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.

continuum - I noted with interest your comment on using Switch Cleaner on the MWXT encoders. Could you please provide some details on how you cleaned them and the products you used. In looking at my encoders they seem to be fully sealed units, so I am keen to understand how you got cleaner into the encoder or exactly how you "cleaned" them. With Thanks in advance.

Has anyone had a problem with the Waldorf XT continuing to receive parameter control messages via MIDI even when it is set to "off" in Global/MIDI-page 2 parmeter control menu?

to answer affx - I've had my XT since new in 1998, and it's been in use almost daily since then.
About a year ago I noticed that some of the regularly used knobs (cutoff etc) were getting a bit jumpy and inaccurate. I took advice from a synth service engineer, and cleaned all the encoders with switch cleaner. They're all smooth and accurate again now - it's all good for the next 15 years :) I keep thinking about selling it, but nothing else comes close to the presence it has, and the degree of control. I'll be hanging onto it.

I've had my Waldorf XT for a number of months now and continue to be impressed with the sonic range and capabilities of this synth. It really can take you off to far off worlds, especially when you add some reverb.

I do find it difficult to tame at times (tends to have mind of its own), but with some tweaking, you can really find some sweet spots, sounds and textures.

Here is a recent ambient chillout /space music demo I made on Waldorf XT + reverb that showcases its "softer" side... I hope you enjoy it.

If anybody has this synth and the knobs are starting to fade in color, you can solve this by rubbing a little Armorall on them. I did this to mine and they look like new again.
