Alesis Fusion

Alesis Fusion Image

The Alesis Fusion is a synthesizer workstation packed with features for the modern keyboardist. Released in 2005, Alesis managed to cram four powerful synthesis engines and an 8-track, 24-bit hard disk recorder into the Fusion's sleek, silver frame. The types of synthesis on offer include Sample Playback, FM, Virtual Analog (VA) and Physical Modeling – all powered by three floating-point Texas Instruments digital signal processors. It comes in 61-key synth action (6HD) and 88-key weighted (8HD) versions.

The Sample Playback engine lets you create four oscillator patches from either ROM multisamples or your own custom samples. Your samples can be recorded in through the dedicated stereo port, or loaded in via compact flash/USB; you can then edit and store them on the Fusion's large hard drive (40 or 80 GB). Import of WAV and SoundFont is supported, opening up a massive world of sounds. With 64MB of RAM, expandable to 192MB (and tricks available to double the usable amount of RAM) you won't fit a massive orchestral library in this synth, but for most sound design and live applications it will be plenty. Your samples can then be shaped using the Fusion's plethora of filter types, envelopes, and its massive mod matrix – nearly anything can be routed anywhere!

The six-operator FM engine can give you those DX-type sounds, full of character. However, it isn't compatible with DX SysEx, but you can still have a lot of fun creating your own sounds. The VA engine is very powerful, with many similarities to the Ion/Micron line! There are three oscillators with multiple wave shapes, FM, Sync, PWM and 20 different filter types including lowpass, bandpass, highpass and a 4-band EQ for every patch. The Physical Modeling section includes both a Wind and a Reed model, and while not amazingly realistic, they can be abused to create some very strange pads!

Putting all these synthesis types together, you start to see the power of the Fusion. Using Combis you can mix and match all of them, run them through effects, create massive evolving soundscapes using SoundFonts mixed with physically modeled wind and big VA strings, and more. Trigger loops and arpeggiators with one hand while doing a six oscillators thick lead synth freak-out with the other, the possibilities are staggering!

The effects section is OK. The distortion is a little weak and needs tweaking to get really gnarly results, but the bread and butter effects are all decent enough. The Hard Disk Recorder and Sequencer are basic but quite useable as a musical sketch pad. For example, if you and a guitarist wanted to jam something out, you could record your keyboards as a MIDI part to the sequencer, and then record a guitarist’s amplifier through one of the 8-track HD recorder's inputs on the back of the machine. Speaking of inputs, connectivity is generally good with eight quarter-inch inputs for the multi-track, stereo sampling in, two main outputs, two auxiliary outputs, MIDI, USB 2.0, all the things you'd expect on the back of a modern keyboard.

With all these features at a price point under $1,000, you'd think that this synth would be massively popular. However, early in its life there were some annoying bugs in the firmware, and some features were initially under-developed, such as the pattern-based sequencing. Although Alesis did a great job of releasing regular updates over its first three years, the Fusion's reputation became tarnished enough to blow it into obscurity.

The Fusion isn't perfect, it has issues like any piece of hardware, but for the price they can be had today, they make a wonderful performance keyboard, sound-design tool, and all around synth.

Bought the Fusion in 2006 and i love it! This is a very underrated synth-workstation. There is so much you can do with it soundwise, it is really staggering! I See this board more as a very good synthesizer than a workstation, because the sequencer never got implemented very well. There are still a few functions in the sequencer that not work very well, for example the list-editing of your tracks. When selecting a note you don't hear it playing. This makes editing very hard. Also the timing when recording a midi track is not that good.

I honestly think Fusion (expecially 8HD) will be a very sought after classic in the future.

Sure, it's got it's share of minor bugs, cryptic UI and technical issues, namely the power source and display. Despite all that it's a great sounding and very capable instrument with visual appearance that sets it apart from almost everything else.

I chased mine for over two years and now that I have it I will not be getting rid of it. It sounds fantastic and has so much under the hood that after nearly a year I feel I haven't even scratched the surface yet.

Worth checking if it works for you.

I can't believe nobody is mentioning the fact that it is probably the ugliest thing with keys ever built. Did the design department use a rejected design for a Volvo dashboard? I love my Alesis Micron and i have tons of respect for the team behind it, but this is just too ugly!

The power supply is the Fusion's weakest link. Plus you can't get the part anymore. If you can find a Flex ATX 200w power supply or a low power atx in general it will power it better then the original. Alesis/Akai/Numark should allow the O/S to be open source as well.

Alesis really had a great design department but from there the rest of the company was lacking. They started with effects like Quatraverb and went onto mixing boards (boy did they [beep] ) and then onto ADAT units and keyboards. They put out some great keyboards like the A6 Andromeda and Fusion, but quality issues and bugs put them to their death. I never had anything from Alesis that lasted more then 4 years with regular use. It is a shame, they have great ideas but no quality.
