getftargs

Fill a string variable with the arguments used to create a function table at k-rate.

Plugin opcode in getftargs.

getftargs runs both at initialization and performance time.

Syntax

Sdst getftargs iftno, ktrig

Initialization

ifno -- Number of the table whose arguments we want to request.

Performance

Sdst -- output string variable.

ktrig -- trigger signal, should be valid at i-time. The output string variable is filled at initialization time if ktrig is positive, and at performance time whenever ktrig is both positive and different from the previous value. Use a constant value of 1 to print once at note initialization.

Examples

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

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac      ;;;realtime audio out
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o getftargs.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 44100
ksmps = 32
nchnls = 2
0dbfs  = 1

instr 1
Sargs getftargs 1, 1
puts Sargs, 1
endin

</CsInstruments>
<CsScore>
f 1 0 1024 "quadbezier" 0 0 0.5 200 0.8 450 0.33 600 0.1 800 0.4 1024 0
i 1 0 1
e
</CsScore>
</CsoundSynthesizer>

Its output should include this line:

0 0 0.5 200 0.8 450 0.33 600 0.1 800 0.4 1024 0
