I love this synth, it's fat, versatile and unique. I discovered a new preset bank that I think really makes this vintage synth shine!
Let's Upgrade a Korg DSS-1
Переглядів 3 тис.3 місяці тому
The Korg DSS-1 is actually one of the most incredibly synth/sampler combos that Korg ever released in the 1980's. This incredibly underrated powerhouse can be bought for very little, and yet I'm here to say that you should grab one if you can because this machine sounds PHAT!!! Many thanks to Straylight Engineering for a comprehensive tutorial on how to replace the display. Go to straylightengi...

KORG DW-6000 : The Jam
Переглядів 1,9 тис.10 місяців тому
Personally I think that the Korg DW-6000 is one of the most underrated synths from the mid-80s, largely due to the fact that the Korg factory presets are absolute garbage. Here is a set created by AnalogAudio1 which really bring this synth to life. Just added a small amount of hall reverb, otherwise what you hear on the video is exactly what came out of the DW-6000. Stay tuned for the repair vi...
I have an ax-60. And an S-612. I want an ax-80 also but don’t have one yet probably next year. I replaced all the red Leds and the red display with blue leds and a blue display cause blue is cool and it looks so good now.
Bravo!
This is very very cool!
Someday, i hope to aquire an AX80. Atleast i have a rackmount akai synth... :)
At 29:24 I’m assuming that you are using your multimeter, on continuity mode, right? Please let me know. Also, awesome video! I like your calm approach to diagnosing this synth. I’m trying to fix a Korg Poly-800, I’m at the “downloading the preset audio file” stage but my synth isn’t having it… Anyhoo, I’m now subscribed to your channel, as I believe I can learn a lot from your videos. I’m happy that you got this beauty up and running again, kudos! Great video. Cheers!
Yeah, I'm using it in continuity, but honestly it's tricky to diagnose a voltage regulator this way. Best way is to check to see what voltage is being output, and even then it can be misleading when there is no load on the circuit.
I have a Matrix 1000 that someone butchered installing the Kiwi upgrade. Lifted traces everywhere. It's an ongoing project.
I have to say that after working on these machines I try not to judge too much previous work (although sometimes it's difficult not to). But the reality is that people try their best to fix these synths, and sometimes they get themselves in trouble as I have in the past!
Ah, taking those keys off is a pain. I broke a few trying to fix the key bed felt.
Yup....be careful. They're expensive to replace!
16:48 sounds like the intro to Origin Unknown - Valley of the Shadows. I know they used a Korg Mono Poly for that, but maybe the patch for this one isn’t too far off either!
Congratulations! What a display of skill and determination. Enjoy the Matrix 6. I still have the one that I bought in 1986. Unfortunately, most of the segments on the display are shot, half the after touch is none functioning and one of the six voices seems to trigger the filter envelope at full velocity no matter how lightly I play. Checked online for parts and at this point, it looks like replacement parts will be difficult, if not impossible, to find. I may have someone look under the hood anyway, to see if fixes are not as complicated as I think. I am not going to be happy parking it in the landfill.
I love it...perhaps my favorite synth right now. I'm hoping eventually to get my hands on an Xpander, but until then this is the closest that I can afford!
Great video. I have owned both the DW-6000 and the 8000. I sold the 8000 but kept the 6000. It always seemed to have more punch. Maybe that was because of the the velocity sensitivity on the 8000, I don’t know. Nonetheless, the 6000 has the most wicked filters on any synth that I have owned. Thanks.
i can get a DW8000 for a low price but the arpegiator doesn't work anymore. Do you think it's a big deal to repair it ?
Hard to say...could be something really simple like the arpeggiator switch is dirty, to something more complicated to diagnose. Question is - how important is a working arpeggiator to you?
@@kayslabs yes not as much but i saw your 2 demos about the DW8000 and the DW6000 and i prefer the sound of the DW6000. Does the 2 ones sound différent or is cause of the démo and the presets you choosed ? In fact i saw 2 announcements for a DW6000 and an DW8000 at the same price. The DW8000 looks clean but with the arpegiator no longer work and a DW6000 looks dirty but fonctionnal.
@@labelle4185 I am thinking about doing some comparisons videos at some point and that was going to be one of the videos (DW6000 vs DW8000). It's hard to put it into words, but what I would say is that the DW6000 sounds grittier and more "rude" whereas the DW8000 is a bit more refined and gentler. In very simplistic terms, I would say that the DW6000 can excel at synth bass lines and leads that need to cut through a mix. The DW8000 can excel at pads and more complex synth instruments.
