Description

pcount returns the number of pfields belonging to a note event.

Syntax

icount pcount

Initialization

icount - stores the number of pfields for the current note event.

	Note
	Note that the reported number of pfields is not necessarily what's explicitly written in the score, but the pfields available to the instrument through mechanisms like pfield carry.

Examples

Here is an example of the pcount opcode. It uses the file pcount.csd.

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
; Audio out   Audio in   No messages  MIDI in
-odac           -iadc    ; -d         -M0  ;;;RT audio I/O with MIDI in
; For Non-realtime ouput leave only the line below:
;-o pcount.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>
;Example by Anthony Kozar Dec 2006
instr 1
    inum  pcount
    print inum
endin

</CsInstruments>
<CsScore>
i1  0 3 4 5       ; has 5 pfields
i1  1 3           ; has 5 due to carry
i1  2 3 4 5 6 7   ; has 7
e
</CsScore>
</CsoundSynthesizer>

The example will produce the following output:

SECTION 1:
new alloc for instr 1:
WARNING: instr 1 uses 3 p-fields but is given 5
instr 1:  inum = 5.000
B  0.000 ..  1.000 T  1.000 TT  1.000 M:      0.0
new alloc for instr 1:
WARNING: instr 1 uses 3 p-fields but is given 5
instr 1:  inum = 5.000
B  1.000 ..  2.000 T  2.000 TT  2.000 M:      0.0
new alloc for instr 1:
WARNING: instr 1 uses 3 p-fields but is given 7
instr 1:  inum = 7.000
      

The warnings occur because pfields are not used explicitly by the instrument.
