6th month thoughts about the Waldorf Quantum

I would buy the Waldorf Quantum over and over

I think in my future synthesizer purchases, I will wait until a synth has been available for a year. Most of the time, issues will be firmware, but sometimes there are hardware revisions. That may be common knowledge but I’m an experience learner, ha! That said, critiques in this post should be properly weighted; the Waldorf Quantum is an amazing machine. Under my new 1 year policy, I would not hesitate to pull out my credit card and buy the Quantum today, and I have little to no regrets about having bought one 6 months ago.

The Quantum is definitely my stranded on an island with only one synthesizer (and electricity) choice. Even analog purists would be well advised to open their minds. Those without $4k to spend would be well advised to move mountains to get one. Those who are not ready to appreciate the value of a $4k synth yet, need to spend time with a Quantum. The Quantum is one of the few pinnacles of synthesis on the market today.

I think there are a few resolvable hardware issues in some 1st year Quantums. Aside from miscellaneous defects or QC issues which all new electronics are likely to have a 1% rate of, here are a few to be aware of.

  • Squeaky keys – This one is the easiest to fix. You don’t have to tolerate it or take pass on a used machine with the issue. This condition is common to many brands which use Fatar keybeds. The keybed just needs lubrication, check with Waldorf support or your dealer.
  • Touch screen sensitivity and/or dead zone – Most of the issues with this are firmware design, fixed in the 2.0 beta 9. You may notice in the image at top of this post, the 6 control areas on the left and right sides of the screen are redesigned to reflect more accurately that there are no buttons for selections like normal and mod; the whole rectangular area is a touch area/button, which once you understand that, makes selection a snap. The middle selector knob between save and previous has been programmed to scroll through selection choices much more accurately and easier than previous touch only selections. You could get a new screen through warranty that is purported to be more sensitive, however the firmware changes make a world of difference and you may not care. Likewise, many Quantums have a dead spot on the right 1/4″ of the screen that can be fixed with a screen firmware update (not to be confused with the OS firmware, this is completely distinct and not currently upgradable from SD or USB. A user upgradable screen firmware may become available in the future, but there is no guarantee at this point). I think most people will not bother to deal with repair of these screen issues since the beta take almost all the pain away. To replace the screen or update the screen firmware, you will need to ship the synth to a warranty center.
  • Voices with inconsistent resonance – See image at top of this post. I wouldn’t have even noticed this if I hadn’t read about it. Thanks to Paul Cotton, who provided these issue confirmation instructions and .wav files: Boot, load a patch > Init the patch > Turn off OSC1 in the OSC MIX (so audio will be just filter self resonance) > Left of the screen, change analog filter 1 cutoff to 67 and resonance to 85.5 , then repeatedly play middle c to cycle the voices. Before fix .wav / After fix .wav To fix this, you will need to ship the synth to a warranty center.

So I’m trying to decide if it’s even worth the bother to send my Quantum off to fix the 2nd and 3rd issues in February 2020, when I am buying a Sequential Prophet X and will be busy with that new synth for a bit and will have a fresh outer box to ship it in.

UPDATE: I did send it, it’s back and better than ever

The Quantum 2.0 firmware beta

What happens in the beta stays in the beta. I will say this though, the current 2.0 beta 9 firmware is more stable and polished than the the non-beta 1.3.0 firmware release. Don’t be shy or paranoid, get the beta, you won’t regret it!

The Waldorf Quantum factory patches

Like most Quantum owners I would imagine, I didn’t buy the Quantum to use presets primarily. I bought it for sound design so I didn’t really spend much time cruising the presets. After 5 months, I did start checking out the presets in more detail. I was pleasantly surprised, there are some amazing presets. Like all synths, some are basic and they could be expanded. There is more than meets the eyes initially though.
