Hi,

Is it posibble to run pd without gui, without any window?

I need it, because I found out the graphic rendering eats lots of cpu. I'd like to run "pd -jack -rt --no-gui -open /some/file" and record the track in a linux launched in text-mode. I won't use any sliders or bang buttons, I just need my patch to run in background and transform midi input to audio output.

Yea, I know it sounds very funny, but no matter why do I need it, just: Is it possible to run puredata like that?

yes: pd -nogui

This leads to another question. I know that having updating number boxes and graphics bangs will slow you down but is it still a performance issue to have a complex GUI displayed in PD if it isn't being updated?

yeah i always wondered stuff like that too.

also, if you use send and receives inside of gui objects, do they still get sent when running gui-less?

@ClaudiusMaximus
Thanks a lot, I wonder why I couldn't find it as it is mentioned in 'pd' usage.

@ZombieControl
I guess the graphics are recalculated from scratch in each dsp loop. Well, if I am right, it's a giant performance issue.

@hardoff
Yes, it does send messages, I've already checked it. What's more, the only way I found to turn audio processing on was to put a [loadbang] ---> [; pd dsp 1( on a patch I open, as you cannot control anything in this mode.

========================
And one more question: I cannot manage to use alsa-midi from command line.
I use:
pd -jack -alsamidi -nogui -open /some/file
but I still cannot see puredata in Jack Control 'Connections' window.

How do I start alsa-midi (same as if I chose menu Media->ALSA-MIDI and left default settings) when running pd from command line and w/o gui? (and using Jack)

I use:
pd -jack -alsamidi -nogui -open /some/file
but I still cannot see puredata in Jack Control 'Connections' window.

Same problem here. I use
pd -jack /some/file.pd but pd won't show up in the Jack Control Connections window. When I change to ALSA manually after pd launched I get an error (obviously) since Jack already uses the alsa output. After changing back to Jack in pd it suddenly works.

Another question: how can I set "audio ON" straight from the command line?

-jack -channels 2 -alsamidi -mididev 1 -send "pd dsp 1"
