My mate played a Delta for years, He was renowned for employing both hands on the keyboard and moving the joystck with his Nose !! ... Forty odd years on and we still have a laugh about Nosing the Delta ... 👃

He nose what he's doing.

I used to use that trick, in at least two bands I was in! Great way to get a pitch bend with no hands free. If you buy a keyboard from a keyboard player, always wipe the pitch bend control with disinfectant. :D

I played one of these in 1987 when they were really out of vogue. Great demo tunes but I really like that little 15/8 diddy in the middle. Cheers.

The Sigma began life out of vogue and then ran with it! 15/8 is a fitting time signature for such an oddball synth. Cheers!

[@KlodFather]

@@AlexBallMusic - I am certain that I heard this thing in some of those early 80's new wave punk synth bands... love those old synths. Someone should map out the sounds so they can be run in the new Midi/USB boards generically available today. What a treasure.

[@MFitz12]

After Rick Wakeman got sponsored by Korg, he left all his Minimoog's at home and used 2 of these for solos and melody lines in his live performances instead.

[@DaveG207]

Somehow it felt like the quirkiest synth to date. And I loved it!

It's what I've loved about Korg, they've made some odd ball synths over the years but that's what makes them unique. Great demo as usual.

[@AlexBallMusic]

Yep, probably my favourite thing about Korg.

[@HeavyDutyModularSynths]

its true, they are innovative, but, usually when ive gotten their gear, im dissapointed at the end of the day. But, ive only bought the oddball stuff, never a full size keyboard, bigger synth or something.... almost was going to get one of those new touch capacitance keyboards i think microkorg. because id like a synth that does synthesizer sounds of its own, that has CV output at the same time. since i own a modular. i thought that would be pretty cool. but i heard of some problems with the touch keys on that thing.

This odd synth demands odd time.

[@DominikMerscheid]

Guten Tag, tolles Video! The Sigma was my first analog monophonic synthesizer in 2005 and I used it very often as a performance synthesizer for the live gigs of my retro progressive rock band. His big advantages are this cool ring modulator and that you can combine all (!) of the presets. But the overall sound is rather metallic and thin compared to the Roland SH-2000 which has very similar performance features and presets plus a warmer, minimoog-like sound. Keep up your extraordinary videos!!

[@AlexBallMusic]

Yeah, quite a klanger this one! But it can be quite beefy at times. Hopefully I'll try the SH-2000 at some point. It has the Moog infringing filter in it, so that explains it!

"Rick Wakeman played one." Rick Wakeman played everything. What a fascinatingly weird little beast. I love the cutoff filter joystick. I bet it was used for effects and scoring in many 70s sci-fi movie soundtracks. Or maybe Turkish knockoff 70s sci-fi movie soundtracks. This is outstanding. Every time I think I've seen and heard and played 'em all, Alex, you pull another obscure machine out of retirement.

[@AlexBallMusic]

Yeah, Wakeman did a Reverb shop last year and he did have bloomin' everything. There was a Sigma in there. Goodness only knows what (if anything) the Sigma was used on. Quite possibly the Turkish sci-fi machine!

[@Piktor201]

Wow! That was a nice journey back to my youth. I grew up in a small town with a small music gear shop. It offered a collection of the most requested instruments in such villages. In case of synths there were in fact just three of them: a Korg MS-20, something from Crumar which I don't remember exactly and - of course - one Korg Sigma. The owner of the shop had no clue of these instruments but he allowed me sometimes to explore them and the Sigma was truly my favourite. However I could'n afford it these days since I was young and still saving money for my bike. Great to see that the Sigma is not completely forgotten and that there's at least one still operational. By the way: on my Mac I have also the Fullbucket Stigma installed which is a (VST/AU) simulating the KORG Sigma. Thank you for the video.

[@AlexBallMusic]

The most requested instruments were the MS-20, Sigma and a Crumar! Well, well, well. What was the most popular local music?

[@oliverkreuzahler6444]

In fact I don't think that synths in general had anything to do with the mainstream music in this town. This shop mainly sold acoustic guitars, brass instruments, entertainer organs and so on for tradional folky stuff. The owner surely just offered these synths to complete his portfolio and I assume he choose them just because of their pricing against brands like Moog, ARP etc. Another small anecdote: the MS-20 came accomplished by an SQ-10 but the shop owner was newer able to get it to work because "this thing was for professionals only". 😄

[@macronencer]

I'd forgotten this thing ever existed. Thank you! Not actually heard it demonstrated before... of all the weird old synths I've seen on KZbin, I think this has one of the most characteristic sounds. Amazing! And that ring mod does *sound* like cross mod to me, but I'm no engineer, so don't take my word for it. As a microtonal-curious student of the weird, the quarter tone thing really excited me at first. It's a shame it only works after you hold down an initial key though - but I think the brass trills were an excellent way to use it.

