<U>DESCRIPTION</U></H4>
Send stream of note-on and note-off messages to the MIDI OUT port.
<H4>
<U>PERFORMANCE</U></H4>
<I>kchn</I> - MIDI channel number (0-15) <I>knum</I> - note number (0-127)
<P><I>kvel</I> - velocity (0-127)
<P><I>kdur</I> - note duration in seconds
<P><I>kpause</I> - pause duration after each noteoff and before new note
in seconds
<P><B>moscil</B> and <B>kon</B> are the most powerful MIDI OUT opcodes.
<B>moscil</B> (midi oscil) plays a stream of notes of <I>kdur</I> duration.
Channel, pitch, velocity, duration and pause can be controlled at k-rate,
allowing very complex algorythmically generated melodic lines. When current
instrument is deactivated, the note played by current instance of <B>moscil</B>
is forcely truncated.
<P><B>kon</B> (k-rate note on) plays MIDI notes with current <I>kchn</I>,
<I>knum</I> and <I>kvel</I>. These arguments can be varied at k-rate. Each
time the MIDI converted value of any of these arguments changes, last MIDI
note played by current instance of <B>kon</B> is immediately turned off
and a new note with the new argument values is activated. This opcode,
as well as <B>moscil</B>, can generate very complex melodic textures if
controlled by complex k-rate signals.
<P>Any number of <B>moscil</B> or <B>kon</B> opcodes can appear in the
same Csound instrument, allowing a counterpoint-style polyphony within
a single instrument.
