Setting Effects

The VF80 provides 38 digital effect types used for the loop effect and 6 types used for the insert effect. As you can select any type and adjust parameter settings for each type, comprehensive effect pro- cessing is possible.

Employing the Fostex A.S.P. (Fostex Advanced Signal Processing Technology*), the internal DSP multi- effect processor realizes superb ambience effects. In addition, the newly developed "A.S.P. +" achieves simulations of microphones/amplifiers with overwhelming reality.

<About "Loop effect" and "Insert effect">

Using a loop effect you can process sound recorded on tracks during track bouncing (ping-pong) or mixdown. The processed sound is recorded to the other track(s) of the unit or external master recorder.

Using an insert effect, you can process sound on any of tracks 1 through 6 using a distortion or simulation effect, and rerecord the processed sound to the same track.

* A. S. P. (Fostex Advanced Signal Processing Technology)

The A. S. P. is an exclusive new digital effect processing technology designed by Fostex. This method extracts maximum efficiency from the limited DSP power.

It achieves an overwhelmingly high density Early Reflection sound and wonderfully smooth High Dump response through the H. F. A. (Harmonic Feedback Algorithm). Also, it car- ries out an elaborate reverb simulation with clear sounds through the H. D. L. P. (Hi- Density Logarithmic Processing), which eliminates the mutual interference between the numerous integrated delay modules and reduce the impurity and girt of the sound.

* H. F. A. (Harmonic Feedback Algorithm)

There is one of indispensable elements in the natural echo called “Early Reflection Sound,” which is usually sacrificed in commercial reverb products in order to reduce costs. (In practice, the Early Reflection Sound means the very first reverberated sound that bounces back from walls, floors and ceilings of concert halls). The entire reverb sound quality depends on this Early Reflection Sound and how closely it can resemble the real echo. The H. F. A. is an algorithm that enables the effect unit to reproduce a clear and natural Early Reflection Sound by applying an ideal harmonic feedback to each delay module.

* H. D. L. P. (Hi-Density Logarithmic Processing)

The reverb sounds consist of lots of small delay elements combined in a complex way, which are produced by many delay modules inside the effect unit. In order to obtain smooth and comfortable reverb sounds, it is very important to efficiently organize the relationship between each delay module and minimize negative mutual interference. The H. D. L. P. is a technology which applies efficient logarithmic processing to each delay module, so that they can work in the most efficient way in order to eliminate harmful reverb elements and roughness. This makes it possible to establish high density and transparent sounds.

About "A.S.P.+"

Combining the ambience effect technology established through the development of "A.P.S."with acoustic theories accumulated through the development of transducers such as monitor speakers for many years, Fostex developed a unique simulation algorithm engine called "A.S.P.+", which performs overwhelmingly realistic microphone/amplifier simulation.

To simulate a microphone, the frequency response of the microphone, which is the most essential factor that decides the sound character of each famous/popular microphone, must be reproduced correctly. To get this, "A.P.S.+" carries out a double accuracy operation for each frequency range using the unique "D.A.O." (Double Accuracy Operation).

Regarding a guitar amplifier, the peak and dip of the specific frequencies, as well as feedback of the peak frequency's harmonics, are the most essential factors that decide the sound character of each famous/popular amplifier. To simulate such a unique character, "A.P.S.+" carries out a double accuracy operation for each frequency range using the "D.A.O." (Double Accuracy Operation) to simulate the frequency curve, as well as carries out harmonics feedback processing using the "H.F.A." (Harmonics Feedback Algorithm).
