This method only returns channels that have been set up using the chn opcodes right? For example, if I have an instrument that does:

instr 1 k1 chnget "test1" k1 chnget "test2" k1 chnget "test3" endin a call to csoundListChannels() still returns 0. My question is, is there any way I can retrieve channels without having to define them using the chn opcodes? And related to that, how does chnget work when no channel has be previously defined. Does it create the channel if it's not already found? Would run a performKsmps() and then calling csoundListChannels() retrieve the channels? |

Maybe the channels have not yet been created, you need to set them to make them
pop into existence. Getting something from a non-existing channel is probably not making the channel be created (I am assuming, without looking at the code).

So it's the call to SetChannel() in the API that likely creates the channel when they have not been defined in the orc? On 22 October 2016 at 17:05, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:

or a chnset in the orchestra, I'd say.

I guess there is no eloquent way of finding the number of channels without using a combo of the chn opcodes and csoundListChannels. I was hoping to develop a way of creating generic GUIs on the fly based only on the chnget's used in an orchestra. Apart from parsing the orchestra myself, do you have any suggestions? At the end of the day, I guess declaring them in instr 0 is not such an ordeal. On 22 October 2016 at 18:27, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:

I would not think so.

The chn opcode it is then. On 22 Oct 2016 19:15, "Victor Lazzarini" <Victor.Lazzarini@nuim.ie> wrote:
