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.

Latest Fusion update!

Fusion OS is a completely upgradeable platform that will continue to improve with each and every release. There are now hundreds of new program sounds, mixes, and arpeggiator patterns, with more free sounds available via download. This update as well as all future updates to the software and the sounds can be found at:,59,0,0,1,0

Powerhouse workstation

By TheRaygun

from Reynoldsburg, OH

Comments about Alesis Fusion 8HD 88-Note Keyboard Workstation:

I recently picked up this board for use in my band. The Alesis is a superb choice as it is feature packed and extremely easy to use. The biggest thing is that the interface is well-laid out and customizable. The menus are intuitive and make it easy to get to your favorite tones quickly. The tone quality is top notch, and Alesis regularly supplies updates via their website. The keys are naturally weighted and make it a joy to play. The addition of the hard drive and the digital 8-track recorder are just icing on the cake. You will not find a better workstation out there period, but especially not at this price.

Integrated Package

By PeachtreeKeys

from Peachtree City, GA

Comments about Alesis Fusion 8HD 88-Note Keyboard Workstation:

Extremely pleased with the integrated package recording audio along with synthesized tracks for the value. Other alternatives were 2X if not 3X the prices. Holy Grail Piano is very nice and the simplicity of the user interface allows ease of use out of the box.


Top Notch

By Corey

from Florida

Comments about Alesis Fusion 8HD 88-Note Keyboard Workstation:

The fusion is a top keyboard, it has good sounds, particularly the piano, guitar and stand up bass. It has the ability to let you record audio with it making the sequence especially great for live playing. If you play country, rock, or gospel this is the part that will be most satisfying. You can play rythm to your live playing and have the vocal harmonies, lead guitar, steel, etc. recorded and they will sound as though they are in the room or onstage with you. I know that this unit is no longer in production, but, if live playing is your preference, this is the one to get before they go. Advice if you play this on carpet, be sure to put something under your feet to keep down static electricity, it will cause the unit to do some crazy things.
