When the shelving mode is selected, frequencies beyond the shelf are not simply attenuated, they are attenuated in a very musical way that has been derived from our vast library of VCM research data.”Ī quick note about Mr. Ishizuka: “The selectable shelving response of the Dynamic EQ4 effect is a characteristic that has been made possible by VCM technology. ABOVE and BELOW mode switches are provided for each band, and these can be used in conjunction with the RATIO control to produce a level boost when a specified level is exceeded, gate-like operation in which the signal is allowed to pass only when a preset level is reached, as well as compressor-like level reduction when the set level is exceeded.

It seems that the Dynamic EQ4 equalizer can function as a type of sidechain effect when used to control overlapping frequencies as described above by Mr. Like the MBC4, the four-band Dynamic EQ4 equalizer included in the RIVAGE PM10 is a new processor built on VCM technology. A number of live sound and recording engineers actually used the processor during development, and we made adjustments based on their feedback to ensure that it would be easy to use.” They are not VCM emulations of any specific existing equipment, but entirely new features created using VCM technology. Ohshita: “All of these parameters are based on VCM know-how accumulated by K’s Lab through years of research. The HARMO switch can also be engaged to add warmth and depth as well as sparkle, improving the way sounds blend. OPTO is a good choice when a natural sound is desired. The OPTO setting has slower attack and release response, so you don’t hear the compressor working. The VCA “flavor” results in solid compression with clear level control, and is ideal for situations that require tightly controlled compression. The switches mentioned are located in the lower right corner of the interface.

To make adjustment easier, we added FLAVOUR (VCA and OPTO) and HARMO switches that help users achieve the sound they’re after.”

We also tweaked the size, color, and contrast of the on-screen text and controls until we were totally satisfied. Ohshita adds: “We really wanted to make it easy to “read,” so we adopted a graph type display with color coded frequency bands. K’s Lab has been engaged in research and development at the forefront of sound technology for approximately 30 years. The group spearheaded the new field of virtual acoustic technology in its early years, and later teamed up with audio legend Rupert Neve to digitally recreate some of his most famous and sought-after designs from the past using modeling technology.

We interviewed the researchers who developed the MBC4 multiband compressor and Dynamic EQ4 four-band equalizer included in the RIVAGE PM series digital mixing system, and the extremely popular THR series compact guitar amplifiers, and will focus on those products in this article.Īs mentioned in previous installments, K’s Lab is a research group led by Yamaha research fellow Dr. Rather than recreations of classic equipment, the products discussed in this installment are new designs based on the results of K’s Lab research. We met the one-of-a-kind sound research group, K’s Lab, in two preceding articles: “How the discovery of a 1977 thesis led to a breakthrough at the Yamaha K’s Lab research division 30 years ago,” and “Rupert Neve designs from the 60s and 70s realistically recreated by the Yamaha K’s Lab research team.” In this, the third and final installment of the K’s Lab series, we will take a look at some of the processors and guitar amplifiers that have been created using their VCM (Virtual Circuitry Modeling) technology.
