Sequential DSI Pro 2 gets all new wood ends + front strip

A great support experience and better than new wood

One day I was being lazy, and I leaned my bicycle up against my synths and wouldn’t you know it, somehow I scratched the front strip of my beloved Sequential DSI Pro 2 synthesizer. Yeah, I know it was a fairly insignificant scratch but it just bugged me, so I decided to order replacement parts from Sequential. I ordered the end pieces too, just to be sure the wood stain/finish all matched since I was already going full on OCD, ha! I’m glad I did too, because the replacements looked a lot better than the originals. Darker and a little more sheen to them. Anyhoo, it was a great support experience from Mark Kono at Sequential Support. $75 total including freight for the left+right end pieces and the front strip (including Pro 2 badge) and now, better than new.

The wood ends are a snap to replace, but the front strip is a tad more complicated – fortunately Mark gave me instructions, which follows these images of my parts replacement:

Sequential instructions:

You’ll need to remove the keybed as there are screws holding the front wood strip from the bottom of the keyboard as well as from the inside (you’ll see them under the lip of the front once the keybed is removed).

Removing and/or replacing the keybed on the Pro 2 is a relatively simple process involving nothing more than a screwdriver. Here are instructions for replacing the keybed:

To start, unplug all power/audio/MIDI/USB cables.

  1. Unscrew the two screws in each of the wooden sides.
  2. Once the wooden sides are removed, 3 additional screws on the left and 2 additional screws on the right side will be revealed. Remove these as well.
  3. Next, lay down some padding like a towel or a pillow and flip the Pro 2 over. Remove the 2 black screws to the right of the left front rubber foot. They are smaller than the other black screws, they have no flanges, and will be slightly lower than the foot, not directly inline.
  4. Flip the Pro 2 back over and with it facing you place your hands on the sides, on top half of the metalwork, and lift up and away from you. The lid will hinge open and stay open resting on the attached lanyard. You will be looking at the main board in the tray above the keybed.
  5. Remove the 2-wire aftertouch connector from the main board, it is located in the lower left corner. Pull straight up on the connector, DO NOT pull the wires themselves.
  6. Remove the keybed’s ribbon connector, it is located in the lower right of the main board. There are locking tabs holding the ribbon cable in but they are easily opened by prying the tabs away from each other in a horizontal motion with your thumbs or fingers; the cable will just pop out. Only medium force is required.
    • When reinstalling the ribbon with the tabs open, just push the connector straight down and the tabs will close behind it. Push the tabs together to make sure the cable is firmly seated.
  7. With the two connectors detached, close the lid and flip the unit over, face down, and rest the keys on a soft surface.
  8. Remove the 10 screws holding the keybed in from the bottom of the Pro 2. The screws are aligned in 2 horizontal rows of 5 black screws each, located just above the lower rubber feet. The keybed is now detached. Hold the keybed in place and flip the unit back over. The keybed can now be removed.
  9. Reassemble the Pro 2 in the reverse order.

IMPORTANT: The keybed standoffs are plastic. To avoid over-tightening and stripping standoffs when installing the keybed, DO NOT use an electric or powered screwdriver.

Latest Behringer RD-8 Drum Machine Shipping News

The Behringer carrot and stick continues

1st UPDATE: 8/9/2019 – This post
2nd UPDATE: 8/9/2019 – Behringer now says European retailer Thomann is air-freighting in first batch of RD-8s and should be on their site soon. See new photos.
3rd UPDATE: 8/16/2019 – Widely available for preorder including at my fav – Sweetwater. Thomann site says “In stock within 6-7 weeks”.

Back in the middle of May, Behringer said the RD-8 would be shipping by the end of May and at retailers 6-8 weeks later. In other words by the end of last month, July. Didn’t work out that way. Little surprise since no retailers were allowing preorders. Preorders are the first level of confirmation in my book.

Yesterday, 808 Day, they said “The w8 is over” and released 2 photos, slightly cropped versions of which you see here.

We shall see. I’ll believe it when I see it on Sweetwater.

