple of DI-Boxes. The SPDIF input makes it work nicely with my dbx 386 pre-amp, adding 2 extra analog channels whith a nice, warm and detailed valvestate sound. And if comes the day when you need more than 10 channels you can buy a nice pre-Amp with ligthpipe out like the M-Audio Octane, for example, and get 8 more. there is no need to get another interface, The IO|26 Does it all and does it good!The only lack is the soft. The drivers are not very good, They work, but there are very faulty in some aspects and the Alesis crew doesen't look very much into it. They Don't update too often and don't give enogh support to people who had some serious issues. Although the monitor mixer is very handy for recording.In a few words this is portable, very affordable with handy features and very usefull. Could get better with better quality control and better drivers & firmware.


    Perfect for Project Studio

    By SeratoneRecords

    from Athens, GA

    See all my reviews

    I did a lot of research before finally settling on this interface. For 400 bucks, you get 8 simultaneous inputs with mic pres (which sound great), plus the expandability of 2 ADAT ins for a total of 26 simultaneous inputs. The output routing is very flexible and simple to use, allowing you to create many different headphone mixes. Very quick and easy to set up on my Intel iMac. I was recording within 15 minutes of opening the package. I've used this to record my band (Drums, Bass, and Keys) into Logic Pro 8 with very low latency and great sounding results. 5 inputs for the drum mics, 1 for my bass, and 2 for the Roland Phantom and MicroKorg synth.I would recommend this to anyone with a small to mid-sized home studio. It's now the centerpiece of my studio, along with an Axiom 49 as my midi controller/control surface and Logic Pro 8. I plan on adding 8 more inputs via ADAT through a MOTU 8pre. If you're thinking about it, just buy it. You won't find another interface with this kind of quality for this kind of price!


    Firewire issues, but

    By ML

    from Houston, Texas

    See all my reviews

    Once you get the firewire issues resolved it's a great interface. I was running with AMD CPUs and various chipsets. Only switching to an Intel CPU and chipset fixed the firewire issues for me. If you are doing serious recording, you really should not be using a whole lot of other USB or firewire devices other than a basic keyboard and mouse and perhaps some spare drives. Nice features are built in guitar DI and phono inputs.


    Exceptionally useful

    By supervajra

    from Bentonville, AR

    Although I had a few issues with the drivers for Leopard initially, ever since I updated the drivers I have been exceptionally pleased with the versatility, durability, utility and overall quality. I've tracked 8 analog ins at the same time in a variety of environments (school studio, home studio, live environments, etc...) and get good audio from all. This product works great. I use a variety of macs --laptops and desktops--and I get the same consistency in all environments with each mac, some of which are three years old. My only complaint is that I couldn't install Cubase because the cd that came with it was scratched.


    Great for Desktops recording, but...

    By John Galt

    from GA

    Not so great with Dell laptops...with latest drivers and firmware, this device had audio dropouts then froze on a Dell m1210 and Dell inspiron 1505e (both of which were updated fully with winxp, drivers, and kept clean of junk programs).These problems did not happen on my desktop machines. On the desktop PC's, this device was's features were as described.If you plan to use a laptop, be sure to try it out as soon as you get it...Hopefully new drivers will fix my issues.


    Awesome for Mac-based recording

    By DrumDr_71

    from Pocono Summit, PA

    When I first purchased this unit, I was a PC user. It has BIG issues with 64bit Vista. It runs fine with 32 bit vista.I later puchased an iMAC. I will say that the Mic pre-amps are awesome. I am using this unit in conjunction with Logic pro studio 8. The sound is GOD-LIKE. I have always liked Alesis, but they do need alot of work with thier tec support.


    Hit or miss on a PC

    By Disappointed Musician

    from Texas

    I purchased this and have had nothing, but problems on a PC. I know it is all about the firewire issues. I used the recommended firewire card, but still freezes my system, drops the device, or crashes. I have tried this on several different machines and even bought a new PC to try this out, it reboots that machine.The sad part is that it really sounds good and the pre amps are really quiet and clear. I guess if I had the money for a Mac I would'nt be writing this, but Alesis needs to do something about their drivers. They haven't updated the drivers in a while and they haven't taken responsibility or active steps to correct these issues.


    A++++ for Mac

    this is the best firewire interface at this price ever. hook this baby up with grageband and you are set. mic pres are great and it is so easy to use.


    Excellent Interface

    By BassRecorder18

    from Buffalo, NY

    This was the first interface I have ever used, and when I got it I wasn't exactly sure how well it would work. After playing with my computer for a little bit and working out the kinks, it worked phenomenally. I was able to record entire jams for over 1/2 an hour (haven't tried longer than that) without any stuttering or dropouts. Preamps work great and it is very easy to see what channels need to be raised or lowered to get a good mix. There is absolutely no delay b/w the interface and the computer, and the controls are very easy to use. I am very pleased with this product. I am even considering buying a second for an additional 8 channels.



