Logan 21977 was a great year. Star Wars came out in the cinemas. The Queen had her Silver Jubilee (where I got to dress up like a policeman in our school parade). And the Logan String Melody II was released.

The String Melody had come out a few years earlier, in 72, but hadn’t been much of a hit. The mk II changed all that, earning itself a spot in the pantheon of All Time Greats. It looked stunning, with lavish 1970s real wood veneer and a delightfully responsive waterfall keyboard that made it a real player’s instrument. But that wasn’t why it was a hit.

The reason is very simply to do with the sound it makes. It doesn’t sound much like a real string ensemble, but it sounds amazing regardless, and it’s graced a thousand hit tracks as a result. It’s thick, warm, rich, thoroughly analogue, and yet at the same time airy. It’s controllable, with drawbar-style faders to combine registrations, and attack and release controls too. And the five “Preset” buttons offer different settings of vibrato and chorus effect across all those synthesised strings, giving you huge, swirly, gorgeous acreages of pads that stretch on into the sunset… And we’ve sampled every last wonderful resonance of it for you!

The Logan String Melody II bunches most of its controls within easy reach of the player’s left hand, so let’s take a quick guided tour. The silver push-buttons are the Preset selectors. Each of these engages one of the Presets: a combination of string settings, chorus settings, and LFOs that defines the basic sound the keyboard makes. Most of these – all except Orch., in fact – can then be adjusted further with the drawbar-style sliders below (in nice bright 70s colours!)

Logan keyboard working

The red and blue “String” faders operate like typical organ drawbars: top is off, bottom is loud. They control three String registrations per set – Cello, Viola and Violin – which are effectively the same tone but played at pitch for the Cello, then one octave higher for Viola, and two octaves higher for Violin*. Mixing these up is very simple and gives you an instant orchestral ensemble effect. The red drawbars control the sound to the left of Middle C and the blue ones control the sound to the right, so you can set them identically for a whole keyboard of string wonderfulness, or have different registrations in the bass and treble.

The yellow drawbars are for the Bass tones: Perc, which is a one-shot percussive bass sound, and Bass, which is a good deep  analogue growl. These can be blended in to the String sounds, but they only operate to the left of Middle C. Or you can disable the String drawbars and just play the bass sounds on their own, for really deep analogue bass tones. They sound gorgeous.

So on the original Logan, the sounds that emerge alter drastically depending on which Preset you have engaged. The Organ preset sounds utterly different to the Orch. preset. This was part of the reason that we broke our Rhythmic Robot version of the instrument out into five separate Kontakt instruments.

What you get, then, is five Kontakt instruments, one for each of the Presets – so you can load them individually to mimic the original Logan, or stack them up any way you like for even richer, thicker, warmer stringscapes! There was no way to do this on the original, since engaging one Preset popped out the buttons for all the others. But hey, this is a whole new millennium, and now you can have Organ with Acc., or ‘O’ with Orch., or even the whole damn lot of them blended up into a sumptuous frenzy of swirling chorus and swooping LFOs. Let’s go crazy!

Logan rear panelThere’s more. We thought you’d like a bit more control than just Attack and Release, so we’ve slotted in a standard ADSR envelope on the front panel. Round the back, there’s more still: additional Chorus and Phaser effects (so you can add Chorus to, say, the Acc. setting, which doesn’t usually have it), plus separate Vibrato and Tremolo controls (with Depth and Rate), a nice warm Tube distortion circuit, and a set of cab models to emulate the sound of the Logan playing through an amp. These open up a whole wealth of different soundscape possibilities: we particularly like the cab effects, since the naturally spacious sound of the Logan can be made growly, dark, glowering and sinister with one cab, or thinned and made “smaller” for easier siting in a busy mix with another. Add in some Tube distortion and you can use the Organ preset as if it were a Hammond (though of course it sounds very different indeed!) This is where you’ll find the opportunities to build your own tones that extend far beyond the palette of the original instrument.

