If the Acxel II Automated Sound Builder (ASB) is used to set the initial sound configuration, it will create a number of sinewave cells with automated drawn Amplitude and Frequency spectra and envelopes.
Once done, the musician has complete access to the 4 parameters on spectra (4 x 2) and envelopes (2 x 2) for editing.
Acxel II Additive Synthesis module becomes the natural solution to create / edit timbre and apply MIDI controls to selected sound elements. Sound can be extracted from the Automated Sound Builder (ASB) (from pre-recorded sound or wavefile - new step-up from the original Acxel so called Acxelizer ) or created from scratch.
A large selection of parameters is accessible through the graphic interface. Using this interface, the sound can be modified or made structurally different with independently assigned MIDI controls. As an example, you can automatically build 2 different sounds and use MIDI control to gradually morph from one sound to the other. These modifications apply to all sound parameters, including envelopes and dynamic expression.