Some first month thoughts about Waldorf Quantum

Crazy wild about my Waldorf Quantum

I have to say it. I wouldn’t promote the concept or seek it on purpose, but if I had to have only one synthesizer, the Waldorf Quantum might be the one to have.

After a few hiccups and an exchanged unit (First 48 hours – Waldorf Quantum joins “Studio” ha!) the second Quantum has been near flawless. I say near flawless, this however is what I expected.

OK, one super small thing. This morning, I was thinking about how much I like the layout of the Quantum, except for how dark it is around the Selection Dial. See the bottom center of the image above, the Selection Dial is between Save and Prev. You know it is there, even in the darkness. It’s funny how blind I can be, at the same time I was pondering this, I noticed an LED beneath the dial. Unlit. I couldn’t find a setting to turn it on, or documentation about it. On the Facebook Waldorf Quantum Synthesizer Group, it was thought the LED would stay off in OS v1.3.0 and earlier, but could be fixed in a newer firmware release. Weird. I was hoping it was an obscure setting. Oh well, no big deal though it does seem strange that a non-functional LED in the machine would be missed in quality inspection number one, even though I missed it for a month as well. Other than that, the hardware is designed well and works great.

So back to the beginning, my Quantum came with OS v1.2.3. I didn’t spend a lot of time experiencing that version. After making sure everything was basically functional I upgraded the system to OS v1.3.0. This process was easy and quick. Like everyone, I anxiously await OS v2.0, currently in beta. OS v1.3.0 is as I expected, buggy and unstable at times. Again, this is what I expected and not a problem, but I do want OS v2.0, ha! I’m in information technology and I can tell you that a lot of software runs properly when it is run correctly, but when people push the wrong buttons or don’t know what they are doing is where the cracks in the system show up the most. So I probably put the Quantum through its worst tests and I have managed to crash it or make a reboot necessary a few times.

So there you have it, the unexpected bad and the expected bad. Beyond that, all I can say is WOW!

The integrated panel and screen are state of the art

This machine has redefined what I want in a synthesizer. It lives up to the hype. The Quantum is beyond flash if you ask me.

The panel layout is great, lots of knobs with LEDs that may change color, depending on the function of the moment. These colors are custom selectable but in stock configuration, as an example in the Oscillator section, the Wavetable LEDs are teal, the Waveform LEDs are green, the Particle LEDs are blue, and the Resonator LEDs are red. This can be a huge help to know what state you are in at a glance.

I am a big fan of the Sequential/DSI knob and screen combinations on synths like the Pro 2, Prophet 12, and Prophet X/XL. However with its touch screen, the Waldorf Quantum takes screen control to new heights. The visual representations of the LFOs, oscillators, filters, envelopes, mod matrix, and effects are cutting edge. Like the Sequential/DSI adjusting any knob brings up the related area on the screen display. On the screen there are 6 more knobs to fine tune various parameters, 16 buttons to jump to major screens, and the Dial Selection knob to scroll and select with. This is flat folks, there is no sensation of menu diving.

Not only all that, but this screen is a touch screen, you can select even more with your finger. You can even draw things like waveforms, envelopes, and in the example image at the top of this post, sequencer notes.

The digital oscillators

I’m biased towards digital-analog hybrid synths. I have and have had some analog oscillator synths like Korg, Moog and Novation, and they no doubt have certain analog-y sounds, characteristics and charms to them, but I’m still preferenced to digital oscillators like the Sequential/DSI Pro 2, Prophet 12, and Prophet X/XL synths.

That said, the Quantum in its wide open, out the door state, is a little more digital-y than those synths. You are going to notice that digital sound, in some cases metallic or windy. This is not to say you can’t analog and warm it up, you can. I think most Quantum demo videos don’t really show that well, so know you can.

Speaking of videos, the Uptown Oscillators Waldorf Quantum Page has over 120 Quantum curated videos in 2 YouTube lists, which are good and useful. There are no complete and comprehensive tutorial video sets for the Quantum to my knowledge out there, however. An example of what I mean by complete and comprehensive would be like Marc Doty’s Automatic Gainsay The Dave Smith Instruments Pro 2 YouTube List, a 15 video collection. Hopefully someday Waldorf will produce or underwrite something like this for the Quantum.

