Waldorf Microwave XT

Waldorf Microwave XT Image

The Microwave XT is a great big orange polyphonic rackmount synthesizer. While combining the power of the Wave and the compact design of Waldorf's Microwave II, the XT adds a bit of knob-laden heaven. At first glance the top section completely resembles the 2-space rackmount version of the Microwave II. And then there are three more rack-spaces full of knobs and lots of knobs means lots of control.

As far as enhancements, the XT model has 20-bit DSP functions but that's about it. Its true power and features lie in the 44 hands-on knobs which make editing in real-time quick, easy and perfect for performance and studio work. All of the knobs transmit MIDI information as well!

The Synthesizer engine is relatively the same as the Microwave II and Wave synths that came before it. Digital wavetable synthesis and FM synthesis in which there are 64 waves that are mixed and combined into new sounds. The Microwave XT can easily emulate the sounds of the PPG wavetable synths as well as create squelchy acid-303 lines or boomy Moog bass. Also onboard is a nice arpeggiator, digital effects and more. The Microwave XT is definitely a powerful rackmount synth that can generate some highly unique and quality sounds. It is used by Nine Inch Nails, Danny Tenaglia, Underworld, Astral Projection, The Crystal Method, Mirwais, and Cirrus.

There is no place to get the polyphony increased on these any more. I checked with Waldorf tech support and the parts needed are no longer available. If you get this or any other legacy Waldorf synth with minimum poly, that's all it will ever be. If you want one with the maximized poly, you'll have to beg, buy, borrow, or steal one from someone who already has one. It is a very nice sounding machine, but most if not all of its abilities can be replicated by other machines old or new. It just depends on what kind of kit you want to put together.

I see this synth as a modern VCS3. It's one of the fews that can sound like real concrete sounds. My percussive patches can evoke nails rain or the sound of an an ever falling bookshelf. Sounds can go from vintage analog to messed-up digital whithin fractions of seconds. Carefully programmed, it can classified among the weirdest accoustic phenomenas in the world. Sounds especially good external analog effects.

It doesn't have a step sequencer like the Evolver does. You can program the arp tho.

Just a question: does this synth have a true step sequencer (like the Dave Smith Evolver or others similiar) or it's just an rearranger arpeggio?

i owned 2 of these and the mk1 also.The mk1 is without a doubt a better machine for retro elecronic sounds and also the ppg vibe , the xt whilst not that is its own beast and i think one of the most futuristic sounding synths i ever used.Its total sci fi and its character is distinctly space aged and extra planetary in a way the early versions are not partly due to the complex modulators and abilities.It really doesnt nail the mk1 or ppg sound at all an sounds to new for this but it does the most stunning glassy crystaline space city sounds i ever heard.Its like the machines made of some strange alloy and powered by artificial intelligence , its alive in way few synths ever are.It can be a hot and cold affair though , i sold 2 as the machine whilst stunning doesnt work so well with others some days and to be honest i can leave the user cold after a while.Its beauty is often a cold stark one.I would recommend anyone to try this , especially if you make space age and ethereal music.
