Hi,

I got a Bela/Beagle Bone board lately and discovered they have PD and SuperCollider installed. I consider the Bela hardware a serious alternative for the COSMO Project (instead of RPI), so I compiled non-rt Csound on it, which works. I can generate .wav files.

The next step would be that I would want to write a plugin like for JackAudio (rtjack.c) or PortAudio (rtpa.c) specifically for the Bela drivers which are not ALSA. I was wondering if any of you has written instructions about how to do this? I googled it a bit but didn't find anything, but I guess there must be something.. (Which functions need to be implemented, where to register such a plugin, how to make it a compiler option to compile against Portaudio, Jack, BELA ..)

Best wishes,

We had started work on it, but did not progress too far. There is some modification that we need to put into the code to make it run on the RT thread. It does need some knowledge of internals.

We worked on it a bit with Bernt at last year's Csound 30 in Ireland.
I don't remember what approach we took, whether we used a plugin or if
we use Csound API and grabbed the samples from the engine.  We should
ask Bernt to chime in and send out whatever we all last worked on, and
can collaborate via Github.

I have the code in my computer.

How about we create a bela branch then? (or a bela folder, whatever
works easier)

I think both actually. I'll add a directory and start a branch. We'll need to remove all locks for starters.

There was some work already to remove locking (the no-op
implementation of csoundLock and related functions in Top/threads.c),
but I seem to remember needing to comment out the messages for Bernt.
Maybe we should get rid of that notImplementedWarning altogether and
just have one message at startup to report if Csound was compiled
without threads.

Thanks for your replies. I contacted Bernt and he told me that he has a running version on his Bela but with some small problems. Creating a branch is great and if I can help I'm happy to do so (at least build and test).

Best,
Alex
