OutputUnit()

The constructor creates an OutputUnit, which by default maps the virtual channels to physical channels of the same number.

~OutputUnit()

This destroys the OutputUnit.

T& operator()(ioref n, int c)

This references the physical channel for node n and virtual channel c. The channel mapping can be read and modified this way.

void iterate(void (*func)(ioref n, int c, uchar* e, void* x), void* x)

This iterates over every node/channel combination, and calls func exactly once for each. func is given the node n, the virtual channel c, the physical channel e, and the additional pointer x which was passed by the caller.

void write(MIDI_msg m)

This sends the MIDI message m to the synthesizer, after first converting the virtual channel to a physical channel. Meta events are not actually sent to the synthesizer.

void write(MIDI_msg m, int n)

This sends n copies (must be greater than or equal to 1) of the MIDI message m to the synthesizer, after first converting the virtual channel to a physical channel. Meta events are not actually sent to the synthesizer.
