Hartmann Neuron – demo

A video from the taylor12k youtube channel.
I’ve used the little vst version Neuron Nuke and I can say it’s an amazing synth…

Elektron Monomachine Sequencer

The Sequencer is one of the most interesting parts of the Monomachine as it can control anything on the machine.
The sequencer works as a realtime or step (Roland TR-like) mode , and it can be switched record on or off with the sequencer running.
That’s ideal for live performance!

Programming notes is easy, if a midi keyboard is connected it can record from midi in , but it can be programmed standalone using the step sequencer buttons as they act as keys.

After notes programming the most useful things is the PARAMETER LOCKS programming.
A parameter lock is a motion sequence of a parameter.
It can be done on a single step (using step programming) or it can be recorded realtime turnig the knobs while the sequencer is running in realtime recording.
This function enables to modify extremely every nuance of the sound in a very easy way , and It’an effective strenght of the Elektron philosophy.

Applied to to a digipro machine , for example, it can create programmed wavesequences…

Applied to an envelope can morph the shape of a sound, from percussive to sustained…

Applied to a efx can for example vary the delay time and feedback…

Every thing in the machine can be controlled by the sequencer and the intensive use of parameter locks can create sound sequences really complex and even really difficult to recreate with another instrument.

Korg MS-20 video introduction

Korg MS-20 review (Part-1)

Korg MS 20

The Korg MS-20 is one of the most famous vintage synths ever.
It stands up there with the Minimoog, ARP 2600, EMS Synthi, Jupiters, TB-303, etc.
When it was produced , Korg marketed it as a low cost “baby 2600” , it was the semimodular synth for the masses.
The look is somehow  inspired by the big Moog modulars, with the front panel that stads upright the keyboard, that is attached to the body, to be the most compact and portable, all in a typical japanese way.

The synth is divided into two parts : the left side , prepatched with the knobs and the right side , the patchable with the patchbay and external signal processor.

The synth has:

  • 2 VCO (with different waves)
  • VCO MIXER
  • 2 VCF (HPF and LPF 12 dB/oct, both resonant)
  • VCA
  • MODULATION GENERATOR (LFO)
  • 2 ENVELOPES

VCOs
The 2 VCOs have different settings capabilities and different functions.
VCO1 has:

WAVE SELECTOR:

  • TRIANGLE
  • SAW
  • PULSE WAVE (with  manual pw)
  • NOISE

PW KNOB

SCALE (32-16-8-4)

VCO2 has :

WAVE SELECTOR:

  • SAW
  • SQUARE
  • PULSE
  • RINGMOD

PITCH KNOB (fine tuning)

SCALE (16-8-4-2)

The two vcos sounds very warm and fat with a classic japanese sound.
The saw waves are quite “smoothed” and not really ripping (as the classic american saw of moog , sequentials, etc.)
The pulse/square wave is really fat and smooth too.
The smoothness of the oscillators maybe also produced by a particular “cut” of the VCFs and VCA that are not bypassable.

VCFs

The filters are the most carachteristic element of this synth, the trademark of the MS20′ sound is the dual filter with resonance (PEAK).
Both the HPF that the LPF have the same controls, the FREQUENCY CUTOFF and the PEAK (that’s the RESONANCE!).
The slope of the filters is 12dB/oct and though they are resonant they are not self oscillating.
The use of the filters makes this synth anhighly versatile machine, because they are not strightly “multimode”, but can be used in combo to obtain particular combinations mantaining two indipendent peaks of resonance.
A famous use of the HPF is to boost the low frequencies oto saturate the sound.
Thanks to the resonant HPF , turning up the peak  creates a gain of level at the cutoff frequencies  that results in awesome sub basses or highly saturated sounds.
The behaviour of the filter is also particular because when the peaks are up the frequency of the cutoff tends to oscillate producing highly harmonic and saturated timbres.
The MS20 was produced with two different components , the first (older) series has the famous  Korg35 that is considered less “muddy” , while the following series use common components.
Both the HPF that the LPF have a smooth behaviour and a rounded sound with the peaks at minimum, while raising up the peaks leads to the aggressive and distorted side of the synth.

