Member Function Documentation

void CsoundMidiInputStream::EnableMidiInput

(

CsoundArgVList *

argv

)

Enables MIDI input for the associated Csound instance.

Should be called between csoundPreCompile() and csoundCompile(). If 'argv' is not NULL, the command line arguments required for MIDI input are appended.

int CsoundMidiInputBuffer::GetMidiData	(	unsigned char *	buf,
		int	nBytes
	)		[protected, inherited]

Copies at most 'nBytes' bytes of MIDI data from the buffer to 'buf'.

Returns the number of bytes copied.

		unsigned char *	,
		int
	)		[static, private]

void CsoundMidiInputBuffer::SendChannelPressure	(	int	channel,
		int	value
	)		[inherited]

Sets channel pressure to 'value' (0 to 127) on 'channel' (1 to 16).

void CsoundMidiInputBuffer::SendControlChange	(	int	channel,
		int	ctl,
		int	value
	)		[inherited]

Sets controller 'ctl' (0 to 127) to 'value' (0 to 127) on 'channel' (1 to 16).

void CsoundMidiInputBuffer::SendMessage

(

int

msg

)

[inherited]

Sends a MIDI message, 'msg' is calculated as follows: STATUS + DATA1 * 256 + DATA2 * 65536.

void CsoundMidiInputBuffer::SendMessage	(	int	status,
		int	channel,
		int	data1,
