Dear devs!

I just browsed the csound api examples for cpp, and the README refers to 12 examples but there are only 6 included. What I really was after was an example (to send to some colleagues who, unlike me, are actually programmers) of how to use set/getchannels and how to use performksmps to allow manipulation of the data coming from these channels in their own software in a timely manner.

Is there such an example?

Regards,

Anders

I can put together an example for you later.

Should you show up in Sweden, unannounced or not, I'll make emergency calls to 

1. The department of nuclear physics at Gothenburg University.

2. My friend Nils who is an excellent homebrewer (as in beer, not the osx kind) to comission a keg.

I am sure we can find fallout shelter for the Hawking radiation in e.g. Norberg:

I just pushed an example that uses SetChannel() to here:

https://github.com/csound/csoundAPI_examples/blob/master/cpp/example7.cpp

Is this what you were looking for? SetChannel() can be called anytime. It's thread safe so you don't have to worry about calling it between k-cycles.

That's great, thanks!

What I (or my hacking wizard colleagues) want to do is to use performksmps in order to ensure proper sync to other processes.
We want to use several control channels (e.g. frequency, pitch, filter cutoff etc) to affect what is being done in csound, and use several channels (well, more than one at least) of the resulting audio and mangle further in our applications before sending off to yet other appications handling the output to the sound card.

I suppose that if we set odac to dummy, use Set/GetChannel for audio and use performKsmps for timing we should be alright?

Anders

Ah I see. I wouldn't bother using channels for the audio. It's probably better to send audio to and from Csound using the input/output buffers. The problem with creating an example for that is the need to add a custom IO interface. But let me see what I can do. I think I have an example some place that might be useful.

Well, we are using OpenAL for output, so we just need to transfer audio from csound buffers to OpenAL buffers (and update positions for sound sources in OpenAL space) for each kspms cycle, so the IO is no problem.

i get the strong impression that sweden is a major candidate for one of the next csound conferences ...

Thank you again, Rory, for these excellent examples!

We now have something working as proof of concept.

OpenAL has a system where you queue one or (rather) several buffers for playback, attached to a 'source' that can be moved around in space. When a buffere has been processed by OpenAL it is removed from the queue, and so by asking via the OpenAL api how many buffers are still queued, and running the required number of iterations of performKsmps as soon as one buffer is found released from the queue seems to sync things up nicely.

One additional thing I'd like to ask, though. In our csd we use the OSC opcodes to receive exernal control signals. When using the csound api I suppose we need to link to the OSC opcodes somehow to get this to work. Is there a simple way to do so?

Regards,

Anders

You don't have to do anything special to get the OSC opcodes to work. The Csound library will search OPCODE6DIR64 on startup and load all plugin opcodes it finds.

Brilliant, thanks!

Is there btw any way to check if OPCODE6DIR64 is already set and if not, set it to some path via the api?

You can check for the existence of the OPCODE6DIR64 variable in your system path. There are API methods called csoundSetGlobalEnv() and csoundGetGlobalEnv()

https://csound.github.io/docs/api/group__MISCELLANEOUS.html#ga0183dad9bbc4961d66a280e5292091ed

I've never used them. On Windows I just use getEnv() and setEnv(). And it's not something I've ever had to do on OSX or Linux. Alternatively you can just pass the plugin library directly to Csound in your CsOptions section using --opcode-lib=LIBNAME.
