Professional feel and features combined in one powerful workstation.

The Alesis Fusion 8HD Keyboard Workstation boasts a revolutionary operating system, the Fusion OS, that is constantly being refined by Alesis and its developers to bring you the ultimate workstation available. It also brings together 4 different synthesis types with an 88-note fully weighted keyboard, 8-channel hard disk recording, sampling, effects, lots of expansion possibilities, and full-blown sequencing in one awe-inspiring machine.

At the heart of the Alesis Fusion 8HD is the Coldfire processor surrounded by 7 high-performance DSPs, giving you 4 synthesis types: sample playback, virtual analog, FM synthesis, and physical modeling. The sample playback synth type provides ultrarealistic play for instruments like grand pianos, drums, and guitars, etc. You can even make your own custom synth instruments by loading your own samples with the onboard sampler. The virtual analog synth brings you the sounds from the award-winning Ion and Micron virtual analog synths, as well as the actual-analog A6 Andromeda. FM synthesis gives you the ability to emulate many well known synthesizers of the 80s. For the physical modeling section Alesis uses the most advanced technology available today for synthesizing wind and reed instruments with incredible clarity.

The Fusion Keyboard is the only workstation of its kind that can save and load programs off of a hard disk (or the removable CompactFlash memory). By storing all your sounds on the internal disk you'll always have your programs available to you. You'll never have to load samples off a slow CD-ROM or floppy-disk.

You can also record up to 8 channels of 24-bit audio to the 40GB hard drive. The workstation's internal sequencer lets you edit your MIDI and multitrack recordings together just like on a computer. DSP effects can be applied to MIDI, audio, or both. You can transfer your mixdown to a computer via USB 2.0.

Upgradeability includes internal RAM (up to 192MB).

An incredible unit for professional recording studios, project or home studio, and even live keyboard players.

I played a very cool organ sound on it in a music store and got my attintion big time.


from Tn

I don't own one but, after looking at the artical and playing around with one in the music store, I was impressed with this board.Yes,It looks a bit different on the outside but offers a lot inside and a lot for the low price. I am going back for a second look when I get the chance.

Very cool for what I do


from Boston

I have to disagree with a lot of the comments of the other reviewer, as I find this board very appealing for what I am using it for (live performance-sequencer based single act). I too, thought it was odd that the sounds took a few seconds to load, but I downloaded the newest software, and this is not a problem any more. It may take a split second longer to load a sound than a conventional board, but it certainly is fast enough (by the time your hand gets back to the keyboard from pressing a preset, the sound is most definitely loaded, so what's the difference really?). The other reviewer didn't like the casing, but I think it looks really cool, and there is no doubt that it is built well (very solid). The keybed also feels good to me (a little on the light side as far as action goes, but very solid). The sounds are pretty good (not great, but Alesis has already posted some decent updates on the site, and I'm sure there will be more). I think the coolest part of this synth is the ability to add REAL AUDIO tracks to your performance. I have gone in and added background vocals (I have tried using the TC vocal unit, but I thought it sounded kind of fake), and even just doing that has made my performances sound so much better. I also play guitar (not that well, but hey, I AM a keyboard player!), and I added some acoustic guitar and even some real electric guitars to some of my sequences, and it is a whole new ball game! It really makes a huge difference. I guess it all depends on what you want to do with this board, but for me, it works great.
