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 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.
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.