“Each instrument has a set of effects, such as chorus, phaser and cab simulation, the last capable of beefing up the Organ preset to pulpit-shaking levels, while the chorus and phaser transform the Solo preset, especially, into a pleasing alternate string synth. The samples are well recorded and every parameter is MIDI controllable… Actually, the biggest audible difference from the real thing is the lack of noise. I’ve never heard a Logan sound so clean!” – Sound on Sound magazine, November 2012

We really went to town on the sampling, too. Each chromatic note of the four-octave keyboard was sampled at 24-bit, for each of the registration stops, on each of the presets. These are long samples, too, to give the sound time to evolve, and they’ve been looped very carefully to preserve the cyclical components of the chorus effect. This makes Logan one of our larger instruments in terms of sheer Megabytage, but we really think it’s worth it.

(All our Kontakt instruments require a full copy of Native Instruments Kontakt v4.2.3 or higher (including all versions of Kontakt 5). Kontakt Player is not supported: instruments will load, but will time out after 15 minutes. See the FAQ for further information.) You can read more about the original String Melody II here.

“The Logan String Melody and the later Melody II are justifiably revered string machines. Of 1970s Italian manufacture, the String Melody was a split keyboard instrument with separate attack/release envelopes for each half of the split. There were dedicated mixer sliders for ‘cellos’, ‘violins’ and ‘violas’, plus two for the left hand’s bass part. Unusually, these were at their maximum volume when fully down, not up.Pressing the five preset buttons (of the Melody II) introduced different variations of chorus and vibrato to the synth’s basic tone, and it’s these that form the basis of the latest set of Kontakt instruments from Rhythmic Robot. Collectively they’re called ‘Logan’ and comprise Accordion, Solo, Orchestra, ‘O’ and Organ.

Some string machines are easier to sample than others. The Korg Lambda, for example, has three detuned oscillators, meaning that you can capture its sound accurately by sampling every note. Instruments like the Logan present more of a challenge, as there’s a rich blanket of chorus (created by a bucket-brigade delay and two LFOs) to consider. The occasional small glitch in some of the loops is most noticeable when sustaining individual notes, but even the relatively pure tones of the Solo instrument contain a subtle vibrato that can defy perfect looping. These few imperfections aside, Rhythmic Robot have successfully bottled the essence of each instrument. This means that you get the slightly weedy Accordion and Solo presets, the thick and lush Orchestra, the surprisingly playable Organ (church-like) and the enigmatically named ‘O’, which is actually fairly close to Orchestra.

As you’d expect, sliders mimic the Logan’s left- and right-hand mixes of violins, violas and cellos. Other than pitch separation, there’s no tonal difference between these three instruments but when mixed together they create an ensemble that ranges from lush and warm to thin and ghostly. You can also choose how much of the two left-hand bass instruments are included, via the Perc and Bass sliders. The Logan’s simple decaying bass was vaguely reminiscent of a string bass, while its sustained bass was reminiscent of nothing in particular. Unlike the original, this version is polyphonic. Also, the original machine had separate attack and release sliders for each half of the keyboard but here there’s a global ADSR, so it doesn’t quite offer the same possibilities.

Each instrument has a set of effects, such as chorus, phaser and cab simulation, the last capable of beefing up the organ to pulpit-shaking levels, while the chorus and phaser transform the Solo instrument, especially, into a pleasing alternate string synth. Finally, there’s a vibrato/tremolo section with variable speed and delay, which is useful.

Overall, each instrument ‘handles’ close enough to the real thing for most recording and performance applications. Actually, the biggest audible difference is the lack of noise. I’ve never heard a Logan sound so clean, and it’s an unusual experience to play one without reaching for a noise gate. As with other RR instruments, the samples are 24-bit mono and well recorded, and every parameter is MIDI controllable. Incidentally, you can eat up lots of polyphony due to the layering of samples, as even when a volume slider is at zero, resources are consumed.

You’ll need the full version of Kontakt, rather than the player version, and V4.2.3 or later is recommended. If I were cherry picking, I could probably be satisfied with just the Orch and the Organ instruments, but at a fiver for each instrument (or £19.95 the set), you can’t go far wrong.” – Sound on Sound magazine

    Logan II is magical, my favourite string machine! It is warm, thick and airy at the same time!! Claudio Simonetti used this in some of the Goblin’s soundtracks.
