Architecture of String Studio VS 13

2 Architecture of String Studio VS

2.1 General Signal Flow

String Studio VS is a synthesizer built around a String module which acts a a sound source. The

general architecture of the synthesizer is presented in Figure 3 and follow the functioning of a real

string instrument.

Figure 3: General signal ﬂow of String Studio VS.

It is the vibration from the String which constitutes the main sound production mechanism of

the instrument. The string is set into motion by the action of an Exciter which can be a hammer, a

pick or a bow. The frequency of the oscillation is determined by the effective length of the string

which is controlled by the ﬁnger/fret interaction or Termination. A Damper can be applied on

the strings in order to reduce the decay time of the oscillation. This is the case on a piano, for

example, when felt is applied on the strings when the keys and the sustain pedal are released. The

vibration from the string is then transmitted to the Body of the instrument which can radiate sound

efﬁciently. In some instruments, the string vibration is transmitted directly through the bridge. In

other instruments, such as the electric guitar, a Pickup is used to transmit the string vibration to an

ampliﬁer.

In addition to these main modules, a Filter module has been included between the String and

Body module in order to expand the sonic possibilities of the instrument. A Distortion module and

an output effect stage complete the synthesizer as illustrated in the signal ﬂow diagram of Figure 4.
