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 Reverb
Chromaphone is equiped with a simple reverb which can be used to add ambiance to your sound.
The Reverb knob is used to set the amount of wet signal in the mix, turning the knob clockwise
increases the amount of reverberation in the signal.
5.6 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.
5.7 Level Meter
The level meter allows one to monitor the RMS (root means square) level of the left (L) and right
(R) output channels from the synthesizer. As soft clipping is applied to the output signal in order
to limit its amplitude, 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
a headroom of 20 dB which should be more than enough to cover the dynamics of most playing
situations and therefore guarantee that no additional distortion is added in the output signal.
Distortion is introduced by the output when the signal enters the red section of level meter
which starts 3 dB below the clipping value. A peak value mark allows one to follow the maximum
level values reached by the output signal and therefore to determine if clipping as occurred or not.
5.8 The About Box
The About box is open by clicking on the chevrons located at the very top of the interface. The box
is closed by clicking again on the chevrons or outside the box. Useful information is displayed in
this box such as the program’s version number, the serial number that was used for the authorization
and the the email address that was used for registration. The box also includes a link to the pdf
version of this manual.