@@kayslabs ok so you answer my question. I wanted to know if the DW8000 was exactly the same with just more options. But finally not. Im hearing too (on your démos) that the sound of the DW6000 is really near to an analog synth, warm and dirty. And i didn't heard this on your demo with the DW8000. I heard a synth more proper and sounds more like a new school synth cold an without the soul i heard with the DW6000 (and less fat). So now i know it was not just on my imagination.
do the sound of the DW 8000 is the same as the DW 6000 ? i was very seducted by your demo on the DW 6000 but less for this one.
how lucky you are to know how to restore and upgrade all that old synths
My favorite synth of all time! I can sit at mine and do sound design for hours without even noticing how much time has gone by. Love it!
I've got one myself for about 40 years and indeed, it needs a lot of editing. Well done!
You are connecting high voltage for the old backlight to the LED! It can damage the LED! Just add 2 wires from pin 1 to pin 16 and pin 2 to pin 15 so the LED backlight gets 5 volts. Series resistors are already on the PCB. Remove the old backlight wires.
I'd be running an oled from the gotek onto the top, since it's the main mod that will unlock practically unlimited storage
To answer your question about the jumper, it's due to one of the final board revisions. This surprises me a bit because the white ones were the final batch. It should have had the latest board revision which didn't require the jumper wire. These were manufactured by Gibson after they bought Oberheim. They may have thrown an old board in, or it may have been transplanted from a black one.
Enjoying your vids, but man, you really need a quality solder vacuum. A Hakko is a game changer. It will significantly reduce your stress level removing components
Hakko 808 is Great !
I also have a DSS1, we should do a duet on them!
You should do a Juno 106 and Kurz 2000 AND a Yamaha DX21 refurb video. I might know someone……
Nice presets, unfortunately the link didn't work for downloading patches, can you make it work?
What are LED sliders? Nevermind you answered it right after I asked. But what's even better is putting clear rubber caps over the LED sliders.
nice idea, where do you find those?
The parts you want to look for are "Key Bushings"
Wish I still had mine! Great video!
Great vid! For those who are looking for the entire factory library (including the catalogue) just copy paste this into google search: Korg DSS-1 Factory Library for Gotek Flash Floppy HxC owners
As a Gen xer, although I've never owned this sampler, it was reasonably well known about, at least back in the 90s. It was definitely a sales flop, being expensive, not an Akai, physically massive etc. But these were great sounding machines, no doubt. The Roland S-50/S-550/S-330 are from around the same time. I owned a Roland S-330, great sounding, lofi, crunch and warm, all in a 1RU format!
If you do a lot of work on keys like those, look into some dental tools. They're great for getting in tight places and scraping gunk off old contacts.
@18:00 You're calling the connections "bottom" and "top" in relation to the camera (and you), when the text on the board is upside down. That might confuse some people.
nice!
You can add Lorn to the list of notable users!
It shares much of the same dna with the DW8000. Not sure if the filters was the same but they kinda used the same tech making the Wavetables for the DW8000. One funny thing is some of the sample disks from the DSS-1 is converted from 12 bit to the 16bit format of the M-1 and T-series, hence some people bashed the M1 somewhat because not all samples was "true" 16bits but its also some of those gritty sounds that gave the M1 some character even it was fully 16bit digital. The DW was a great hybrid Synth btw. I kinda wish if Korg ever will make a new showstopper Synth to replace the KRONOS, that they would re-introduce a true Analog filter section. I remember the DWG Wavetables never sounded as good in the M1/T3 nor in the Kronos. That Analog filtering is what makes the difference.
I had a DW6000 and absolutely loved it. I also had a Roland Juno 6 but felt it was a one trick pony, everything had that same sound. The DW 6000 really is a true underrated synth. Loved it!
Love these videos on those old synths from mid 80s, I remember this when it was new as 1986 was my into to the synth world and all the magazines like SOS and E&MM at the time... there was basically this, the Sequential Prophet 2002, the Roland S50 and the Mirage as well as the Akai S series which was becoming more and more prominent. It was big technical evolution because us normal guys could just about afford these keyboards as opposed to the previous generation of Emu/Kurzweil samplers... Adding those Gotek drives and have access to libraries sounds like a great idea.
Yo! This one evaded my attempts to uncover all the looked-over , disregarded synths w analog filters after I got the jx-8p which like dss1 looks like total snoozefest of early digital crap. Now everyone has realized this about the jx8p, I wonder if DSS-1 can possibly be found at non inflated prices…?!