Back to the digital oscillators, there are 3 of them, and a choice of 4 synthesis engines – Waldorf-style Wavetables, Classic Waveforms, Granular Sampler, Resonator and soon with OS 2.0, a 5th – Kernel synthesis.

You could write a large book chapter and several videos minimum about each one of these synthesis engines. There is so much functionality and choice in the Quantum oscillators, that you could have no other functions or controls and still have your hands full.

Well, that’s it for now. If you are interested in the Waldorf Quantum, be sure to check back for more. The Quantum will be a major focus of mine for years to come, I’m sure.

Waldorf Quantum joins “Studio” ha!

My Atmospheric and Noise Quotients Just Went Way Up

Yeah, I know… buying the synths has (so far) really overshadowed properly mounting the synths. That day will come though. It has to. Living in a Jesus commune means I’m just a little shy on self-fulfillment space. Now if I want to have a auditorium concert, there are multiple options that I wrote about in a previous post A Musician Supportive Sober Home, however, my private studio space is very limited. Still I’m gonna imagine many bedroom producers have issues even worse than mine, so I’ll thank G-d for such a wonderful problem and move on.

A problem I have with saving up for a piece of reasonably expensive gear, is I have time to way overthink the choice of gear. Saving my coins for nearly a year total, I agonized between buying the Waldorf Quantum or the Sequential Prophet X first. Being more of an information technology kind of synthesist than a talented keyboard player, the sound design functions of the Quantum won out in the end. I still intend to get a Prophet X next year, unless something better presents itself.

2 Resonator buttons on OSC3 instead of Particle and Resonator

OK, on to the Waldorf Quantum itself! The first thing I noticed after removing it from triple boxed packaging and firing it up, was that the 4th C key did not work. On a whim, I upgraded the OS to v1.3 from the v1.23 it came with. This was very easy to do, but there was no change. My reseller’s tech support confirmed they would replace the unit, so I’m waiting on a new one. I also noticed a Particle Oscillator button on OSC3 was named Resonator, another must return item. Tech support said defective returns on the Quantum are around 1% which is normal for electronics from my computer experience. Still, I think these 2 flaws are quality control gone a bit sloppy. In the meantime I get to play with a mostly functional synth until the replacement arrives.

So with 48 hours experience, I am still semi-lost on the machine but I can see the coolness of this synth matches the hype. As I mentioned above the OS is very easy to upgrade. With the SD card, I think it was a bit easier and faster than most USB type OS upgrades. Like everyone else, I anxiously await the OS 2.0 release. I’m not sure what to think yet about the 2.0 beta program.

This synth is built. It’s 40 lbs. folks, def not a lap synth. The Quantum Fatar keyboard is more similar to my Moog Subsequent 37 than my Sequential Pro 2, a little more solid feel of the three higher end keyboards I have. The Pro 2 feels lighter, faster with more of that ‘plink’. The Subsequent has more ‘plunk’ and the Quantum even a little more so. How’s that for scientific description?

Now I would expect no one would buy a synthesizer like the Quantum to use presets primarily. Still for $4k+ I think the preset collection should be world class. There are some good presets on the Quantum, but I do think they should keep working on this and release updated presets periodically.

Anyhoo, that’s all I have to say for first look at the Waldorf Quantum. I’m sure I’ll be posting more soon, as well as updating the Uptown Oscillators Waldorf Quantum page.


July 2, 2019 Update: Two business days later, Sweetwater had a replacement Quantum delivered which appears to be in very good order.
July 8, 2019 Update: The replacement Quantum has been rock solid and the impressive machine I expected.

Added Moog Grandmother + One to Synth Gear Section

The Moog Grandmother – as always, will update videos and info as becomes available:

The Moog One – as always, will update videos and info as becomes available:

The Grandmother, Moog’s entry level keyboard semi-modular has proven to be quite popular, As I write this, currently #3 on Sweetwater’s most popular synthesizer list. The One, Moog’s polyphonic flagship, of course is more of a quality not quantity item due to its features and price.
