56 Utility Section

Selecting a Scala ﬁle in the list automatically triggers the loading of the corresponding temper-

ament. The reference note that will be used as the base note for the scale described in the Scala ﬁle

can be set using the Reference Note control appearing at the bottom of the Tuning window. The

frequency of this reference note is calculated relative to the settings of the Tune control.

5.3 Polyphony

The Voices control located below the Tune button allows one to adjust the number of polyphony

voices used by String Studio VS. The number of voices is adjusted by clicking on the control and

selecting the desired number of voices. In general, a higher number of voices is desirable but keep

in mind that the CPU load is proportional to the number of voices used.

5.4 History and Compare

The History control allows one to go back through all the modiﬁcations that were made to programs

since the application was started. In order to travel back and forth in time, use the left and right-

pointing arrows respectively. The application will switch between different program states and

indicate the time at which they were modiﬁed.

The Compare button, located above the Program display, is used to switch between Edit and

Compare mode. This button is visible only once a modiﬁcation is applied to a given program. It

allows one to revert to the original version of a program in order to compare it with the current

version. When in Compare mode, edition is blocked and it is therefore not possible to modify any

parameter. The Compare mode must then be switched off by clicking on the Compare button in

order to resume edition.

5.5 Volume

The Volume knob is the master volume of the application. It is used to adjust the overall level of

the output signal from the synthesizer. General level is increased by turning the knob clockwise.

5.6 Level Meter

The level meter allows one to monitor peak and RMS (root means square) level of the left (L) and

right (R) output channels from the synthesizer. As a limiter is located at the output of String Studio

VS, it is important to make sure that the amplitude of the signal remains within values that ensure

that no distortion is introduced in the signal at the output.

The 0 dB mark on the level meter has been adjusted to correspond to -20 dBFS (full scale). This

means that at that level, the signal is -20 dB below the maximum allowed value. This 0 dB level

mark should typically correspond to playing at mezzo forte (moderately loud) level. This ensures
