<U>DESCRIPTION</U></H4>
Allow precise MIDI input controller signal.
<H4>
<U>INITIALIZATION</U></H4>
<I>idest</I> - output signal <I>ictlno</I> - midi controller number (1-127)
<P><I>ictlno</I>1 - most-significant byte controller number (1-127)
<P><I>ictlno</I>2 - in midic14: least-significant byte controller number
(1-127); in midic21: mid-significant byte controller number (1-127)
<P><I>ictlno</I>3 - least-significant byte controller number (1-127)
<P><I>imin</I> - user-defined minimum floating-point value of output
<P><I>imax</I> - user-defined maximum floating-point value of output
<P><I>ifn</I> (optional) - table to be read when indexing is required.
Table must be normalized. Output is scaled according to max and min val.
<H4>
<U>PERFORMANCE</U></H4>
<I>kdest</I> - output signal
<P><I>kmin</I> - user-defined minimum floating-point value of output
<P><I>kmax</I> - user-defined maximum floating-point value of output
<P><B>imidic7</B> and <B>midic7</B> (i and k rate 7 bit midi control) allow
floating point 7 bit midi signal scaled with a minimum and a maximum range.
They also allow optional non-interpolated table indexing. In <B>midic7</B>
minimum and maximum values can be varied at krate. <B>imidic14</B> and
<B>midic14</B> (i and k-rate 14 bit midi control) do the same as the above
with 14 bit precision. <B>imidic21</B> and <B>midic21</B> (i and k rate
21 bit midi control) do the same as the above with 21 bit precision. <B>imidic14</B>,
<B>midic14</B>, <B>imidic21</B> and <B>midic21</B> can use optional interpolated
table indexing. They require two or three midi controllers as input.
<P><B>ictrl7, ctrl7, ictrl14, ctrl14, ictrl21, ctrl21</B> are very similar
to (i)midicXX opcodes the only differences are:
<UL>
<LI>
(i)ctrlXX UGs can be included in sco-oriented instruments
without Csound crashes.</LI>
<LI>
They need the addictional parameter ichan containing the MIDI
channel of the controller. MIDI channel is the same for all the controller
used in a single (i)ctrl14 or (i)ctrl21 opcode.</LI>
