Re: [Csnd] Csound on Bela with Trill

Hey all,
Have just tried to use the trill opcode but bela is not recognising it - I have just updated its software too. Any idea what the issue could be? Thanks

Ryan

Hi Ryan!

It should be included in the latest version of Bela. At least Dr. B got it to work with his students as far as I know with the latest version. It would be helpful to see the reported error. Can you send the printout of the console?

Thanks for the reply Bernt - attaching an imagine of the full console output. I am using the exact code from the csd attached earlier in this thread. Appreciate it!

Dear Bernt,
I had the same experience as Ryan with the trill opcode.
After making an update from Bela I was expecting to have also the csound updated but the csound version is the same from the March 2020. Actually, from this site we can see the csound code is not updated since more than one year. How did you get the trill opcode to work? Is there another source to update bela?

Hi! The trill opcode is not in the csound.h file, so that date doesn’t matter really. As far as I know Bela are pulling from the Csound repo when building a new version, but I don’t know why it hasn’t been updated with the latest Csound for Bela code. I’ve emailed them and asked now.

In the meantime, you can make a C++ project on the Bela and use the Csound for Bela-cpp file which is in the Csound repository: https://github.com/csound/csound/blob/develop/Bela/main.cpp

Bela will be updated with Csound 6.15 soon (which includes the trill opcode), but in the meantime you can download and install 6.15 from here: https://github.com/giuliomoro/csound/releases

Make sure you’ve updated the Bela code first (https://learn.bela.io/using-bela/bela-techniques/updating-bela/) and then copy the file over to the Bela board and run sudo dpkg -i csound-6.0.0-Linux-bela5.deb

The primary source for documentation of Csound on Bela can be found on their learning site: https://learn.bela.io/using-bela/languages/csound/. I will update it with the trill example once the official update comes out

Thank you so much Bernt! I’ll let you know as soon as I installed it.
Best,
Luís
