Product Overview

Chromatix is a celebration of yet another successful resurrection of an old classic saved from the grave…

This time it was a gorgeous 1983 Rhodes Chroma!

After a very deep clean inside and out followed by a visual inspection it was quickly realised the original rather large and somewhat grizzly linear PSU had burnt out and was showing signs of several past repairs. News got round that a new cooler running switched mode PSU retrofit had been made available and was duly installed. Having returned power to the beast it quickly transpired that at least two voice cards had serious issues and were failing the dreaded auto-tune. This rapidly became a can of worms when it became apparent that almost all of the considerable number of analog multiplexors within the beast were practically dying in front of my eyes due to age and after the shock of being pressed back into action for the first time in several years. Following removal and replacement of some 40 or so unsocketed ICs much of the instrument returned to life leaving a final stubborn voice card really determined not to play ball. On discovery of a number of leaky transistor arrays and tired charge pump oscillators the final voice card eventually succumb to my continued harassment only to have a third voice card fail during soak testing!

After two weeks of intense toil this 16 VCO beast returneth to life… and what a beast!

ARP's last gasp

ARP Instruments, the hugely influential name behind a string of famous instruments such as the ARP2500, ARP2600, Odyssey, Avatar, Omni, Quadra and Axxe, was in its prime during the 70s but by the early 80s the tables had turned for the worse and the company was losing money hand over fist thanks to a series of unfortunate business decisions, excessive cost of sales figures and overheads.

Work had started on the Chroma in the autumn of 1979. After two years of intense development interspersed by the project being temporarily shelved on a number of occasions things were looking decidedly shaky at ARP on the financial front. This was no fault of the R&D team behind this technically challenging design but due to increasing resistance from management who had their own battles to fight.

56 Unique Instruments

Chromatix features a deceptively powerful layering engine which allows the user to create new sounds and textures with ease by selecting up to four out of a bank of 56 partial voices to be layered. Each layer has its own fine and course tuning, ADSR envelope, panning, velocity sensitivity, LFO and tone controls. This permits anything from huge pads to complex evolving sounds. Many of the demo instrument patches included are good pointers as to how some of these effects are achieved.

Above of each of the four voice panels there is an orange LCD display showing the selected voice. By clicking on each of the displays a pull down menu appears allowing one of 56 voice partials to be selected. With a potentially vast number of layered permutations at hand two different banks of 28 partials are available the first set assigned to channels 1 & 3 and the second bank of 28 partials assigned to channels 2 & 4.

Layering Engine

Naturally the example instruments packed with the library can be used as is but where the fun starts is having a go dialing in your own sounds using the intuitive layering engine. All of your creations can be saved as .nki instruments simply by using the save as function by clicking on the files icon in the main Kontakt control pane.

The layering engine consists of four identical programming panels and an effects section. This release is the first to use a recently updated version of the layering engine which has recently been revised to include separate velocity sensitivity controls for each layer.

The TONE control is a deceptively powerful feature. In the fully downward position the signal is unaffected. As the control is moved upwards a continuously evolving complex EQ curve is applied. With some experimentation this feature can be used for embellishing formants within each voice partial and helping to sit each of the layers together in the mix.


System Requirements:

  • This library requires the full version of Kontakt 4.2.4 or higher.
  • Approximately 1.35GB of free hard disk space is required.

16 VCO Analog Synth

Philip Dodds was left to head a company dying before his eyes and several months of development were lost to company politics. The situation became dire and he was eventually left with little option but to close down the R&D department. Despite the ongoing stress of the situation he succeeded in selling on the IP rights to the Chroma design to CBS Musical Instruments and in the process was hired to oversee its production. If it wasn’t for this last gasp for survival the Chroma would surely never have existed.

The Chroma was an advanced digitally managed 16 VCO analog synthesizer released after the initial success of the Sequential Prophet-5. Both instruments offered patch memory with the Chroma sporting a bank of 50 user programmable patches. It was one of the first analog synths to offer multi-timbral operation, voice layering and keyboard splitting with velocity sensitivity. The voice architecture was unusually flexible whereby the firmware could route signals through two low pass filters, in parallel or series, or switch the VCA before or after the filters. Through a bespoke digital interface (Chroma pre-dated MIDI) it was even possible to edit voices in a program on the Apple II computer.

CBS released the Chroma in 1981 with a list price of $5295 and proved to be pretty successful with estimates of around 1400 units eventually sold.

Great selection of patches

Great work in sampling and compiling these patches, great for track starters, luscious pads and underscores.

Chromatix un bon Rhodes Chroma !

Chromatix c'est un Rhodes Chroma sur Kontakt, pas cher, réglage simple et efficace, 75 presets et un son, cooool.
C'est plus un orgue qu'un vrai synthé, mais en le triturant un peu on arrive a du Rhodes Chroma et c'est émorme.
De préférence utiliser des effets externe (Hardware) comme Lexicon, DBX, TubeTech, Filtre Moog, etc, pour lui redonner du "Juice" et du grain, ce qui lui apporte juste ce qu'il manquait pour être parfait ;-)
A utiliser sans modération pour tout style de musique, moi j'adore
Bravo Hideaway Studio

Love at first patch

The first preset brought to mind a Hungarian composer and Madona's "Live To Tell." Hideaway Studio often uses a single-tab, 4-voice layering interface which quickly becomes familiar because it's straight-forward, easy to use, quick, and effective. The interfaces generally differ in graphics and vertical/horizontal layouts but the well-planned basic functionality, effects, and IRs are comfortably consistent between libraries, with minimal modifications between units (Chromatix has Velocity Level and ADSR). Multis don't appear to pose any CPU surprises with Hideaway synths (I've had as many as seven running simultaneously without issues). No sequencers/ARPS, "morphing" is via old-school DAW automation/MIDI-learn, and the seemingly-simple LFO (actually bipolar) and Tone controls deserve attention when reading the manual. The manual is well written: The technical aspects are clear and consistent, and the background and historical insights are a delight. The creation, quality and selection of samples/voices is the major difference between many Hideaway Studio libraries (Chromatix has 56 different voices---two pairs of 28 voices, paired to layers 1&3 and 2&4, for over 600000 voice combinations), and those aspects are very well done. The simplicity and streamlined features are double-edged swords, but I'm still giving this five stars because of the ease of use and quick, consistent, good results you get.

Excellent Carpenteresque Sounds

This is a great Kontact library and like the title says you can get some great John Carpenter style sounds out of it. It has some great presets and is easily tweakable to get the big synth sounds that you want.

Great synth horns!

I love the warmth and fatness of the synth horn patches...really a lovely sound. Also, the interface is great. Everything is there in front of you and you have 4 oscillators to change sounds to your hearts content.

Lots of analogue colours

This a based on the real synth Rhodes Chroma.
I don't know the original, but can judge on this sampled one and it's great. The sound palette is huge and more on the lush, softer side.
There are choirish sounds, arps and also such with shorter decays. Some recreate real instruments, some not - so there are beautiful spacy presets to find eg.

There are four layers, so you can combine sounds on your own.

Awesome Chroma Library!

Dan does it again! This is a great Chroma library with tons of character. There are many libraries that capture this synth. However, if you’re looking for one with true character, this takes the cake!

Probably not if your looking for a neutral capture of this synth, but then again who really wants something like that!

Definitely not me! Love how hideaway captures instruments in a way that builds further on their original character. Must buy!

Demo - I Wish I Was a Carpenter

This demo from Mike Evans was created using sounds from Chromatix except for the bass drum. Everything else is Chromatix. Enjoy!
