@zwizwa:matrix.orgTom SchoutenHello everyone. I'm a long time Pure Data user + use Jack for some custom code and sometimes Ardour. Recently started moving all my PCs to NixOS, and have one main studio PC running Debian + single user Nix11:52:49
@sjfloat:matrix.orgsjfloat👋11:54:00
@sjfloat:matrix.orgsjfloatI'm actually at the precipice of writing a pd external, so I may pick your brain about that.11:55:47
@sjfloat:matrix.orgsjfloatI'm considering abandoning pipewire and going back to a modal pulseaudio/jack arrangement, suspending PA when I want to start jack.11:58:52
@sjfloat:matrix.orgsjfloatIOW, the way I did it for years on Debian 11:59:43
@zwizwa:matrix.orgTom Schouteni don't rember how but there is a way to disable an interface in pulseaudio via some dbus call, though i never got that to work reliably... i just kill pulseaudio before starting jack. on the dedicated pc pulseaudio is not running.12:12:16
@zwizwa:matrix.orgTom Schoutenre: pd externals. sure just ask. it's been a while though for me but i don't think much has changed12:12:43
@sjfloat:matrix.orgsjfloat PA provides a pasuspend command. I generally just added to my startup and shutdown scripts for jac. 12:45:22
@sjfloat:matrix.orgsjfloat* PA provides a `pasuspend` command. I generally just added to my startup and shutdown scripts for jack.12:45:45
@sjfloat:matrix.orgsjfloatThis arrangement worked for me under NixOS only briefly, a few years ago. I've never been able to reestablish that since.12:47:29
@sjfloat:matrix.orgsjfloatGenerally, I want things like pulseaudio in my system config, but not jack.12:48:39
@sjfloat:matrix.orgsjfloatAnd since switching to pipewire, I've had terrible performance issues with chrome (it's an older machine).12:49:20
@sjfloat:matrix.orgsjfloat I do have a lot more jack-dependent things working again now, though. 12:49:57
@sjfloat:matrix.orgsjfloatI also introduced the Alsa Modular Synth to the nix pkgs. This was probably my favorite softsynth for years.12:50:55
@sjfloat:matrix.orgsjfloatBut I'm paying more attention to Pd now. I'd like to create Pd objects using Faust.12:51:57
@sjfloat:matrix.orgsjfloatAnd possibly csound12:52:22
@sjfloat:matrix.orgsjfloatThe external I want to write now, though, is one for handling MIDI events, which feels pretty clumsy to me in Pd.12:53:22
@zwizwa:matrix.orgTom Schouteni just tried starting jack & pd while pulseaudio was running and it worked without manual intervention - it seemed to just disable the port automatically. then stopping jack & pd and pulseaudio (tested in firefox) was working after. this is nixos unstable from a couple of months ago20:37:55

are you thinking about interfacing with midi device directly from your external?
20:40:36
@sjfloat:matrix.orgsjfloat No, I'll probably just feed it what I get from notein or some other provided object. 20:41:46
@sjfloat:matrix.orgsjfloat Actually, I'm looking at the code for notein for guidance. I didn't find the HOWTO very helpful. 20:42:39
@sjfloat:matrix.orgsjfloatBut maybe there's an existing external you know of that would do what I want.20:43:48
