Re: Installing Jack on RPI3

I want to update this thread because I kept coming across it trying to find an answer through google, and I imagine other people get caught up in the same circle. Jack2 in the default repository uses dbus and will fail to run on a headless pi. Previously, that Autostatic repository was how you insta...

Re: Setting taskset/cpu affinity of whole audio stack (ALSA kernel module, lib, USB/gpio IRQ's)

I’ll just update this, in case someone else has the same goal. Hardware interrupts are defaulted to core 0 with arm cpu’s. You can’t really move them around (maybe with the RT patch). For me, it worked best to isolcpus=2,3 and taskset jack and Pure data to those. Jack2 can use multiple cores(taskset...

Setting taskset/cpu affinity of whole audio stack (ALSA kernel module, lib, USB/gpio IRQ's)

So I know you can use taskset to set the cpu affinity of user-space processes. For real time audio in my case (using isolcapus and taskset), that would be Jack audio server and Pure data. The problem is, Jack runs on top of ALSA, and I need the ALSA kernel module and Alsa-lib to be on the same isola...

Re: STICKY: Introduce yourself!

Hello, My name is Anthony and I'm a musician that's working on my first Pi project. I'm building a musical pi thing. Not sure of what to call it exactly, but it'll function as a Midi Fighter style instrument with Sanwa arcade buttons, and as a DAW, effects processor, looper, and so on. Anyways in do...
