First, this notice is for the simple oscillator MiniKorg 700, not the 700s as suggested by the image above.

So we have this little monophonic synth.
Very simple configuration, rather than anything unusual:
-A low-pass filter and a high pass (called "traveler");
-An envelope generator with controls rather unusual "slow" and "singing" which act respectively attack and decay time (it becomes a fashion sustain if the release is activated);
A single-oscillator with different waveforms including two choruses of varying intensity. No PWM;
A switch-apply just the envelope on the filter called "Expand";
-A switch that activates the emphasis filter (resonance) called "Bright";
The Sustain-which changes the action of decay of the envelope and release, pradoxalement, cancels the real sustain;
-A "Bender" which creates a "rubber" playing on the pitch of the oscillator during the attack;
-Repeat with variable speed;
-Vibrato with speed control and intensity;
Delay-Vib.: Vibrato with delay;
-Portamento: classical time control.
It's been quite the ride. No preset, noon, CV / Gate or anything resembling modern features. No LFO, a shame.

UTILIZATION

Configuration is very simple.
Once you get used to the controls that are a bit unusual, it becomes extremely easy to edit the sounds. Within seconds, we just spend a large percussive bass has a slight lead and singing.

All controls are located under the keyboard, making them accessible and easy to change as you play on the other hand.
Not found the classic wheels of pitch and mod, so, having all the controls literally on hand makes sense: We modify the sound in real time while you play. I speak especially of the famous "Traveller" and envelope controls that add a lot of expressiveness in the game

I like the feel of the keyboard: soft and quick, if somewhat noisy, but ideal for the lead.

SOUNDS

The MiniKorg has only one oscillator, but what oscillator! It is perhaps not very stable, but it sounds very round, warm and fat. Above all, it sounds old! Pass in a Roland Re-201 and you immediately get the sound of 70s.
To the filter when it is simply phenomenal. The slope of the low-pass cutoff is not very steep for even being closed up, the sound is still very rich in medium frequency. This is by opening it you realize how powerful is the oscillator. Snap the resonance and the filter will bring out a lot of juicy harmonics at will.
The high-pass filter is used not only to cushion a bit low (which are huge) but also many highlight the richness of the harmonic oscillator.
As I mentioned above, the expression is very good, from the moment you start to happen smoothly and pitch modulation and use the other controls.

This synth is great for creating low until hot and juicy techno sounds rough and abrasive. The lead sounds are really cool too. Unfortunately, there is no real modulation possibilities, so forget synthesized sounds complex, it still sounds really low / hot lead of 70 years.

OVERALL OPINION

Overall, I love MiniKorg.
The sound is so hot and vintage, despite the lack of possibility of modulation, it is irreplaceable and incomparable among all my other synths.

I bought it used about a year ago. I paid $ 50 (about 41 euros) and given the odds that this synth has those days, I really did a very good deal, I never regret my choice.
