Magical FDS Plug

About

What is Magical FDS Plug?

Magical FDS Plug is a software synthesizer in plugin format that reproduces the timbres of so-called "Disk System sound sources" (FDS sound sources). It can be used within Mac/Windows host applications that support Audio Units and VST3.

The FDS sound source has a unique mechanism in which a 64-sample waveform memory (carrier) is modulated by a separate 32-step instruction sequence (modulator). While it is a sound source that is difficult to configure due to its high degree of freedom, this plugin provides an interface that allows you to construct waveforms in a logical way, such as additive synthesis and preset transformation, while maintaining that freedom.

Features

Two systems—Carrier and Modulator—allow you to independently design the audible basic waveform (carrier) and the sequence of instructions that modify it (modulator).
