Overview

SOFT MALLETS, FULL STEREO

The VibysM is a 3 1/2 octave Musser concert vibraphone, one of the best vibraphone models ever made. It was played with soft mallets to capture the widest dynamics and all the softness of the instrument, and recorded in ORTF configuration for a full stereo image.

The vibraphone was very popular in the jazz of the 50's and was used much less afterwards, but today it is back in popular music, modern jazz and even electronic music. Around 411 samples, with 9 velocity layers for the sustain and 3 for the releases.

Features

The motor

The motor

Vibraphones often have a motor: a spinning bar that blocks all the resonance tubes at once, giving the instrument its famous vibrato. It is so characteristic that some players never play without it, so the VibysM simulates it, with its rate and an on/off switch.

You can also set the depth of the effect - not really possible on a real instrument, although it varies from one vibraphone to another.

More about this

Motor

On / Off: turns the motor simulation on or off

Rate: the speed of the motor

Depth: the depth of the tremolo

Release, pedal and sensitivity

The releases and the sustain pedal noises, triggered automatically, each have their own volume, so you decide how much of the instrument's mechanics you hear.

The sensitivity adjusts the library to your taste and your playing, by setting how quiet the softest notes are.
