Route from VLC to MODEP

Patchbox OS
1

Hi guys,
I am trying to route an audio from VLC to MODEP using QJackCtl with no luck!

Any tips?

2

Is VLC set up to use Jack backend? What’s the output of jack_lsp -A when VLC and MODEP are running?

Thanks Giedrius, sorry but I am a newbie!

VLC setted as Jack audio output

The output jack_lsp -A is:

system:capture_1
   alsa_pcm:hw:pisound:out1
system:capture_2
   alsa_pcm:hw:pisound:out2
system:playback_1
   alsa_pcm:hw:pisound:in1
system:playback_2
   alsa_pcm:hw:pisound:in2
system:midi_capture_1
   alsa_pcm:Midi-Through/midi_playback_1
   Midi-Through:midi/playback_1
system:midi_playback_1
   alsa_pcm:Midi-Through/midi_capture_1
   Midi-Through:midi/capture_1

   pisound:midi/playback_1
system:midi_playback_2
   alsa_pcm:pisound/midi_capture_1

   pisound-ctl:midi/capture_1

But maybe I am missing something in MODEP? I attach a screenshot

Well, it seems it works through Patchage but I have stills some doubts:

  1. I have to route VLC to the single effect: this means if I would like to add a second effect in my board I have to route in Patchage to create a chain of the effects.
    Does it work in this way or is there any chance to route VLC to all the pedalboard, so I can add stuff without update the routing everytime in Patchage?

  2. If I route VLC to effect1 and system playback1 I have 50% of wet (from the stompbox) and 50% dry (from VLC) output.
    If I route VLC just to effect1 the audio playback is only with the stompbox effect on (100% wet), stompbox button off = no audio
    Can I use the button of the stompbox WET/BYPASS?
    Still missing something?

The MOD UI shows only hardware ports on the left hand side, so it won’t show any other software’s connection ports.

I’d recommend placing some simple Gain pedal (like Tiny Gain), as your very leftmost pedal, and hook up VLC to that pedal (if the gain pedal is mono, then just use 2 instances, one for each channel), then you should be able to just build a chain of effects towards the right, and to the output. Use gain or some mixer pedal to mix the signals as needed.
