Description

Allow precise MIDI input controller signal.

Initialization

idest - output signal

ictlno - MIDI controller number (1-127)

ictlno1 - most-significant byte controller number (1-127)

ictlno2 - in midic14: least-significant byte controller number (1-127); in midic21: mid-significant byte controller number (1-127)

ictlno3 - least-significant byte controller number (1-127)

imin - user-defined minimum floating-point value of output

imax - user-defined maximum floating-point value of output

ifn (optional) - table to be read when indexing is required. Table must be normalized. Output is scaled according to max and min val.

Performance

kdest - output signal

kmin - user-defined minimum floating-point value of output

kmax - user-defined maximum floating-point value of output

midic7 (i- and k-rate 7 bit MIDI control) allows floating point 7 bit MIDI signal scaled with a minimum and a maximum range. It also allows optional non-interpolated table indexing. In midic7 minimum and maximum values can be varied at k-rate. midic14 (i- and k-rate 14 bit MIDI control) do the same as the above with 14 bit precision. midic21 (i- and k-rate 21 bit MIDI control) do the same as the above with 21 bit precision. midic14 and midic21 can use optional interpolated table indexing. They require two or three MIDI controllers as input.

ctrl7, ctrl14, ctrl21 are very similar to midicXX opcodes the only differences are:

• ctrlXX UGs can be included in score oriented instruments without Csound crashes.
• They need the additional parameter ichan containing the MIDI channel of the controller. MIDI channel is the same for all the controller used in a single ctrl14 or ctrl21 opcode.

Deprecated names

The opcode names imidic7, imidic14, imidic21, ictrl7, ictrl14, and ictrl21 have been deprecated in Csound version 3.52. Instead use imidic7, imidic14, imidic21, ictrl7, ictrl14, and ictrl21, respectively, with i-rate outputs.
