Korg Sigma
Well we're not going to repeat what's already been listed just still say that its appearance with little synth button to bontempi gives it a kitsch side limit toy, everything is raised by the control panel that by its simplicity struck a balance in aesthetics of the machine


Very easy to use, it is intuitive, and once you have spotted the function and possilité each knob can even begin to fair that was in the head with a little curiosity and the first results are amazing!


It is fascinating because it is unique, and large space, frankly the fact that he is a force to be monophonic additional character, buy a sigma is a bargain when you love analog and creation that comes the path beaten, you do not play on the same register of sounds which were used to rub! We have some good greasy powerful bass and soaring lead short one goes through all the steps!


I use it ... TODAY! I spend the afternoon and evening it only helped the sigma 20 yamaha sk without effects, without pedals, what I like most is authenticity and the fact is that it is unadorned it pushes you to go further in your search for sounds, I do not regret my choice even if I count aquérir a Jupiter8 Roland and moog, I sincerely believe I have got hold of something that stands out, for 300 € c is correct, it's not more expensive would be worth the shot ... Finally I would say that in a few months!

Read the previous opinion which is very well detailed.
I will add just the camera is equipped with inputs and outputs for control or send information control:
FCM in VCF (-5V +5 V), VCO FM in (Oct / Volt-3V +3 V), Keyboard Trigger Out, out CV (Hz / Volt 0-8V), Eg Trigger in, CV in VCO (Hz / Volt 0 -8V). These functions are very interesting because with converters CV Gate / Midi can do so via a play midi sequencer and control some of its functions.

There is also along the back edge, behind rubber masks, 14 tiny knobs that can be ordered with a thin screwdriver. It can adjust the output currents of the CV gate, Trig ... and also to adjust the amplitude of the particular pitch.


So it's a very simple device to take control.
Control everything on the surface of the device.
I reproach him just that we can not save the settings.
For a synth of this caliber out in 79, it might be feasible.


The sounds are good and very typical and pre-amplification stage is serious
Opportunities to create and lead synth sounds too low electro are infinite.
The grain is there and the various presets sound good hot
Provide a good old analog delay to give him all his letters of nobility.

I just liked a wider spectrum a bit with very high acute especially when playing with cutoff filters (for example sequential circuit) and ultradeep more pronounced (just missing the synth).


I have the Korg Sigma last few days he took me to a spot of luxury in the middle of my other keyboards being the only analogue to this day. Paid 350 used I think it's expensive but ... When you want something rare often need more than what it really costs.
250 would have been a very good price. It is estimated the site vintagesynth.com 100 to $ 150 and there to blow it hurts to have paid 350 but it also runs ads where people are proposing between 400 and 600 euros (!!!).

I will soon invest in a controller Cv to exploit at best.
It is a beautiful object and it roars like love.

It's a monophonic synth with two oscillators, equipped with "push" switch to access a series of pre-selected sounds (presets), a bit like the ARP Pro Soloist. Hence the original pub presenting primarily as a stage synth, capable of a multitude of sound combinations.
In fact, these presets are arranged in two categories of sounds (since both oscillators): "synths" and "instruments", this last section is dedicated to the "imitation" of existing instruments: high wooden flute, string, bassoon, etc.. These two sections are of course mixable via a rotary control on the left of the keyboard, but you can also mix the presets of the same section of them (note: mono output or two mono for each oscillator separately).
A section called "effects" (but which are not really) can act on the octave, the LFO, multiple or single trigger (or not interesting to retrigger the envelope), playing quarter-tones or other (not really useful, because to do so you must press a note while playing on the other hand), grant (or Disagree) the oscilloscope them, and especially to adjust the sensitivity of the keyboard.
Yes, because the keyboard is pressure sensitive and can act on the LFO, pitch, filter ...
The keyboard is very sturdy, even a little "Lourdeaux" (it makes noise when playing!), But that's fine dexterity to work and make the chorus Emerson. In 20 years of use (yes!), I got very well, and I assure you that gains in precision, nothing to do with keyboards "plastoc" some Yamaha for example.
Oh, I forgot, there are two joysticks acting on the filter and modulation via LFO.
In summary, the Sigma was presented as a synthetic scene, and it is true that compared to my late MS 20, was immediately more useful for creating sounds: there are good combinations quickly to his taste will leave you more later (this is why I sold my MS 20 at the time, for the difficulty of use on stage)
In fact, I really think the Pro Soloist (in the design, not the sound) I have also, but with two oscillators (one against the Pro Soloist).


See above: mono analog synth practical, effective immediately


Ah, here we go:

I'm not objective because I'm in love with this synth! Probably in part because he accompanied me for many years of creating music "rock progressivesque", and still is a friendly and loyal companion, who worked wonders, and I do not separate myself even for a huge sum! So do not try to buy it from me, it just lost.

We're here in the presence of the typical Korg. That is, it has nothing to do with a Moog, Arp or not is something else, and that's what makes it so charming.

First we must insist on the extraordinary stability of oscillators: I who have seen a few analog synths (including the Moog), I've never seen anything like it. It is lighter, and after a few seconds, it's just, and it does not move! But if I remember correctly, the MS20 had also this advantage, to believe that the material Korg was particularly effective on it. As for temperament, it's miraculous accuracy over the entire keyboard, your electronic tuner would not return!

As for the (finally), it's great: the kind to be placed immediately in a mix, both in setting its "bold", mixed with two sections (and slightly désacordées), with its simple one solo, especially the "instrument".

In fact, there he is particularly brilliant in my humble opinion. Of course, do not the imitation of existing instruments with a synthetic analogue of the time! But it's much better actually, because the imitation will ever dream of an ordinary sample.

Thus, the flute (with its waveform simple but so warm), and especially the top timber (ah, the rectangular wave dash at will!), Are beautiful. A bit of reverb, vibrato set properly with the LFO, and it provided the thrill.

I know some might say it is far from a big sound of Minimoog, it's true actually, but who cares: it's something else I tell you! This synth a grain of its own which I am passionate about for many years, and I continue to use extensively because it is so unique that it's a little become my trademark, I proudly claim. What do you expect to synth except that it allows us to express a personal style, a "paw"?

This is what I have this little companion, I lovingly pampered!


No need to conclude, I think you understand me!

A clarification: I bought this synhé twice (yes, the first time I had to part with it to my great despair because of financial problems, and also that damned "air time" of 80 years for me posed as a nerdy eighter sixty - although I was only 15 years in 1980! - and swore by the DX7 and the Top 50!). I regretted this move just after having committed it, but luck was with me: the buyer had quickly sold (What a stupid monophonic at the dawn of the digital age), and I l 'I found by chance in a store of OCAS.

I bought for a pittance. So it was written that this synth would not leave me!