    By Anonymous

    from Undisclosed

    I've owned this product for a year now and I've had nothing but trouble. I'm a computer engineer so issues are normally fixed but I am convince that this sound module is defective. I've had drop-outs, static, sudden reboots, latency and just so many problems I can't record a full session without issues. My suggestion is do not buy this unit it is garbage.


    great for the price

    By Anonymous

    from Undisclosed

    I bought this for my project studio and have been impressed with the sound quality for the price. I use it with my iMac, and had some trouble getting Logic Express to recognize it. However, I was able to track with Garageband flawlessly and then import those files with Logic for mixing. Enough channels for a fully mic'd drum kit and a scratch track for guitar or bass. A great mixing board for an entry level digital studio. Don't forget to use the phantom power switch for condenser mics.


    I hate this thing

    By Maggot Colony

    from California

    Hooked it up to my iMac with Garage Band and I get nothing but drop outs in audio along with a bunch of other noise. I installed the new drivers and they don't work at all. This piece of crap is going back!


    the firewire leader

    By getchapull

    from Dallas, TX

    Alesis is the pioneer in a full line of firewire products. Even though I dont use firewire devices much, this is the first one I used. I can't tell the diffrence between this and other firewire inputs except for the 8 mic ins (only used 4" center condenser, 2" left dynamic, 4" center high dynamic) for the price I'd rather go for a cheaper M-Audio box, but my producer likes it.


    Can't Go Wrong

    By JwoodAZ

    from Mesa, Arizona

    I picked one of these up, and it is truly a bargain for the price. The Pre's are very clean and sound terrific. I have used it on my Mac book Pro both Mac and Windows side without any issues. If you need 8 channels and don?t want to spend a whole lot of money this guy is for you!


    price/performance = amazing!

    By Cameron Fischer

    from Fort Collins, CO

    See all my reviews

    The guy below me claimed that the right 4 input didn't even work, well I'm willing to bet that he had the unit set to 192KHz which it is clearly stated in the manual that only the first 4 pre amps work in that mode. This interface works the best in the 96 KHz mode if you have a nice computer. Very transparent preamps, I was able to get good recordings wityh VERY bad mics, so if you put some good mics behind this thing you can make some amazing sounding projects without a doubt. I have noticed that it works the best with either Cubase SX or Nuendo. I've run into problems with the audio engine stopping in Sonar 7 Producer, but chances are it relates to the firewire chipset. That is one aspect people overlook when they talk down a firewire interface, make sure the card you have is optimal, and you aren't relying on either a knockoff card or stock mobo firewire. Get a card with a Texas Instrument chipset and you can't go wrong. Alesis recommends a Belkin card for Windows XP but I've had issues with that one, so go with anything TI.


    Looks great on paper

    By FunkyManchu

    from Chicago

    I've been using an M-Audio 410 for a few years and in an effort to expand my home studio I needed something with more inputs for mic'ing drums.Upon receiving the IO26 I noticed it didn't sit flat on my desk, or on the floor, or anywhere else. It wobbled quite a bit right out of the box. From there things just got worse. After plugging in the IO26 and attaching my studio monitors I noticed something very wrong. Every time ANY switch is flipped or Phantom power is engaged the speakers pop. If I had them turned up they would have been ruined. I have NEVER experienced a problem like this with cheap, expensive, digital, or analog gear. Unacceptable. Then came the software...I followed the instructions EXACTLY when installing the drivers which resulted in causing my system to crash. The FIRST time my computer has ever crashed since I bought it over a year ago. After trying every possible way of installing the drivers with out success, I gave up.Alesis does NOT have a convenient help-line, so unless you're unemployed and can call them before 3:30pm, forget about it.


    No 64 bit drivers

    By TomS

    from Michigan

    For the price, the fact that this has 8 inserts makes it potentially quite useful. Build is plastic, but I am sure will last with care. Big problem: won't work with 64 bit operating systems, since there are no 64 bit drivers available, and as of right now the people at Alesis have no plans to develop 64 bit drivers. Since Dell and others are moving to 64 bit OS, this needs to be addressed.


    the best thing

    By stef

    from Timisoara, Romania

    I own an alesis io 26 since 2 of april 2008 and i must tell you that is the best thing i ever had since now. it works perfectly with a laptop asus core 2 duo at 2,20mhz. 2G RAM, together with SONAR7. The only thing wich took me some time was that i spend about one hour to balance the buffer size to resolve the perfect latency. Congratulations for this product for the manufacturer...Alesis!
