Csound Synthesis Approach for the iVCS3 iOS App

This article is about the process of creating an iOS based app for the digital emulation of the famous electronic synthesizer VCS3 by EMS using a Csound orchestra as its sound engine. Despite the out of standard features of the original instrument, we have attempted to clone a large amount of details regarding the sound generation, the connectivity, the look and its specific original ergonomy. We will try to illustrate the general synthesis strategies adopted in creating this musical synth application and in particular, we will focus on Csound code from the main sound modules and their relative individual modeling approach.
