Polyphony
The modules can be either monophonic or polyphonic. The polyphonic modules are distinguished by the shadow behind them in the structure window. A polyphonic module has a separate instance for each voice allocated in the current instrument.
A new voice is allocated each time the user presses a MIDI key. The maximum number of voices is specified in the instrument settings. If there are no free voices the oldest voice is deallocated (so-called latest note priority).
The voice deallocation is controlled by the VR module of the instrument. Usually for normal deallocation you should connect this module to the amplitude envelope activity signal. See the VR module description for more detail.
Sometimes a module is not entirely polyphonic, but some internal part of it is polyphonic and some not. From the user point of view this is seen as some outputs of the module being polyphonic and some monophonic. The monophonic outputs of a polyphonic module are shown by > signs next to them.
The module polyphony is controlled automatically by the SynC Modular in most cases. A polyphonic signal routed to a module usually causes the module or some part of it to become polyphonic. Initially the polyphonic signal is taken from the modules which always produce the polyphonic signal (e.g. MIDI Note Frequency).
Some modules cannot accept the polyphonic input signals (e.g. the WaveOut module). An attempt to do so results in a non-functional wire denoted by > signs next to the input. Before you can route the polyphonic signal to such module you need to combine all voices of the signal. This is done by VC module.