[@AlexBallMusic]

Quite the oddball isn't it! The "ring mod" is not quite a full ring mod, others have explained in the comments after looking at the schematic. I'll have to dig back for the explanation as I've already forgotten. Quarter tone - I wonder if it only works that way due to some trick in the keybed, like the ARP duophony thing. Does seem an odd way to implement it, so I wonder if they stumbled across it and made it a feature.

Man, Alex.... watching your videos is either inspiring or demoralizing. On the one hand, I aspire to create as incredible material as you do, yet on the other hand, I don't see that ever happening lol. You do what I'd love to do - acquire vintage synths, make fantastic videos with them featuring the music you made on them. I don't know how you can afford them, or what your primary means of income is that allows you to do stuff like this, but that's also none of my business. Still, you make even the cheesiest divide-down Korgs sound fresh and modern without even the slightest hint of old. I always end up with very old, vintage style sounds, even when I'm trying for modernity. I always enjoy your videos!

Cheers Adam. You're very modest btw, my playing is pretty Mickey Mouse compared to yours. To answer your question, I don't own many of the synths that I feature. They're just passing through.

[@AlexBallMusic]

[@arkiteuthis3747]

Hey another tech thing to explain! The 'ring mod' on the Sigma is not a true FQM (four quadrant multiplier), but to call it cross mod is also incomplete IMHO. It's an amplitude modulator that takes the two synth signals as carrier and modulator inputs, based on a single JFET which is used as an attenuator, and the output voltage Vout is proportional to Vcarr(Vmod) for Vmod > 0, and Vout = 0 when Vmod < 0. This is then summed with the original carrier signal, so that when the modulator voltage is low, the output is equal to the inverse of the carrier signal, or Vout ≈ -Vcarr, and when the modulator voltage is high, the output of the JFET is effectively cancelled out, so Vout ≈ Vcarr. We can see that this makes the output swing high when both signals are positive or negative (i.e. have the same polarity), and swings low when they are differing in polarity. Thus, we get Vout ≈ Vcarr(Vmod) across all four quadrants, so we have a FQM in theory. In practice, though, the solution gives clunky results that are very sensitive to changes in input amplitude and polarity, so it falls short of what I would call a true FQM. As to whether or not it's a cross mod, well I guess it is, but by that definition, ring mod is also a type of cross mod, so idk... Still, I've seen worse from Korg, and it's still an awesome circuit. I know this one was heavy, but there's no easy way to explain the electronics of ring modulators. Nevertheless, I hope it provides some clarity as to what you're hearing. If not, I'd be willing to make a video on ring mod in general to explain it in more detail. Thanks, and have a wonderful day!

@@AlexBallMusic Yes, Human League used several Korg synths back then, they have others like the 770 and the MS-20. Mainly, Human League in their beginings used Japanese synths and sequencers, Korg, Roland, Yamaha and Casio, the only thing American was the Linn LM-1 in the Dare album. Cheers!

When I first got my Korg DW-8000, the first sound, I twiddled it’s joystick and knew it was a keeper!

[@AlexBallMusic]

Hopefully I'll try one of those at some point.

Or was it schticky schticky poon tang?

[@chrishopkins209]

Didn’t you also use it on the soundtrack to “Analize This” Geert?

[@sounddoctorin]

love the greek korgs! /sigma has 13 korg 35 vcf's i recall...one for synthe...12 in inst. section allowing for mass layering. i had several issues on mine...worked good since til something recent where i can't full sweep inst. from synthe...

[@AlexBallMusic]

Yeah, it is 12 or 13 Korg35 filters. I think eight are in the synthe section as that's what the demonstration record says, but I'm not a tech and I haven't looked inside. That could be wrong. Hope you manage to fix yours!

[@sounddoctorin]

i don't know why i'd never confirmed that in schemo. indeed 8 independent 35's in synthe each w/joystick control for lp, and just over all hpf via ldr in op amp filter....and vco's use dividers/proportioning to approx saw wave it appears like in DS2

[@AlexBallMusic]

@@sounddoctorin Thanks for checking. So it's divide down / wave shaping? Rather than individual VCOs? Are there just two VCOs in that case? One for Synthe and one for Instrument?

[@EspenKraft]

Late to the party as usual, but thanks for yet another cool demo Alex! I have a friend that consider this synth a must for his sound. To me, it's charming but not enough to make me want one, just like an old uncle of mine. He smells weird, and although he's friendly and inviting, I don't visit very often.... Cheers!

[@AlexBallMusic]

Hey Espen. Yep, quite the oddball. Some really cool sounds in there though, which is suprising considering that it looks like a bit of furniture.

[@SpikesStudio3]

Thanks alex. Pretty happy you are doing odd synths. There are a ton out there for you to do. Getting tired of jupiter demos et al.

[@AlexBallMusic]

Thanks Michael, glad to be able to supply the weirdess. Although, a couple of Jupiters are actually lined up for videos. 😬

[@nstanifer28]

fantastic sounds!

[@TROGULAR10000]

That last jam is insane!

[@AlexBallMusic]

Cheers!
