[ALTERNATIVE FOUND] "Connect" opcode doesn't work in Cabbage2

#1

Hey Rory,
I’m trying to test the connect opcode of CSound but even when I copy&paste the example (http://www.csounds.com/manual/html/connect.html) Cabbage tells me that I forgot a variable name…
But I can’t find what I missed, so I think it’s a big

I’m trying to use connect to virtually connect a Cabbage effect after a Cabbage Synth, (like you would do in a daw) maybe it’s just not the way it works ?

Thanks in advance for your help !

That’s odd, maybe those opposed aren’t included with that version of Csound. It’s quite easy to do this without the connect opcode. Using audio rate chnset/chnget opcodes will give your the same thing and more. Let me know if you can work it out. Otherwise I can try to put together a simple example one I get back from my travels.

Alright, I gave it a try and it doesn’t work as expected :

  • It successfully connects the two intruments, BUT I tried with a reverb and the sounds plays endlessly unless I set ksmps to 1 (It’s set to 256 usually, this provide a good compromise with memory usage)
  • I can’t play 2 notes of the same instruments through my reverb

I can provide a quick example if you want, what I really want to achieve is to set, say, a reverb after my main instrument and I’d like it to act the same way as it is when I set the Cabbage reverb after my synth in my DAW

I actually would like to include the Cabbage reverb example in my synth if it’s more clear

Any clues ? Thanks for your help !

Thanks for your quick reply ! I tried with chnset / chnget but didn’t know about the chnmix opcode !
I’ll try this as soon as I come back from my vacation but I’m almost sure it will do as expected !

EDIT : Thanks so much it works perfectly :wink:
