Utility Section 37
5 Utility Section
The utility section is located at the top of the Chromaphone interface and it includes important
parameters and monitoring tools. For information on Banks and Programs please refer to Chapter 2
5.1 The MIDI LED
The MIDI LED is located on the left of the level-meter. The LED blinks when the synthesizer
receives MIDI signal. If the application is not receiving MIDI signal, make sure that the host
sequencer is sending MIDI to Chromaphone.
5.2 Polyphony
The Voices control located above the Volume knob allows one to adjust the number of polyphony
voices used by Chromaphone. 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.
5.3 Tuning
The Tune control is used to transpose the frequency of the keyboard. This control is composed of
two numbers separated by a dot. The first number indicates a value in semi-tones while the second
one indicates a value in cents (one hundredth of a semi-tone). The amount of transposition can be
adjusted by click-dragging on the semi-tone and cent controls. Double clicking on these controls
brings back their value to zero.
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
