midinoteonoct midinoteonoct midinoteonoct Gets a MIDI note number value as octave-point-decimal value. midinoteonoct is designed to simplify writing instruments that can be used interchangeably for either score or MIDI input, and to make it easier to adapt instruments originally written for score input to work with MIDI input. In general, it should be possible to write instrument definitions that work identically with both scores and MIDI, including both MIDI files and real-time MIDI input, without using any conditional statements, and that take full advantage of MIDI voice messages. Note that correlating Csound instruments with MIDI channel numbers is done using the massign opcode for real-time performance,. For file-driven performance, instrument numbers default to MIDI channel number + 1, but the defaults are overridden by any MIDI program change messages in the file. midinoteonoct xoct, xvelocity xoct -- returns MIDI key translated to linear octaves during MIDI activation, remains unchanged otherwise. xvelocity -- returns MIDI velocity during MIDI activation, remains unchanged otherwise. If the instrument was activated by MIDI input, the opcode overwrites the values of xoct and xvelocity with the corresponding value from MIDI input. If the instrument was NOT activated by MIDI input, the values of xoct and xvelocity remain unchanged. This enables score p-fields to receive MIDI input data during MIDI activation, and score values otherwise. See the MIDI interop opcodes section for details on adapting score driven instruments for MIDI or vice-versa. Here is an example of the midinoteonoct opcode. It uses the file midinoteonoct.csd. See the sections Real-time Audio and Command Line Flags for more information on using command line flags. Its output should include lines like: i1 8.00000 i1 9.33333 midichannelaftertouch, midicontrolchange, mididefault, midinoteoff, midinoteoncps, midinoteonkey, midinoteonpch, midipitchbend, midipolyaftertouch, midiprogramchange Author: Michael Gogins Example written by &namekevin;.
