Hello,
I would like to ask you some explanations about the new UDO syntax.
In a UDP / OSC context, I send to Csound just simple messages as “/csound/event …” or “/csound/channel/…”.
This csound code works well:
<CsoundSynthesizer>
<CsOptions>
-odac --port=7777
</CsOptions>
<CsInstruments>sr = 44100
ksmps = 128
nchnls = 2
0dbfs = 1gisquare ftgen 2, 0, 16384, 10, 1, 0 , .33, 0, .2 , 0, .14, 0 , .11, 0, .09
opcode setget, k, i
pfield:i xin
chnidx:S = sprintf"%\.02f\_p%d", p1, pfield
fieldvalue:i = pindexpfield
chnsetfieldvalue,chnidx
value@global:k = chngetchnidx
xoutvalue
putschnidx, 1
endopinstr 1
asig = oscilsetget\(5, setget4, 2)
outs asig*asetget\(6), asig*asetget\(6)
endin
For example, send a /csound/event "i1.01 0.0000 15.0000 51.0000 0.3390 1.0000” message provide a new instance of i1, and send after that for example a /csound/channel/1.01_p4 [val] massage control the setget4 parameter / pfield associated. No Csound console warning such as "i1 uses 6 pfield but etc." too.
But you can see the opcode setget uses a mix of old and new syntax.
When I try to follow the new Csound 7 syntax approach this causes some errors and makes my mind noob again.
Indeed, when I try to send the same messages with this udo:
opcode setget2pfield:i:k
chnidx:S = sprintf"%\.02f\_p%d", p1, pfield
fieldvalue:i = pindexpfield
chnsetfieldvalue,chnidx
value@global:k = chngetchnidx
xoutvalue
putschnidx, 1
endopCsound receives an error. I’ve tried to write the udo otherwise but in vain…
I’m pretty sure that my misunderstanding of some basis causes this post.. So...
Thanks for your help Professors friends composers and others!