You can find it, depends on where you live. I for one am selling one of mine since I don't really need two of them. The main issue is the shipping charges since this thing is big and heavy!
Perfect timing. I started upgrading my DSS-1 this week! Many thanks.
I've got one and i love it. It's my dream to have an usb substitute for the floppy, but i'm asking how can i transfer the original floppy disks to the usb key, for i don't know if they're compatible with Windows system, to copy them through a PC
Good question. Either you would need a floppy drive for your PC and then use one of the many apps to convert it to a disk image that is compatible with the Gotten USB format, or find a way to transfer the DSS-1 presets into your PC with a librarian type of app. Either way it's a bit of a challenge for sure. Try the Facebook Korg DSS-1 forum, it's been quite helpful in the past.
Thank you
You can use the free OmniFlop software to rip your floppies as .dsk files using a cheap PC USB floppy drive, then you use the also free 'Korg DSS-1 CopyQM DSK to IMG and HFE v0.1' software to convert these files into compatible files for use in a USB drive like the Gotek.
What are the remaining components on the EL backlight inverter board for? You went from EL to LED backlight which only requires DC voltage.
Not sure, I just followed the Starlight Engineering info.
Just a thought, Regarding the scratches. Can you get a grey coloured Sharpie to touch them up? Even if it is the wrong shade of grey, it might make them less noticable. PS: I got a pack of coloured Sharpies off of eBay, they are quite cheap, so no real loss if it does not work.
Definitely going to get a Gotek for my DSS-1
Watched the whole thing bro. Am never going to get a dss1. BUT, I do have an eps16+ And they are not that far apart. Every few years, i have to strip the keybed for a good clean. (It doesnt get used much) i am trying to find a way to get my library off my syquest 135 scsi to put on thumb drive so i dont lose 30 years of samples. 😓🤔 Any tips? 🇦🇺🍻👍
Check out ChickenSys (dot you know the rest). Garth is incredibly knowledgeable and helpful, and I believe has a SCSI to USB adapter.
@@kayslabs will do. Cheers. 👍👍👍
Nice work! But what about the jumpers on the Gotek, did you need to set them in a particular way for this machine? (I've a mixed experience with theses Goteks, on a Yamaha SU700 it was perfectly fine but I've never achieved to make this to work in a Akai S1100)
I didn't have to move the jumpers, I think the standard configuration should work for most machines.
I had a chance to use one at church. Great keyboard.
Nice. Can you post the sysex file somewhere for others? Thank you.
I have a DW-8000 with the opposite problem. My main output jack doesn't work, but my headphone output is fine. Do you think the op amp that you replace also has something to do with the main out as well, or is there perhaps another separate op amp the main out?
Good question. When I was looking over the circuit board that deals with the front panel volume control, the op-amp that I replaced was the only one that I saw on that board. I am not sure if that opamp controls both the headphone, and the main outputs, in which case replacing it would address both. When you say that your main out doesn't work, what does that mean exactly?
@@kayslabs I get no audio at all out of the main outputs. No crackling or intermittent signal, just silence. But i can get audio from the headphone output.
@@dessiplaer Then I don't think the opamp is at fault. Could be a broken trace, or some wire that is not making the connection between the VCA and the output. Have you checked the plugs PCB, to make sure that you don't have some broken solder somewhere in there?
@@kayslabs Thanks for the info. I'll have to do some digging.
If I may give you an advice, DON'T put circuit boards over your keyboards (panel and keys), watching your previous videos I noticed that you tend to do that. As you already know PCBs are full of pointy solder joints on the bottom, where the components' pins are, one bad move and you would end scratching your precious instrument. And if the device is not yours but one you're repairing for another person, that's gonna be a very, very big problem. If you have to do that, put something like old newspapers underneath the PCB so that it doesn't touch the surface you're putting it on, and you're good to go. Preferreably don't use plasticky things like bags, bubblewrap, etc as plastics often tend to build electrostatic charges which are bad for ICs.
Thank you, good to know!
@@kayslabs You're welcome :-)
👍
I just bought that same oscilloscope to fix my juno 106 :) def worth it!
So good, I love the dw8000, im legit sitting next to it in the studio... Korg really should do another fullsize run of the dw8000, multi timbrality would have been really the only thing i would want added, along with sick surface controls obviously.
Subbed.
Wish I could give this 2 thumbs up. Love my DW8000