ENVELOPES

Env 1 is a simple Attack -Release with  Delay,useful for modulations and harpached to the VCO pitch modulation.
ENV2 is a HADSR, it works like an ADSR but has a hold for that lovely drones the MS20 is so great at, or to use the synth as a efx/filter processor for external signals.
ENV2 is prepatched to VCA and VCFs modulations.
Both the envs are punchy with fast attack and decay, and work very well for every type of sound, from percussive to ethereal.

MODULATION GENERATOR

MG is how Korg labelled the LFO.
The MG consist of a low frequency oscillator that produces morphable square and saw waves .
The saw can morph from saw to tri to ramp.
The square goes from imp to square to inverted imp.

The two row of knobs under the filter and vcos sections are dedicated to the modulations.
The higher row has the MG as modulation source,and the pitch, and cutoff of the filters as destinations, while the lower row has as source the ENVs, env 1 to pitch and env2 to filters.
Every parameter has its own amount knob.

On the left there are two keyboard controls, PORTAMENTO and tune.

This is a description of the “prepatched” part of the synth, but using the patchbay almost everything can be routed to every target, the flexibility is one of the most important carachteristic of the MS 20, a compact synth , highly versatile and awesome sounding.

The Korg MS Serie

Korg MS-20 and MS-50

Korg MS-20 and MS-50

At the end of the 70s the japanese synth market became very busy.
The leading brands were Korg , Yamaha and Roland.
While Yamaha’s target was mainly on low budget prepatched monosynths users, Roland and Korg were on the low budget side but with an interest in producing low cost modulars for the masses.
Roland at the age had the SH serie that targeted prepatched synth users while the system 100 was towards low budget modulars/semimodulars and the System700 was a Pro-Studio product.
Korg had a different approach, the MS and PS series were mainly mono and poly semimodulars that could be used as standalone prepatched instruments as complex systems linked together.
The MS serie was composed by the MS10 (the little 1 vco, 1 vcf, 1env basic synth), the MS20 (the 2 VCO bigger brother with many added features), the MS50 (the modular expander, full of the less common modules on synths of that period) and the SQ10 (3 track sequencer).
Even if the components used on MS synths were mainly the same, due to different electronic construction the three models have slight different sounds.
The MS10 is considered by some the more aggressive as filter behaviour (compared to the MS20) and because of the presence of pulse width modulation (absent on the MS20).
The MS20 is the more versatile of the three as can work as a synth (with lots of features), efx processor, and can be controlled even with audio signals!
The MS50 is the only real modular of the serie, it must be patched to produce sounds, and has a vast array of particular features as 2 ringmodulators, the vc lfo, the vco with multiouts, logic modules, the volt-meter, etc…
While the MS10 is a “straight” synth if used standalone, the MS20 is a good soundesign machine but it is a real awesome modular when used in junction with MS50 and the SQ10.
The MS50 can be used to produce linear or exp FM, or to fatten up the sound, with 3 vco, 3 filters 4 env etc this little modular is really awesome!
Compared to the “high end” modulars/semimodulars of the period , like the ARP 2600, EMS Synthi, Moog Systems, the MS serie has a more “noisy”and less harmonic carachter, but while back in that days were mainly considered  low budget modulars, now are considered great sounding machines because the approach at making music (especially electronic music) is really changed.
Every electronic music producer uses or has used an MS in  his career.
In the late 70s and early 80s MS10 and MS20 were widely used by new wave synth pop bands  as O.M.D. , Human League, Depeche Mode.
During the 90s every techno , electronic , producer used one or more than one.
Just to name a few Aphex Twin uses 4 MS20 , Autechre uses MS20 and MS10, Coldcut used extensively the MS20 , Mr.Oizo (MS20) , Portishead (MS20 & MS50),Daft Punk, Chemical Brothers…

Later I’ll analize deeper the MS20 & MS50 combo, stay tuned!
