Hello all,
Has anyone been using csound with -+rtaudio=jack while using pipewire
as their jack backend? I've found that it leads to some weirdness,
including not playing back sound at all sometimes (this was happening
in non-predictable ways). Also, it seems to require the -B buffer size
to be 2048 for my machine, even though pw-top says it's running at
1024 as its buffer size.
Csound has been working great using -+rtaudio=pulse, but when I want
to use it for live midi stuff, I definitely will need to use the
-+rtaudio=alsa, or -+rtaudio=jack for that lower latency.
Thank you again for your help,
Brandon Hale
I've been running it on the church organ for a few months now. I
had
weird problems with Jack2, and thought to give
pipewire a go at handling it. Since then I've had no hangups, and
everyone is happy.
I'm only using Csound as a mixer, as the organ has 7 output channels,
but we only have 5 speaker cabinets. It reads in
the 7 channels from GrandOrgue, and passes various combinations, (chosen
by our organist, not me) and feeds the resulting
sounds out on the 5 output channels for amplification and output to the
speakers.
I don't have the parameters to hand, I think we're running at 1024.
There were a few problems getting GrandOrgue to work with
pipewire-jack, mainly caused by having both the jack and pipewire-jack
libraries, eventually got rid of the original jack2
ones, then it all behaved pretty well.
