Summary0006267: Gain increse in monitoring when using auxiliar send to another bus while recording.
DescriptionOk, not sure if exactly a bug or something strange with my routing, wanted to test out Ardour4, it's been a while since I've used it since now I have been using more Mixbus. Will explain what I'm doing by steps:

1) Create a mono bus for guitar
2) Create a mono track for same guitar
3) Create Stereo Bus for reverb (Calf Reverb)
4) Create aux buses on both guitar mono bus and track and send 0 DB signal to stereo bus with reverb (similar to Mixbus bus sends)
5) All sounds fine during normal monitoring
6) As soon as I engage and start tracking (only as it rolls) I hear an increase of gain in the monitoring sound just as if I had Ardour doing the monitoring, but I don't, I have Hardware monitoring by my sound device in preferences, doesn't affect the track at all. If I stop rolling but record buttons engaged monitored sound goes back to normal levels.

I already tried putting the aux either pre or post fader, same results.

So am I doing (routing) something wrong or is it a bug?

Thanks!

This is mysterious. I cannot reproduce this. (using a test-signal feed into the "guitar" track and bus).

Either way, with Preferences > Audio > Monitoring set to 'ardour' it should be the other way 'round (signal is be attenuated) because the monitor switches from "In" to "Disk" with play/stop.

Just to confirm: Preferences > Audio > Monitoring
   Record Monitoring handled by: ardour
   Tape machine mode: off

The guitar-track and guitar-bus' outputs are connected to master; as is the output of the stereo effect bus.
The stereo effect bus has its input disconnected and only receives signals via the aux-sends.

Is that correct?


PS. mixbus does not connect the individual track output. Ardour does this by default.

curious. What is the use-case of such a routing setup (feeding a bus AND track with the same input)?

Sorry for my delay to reply. I am at the moment away from my home and will not be back until sometime mid next week.

You ask:

"The stereo effect bus has its input disconnected and only receives signals via the aux-sends."

I am absolutely sure that the input is disconnected, I'll also confirm the preferences when I get there and will let you know.

Thanks!

Ok, now that I am back I can confirm:

My preferences are Recording monitoring: Audio Hardware
Tape Machine: Off

Outputs of Bus and Track are connected to Master, but also have that send to the Stereo Bus with Reverb. I do this so I can decide how much of the signal goes to the reverb bus (it's a mix of dry and reverbed signals).

I can confirm that with those settings, as soon as I start rolling (track engaged) and recording the gain increases.

That's just what I find kind of weird, I don't know if this is supposed to be this way, I don't know if it's a bug or not. Maybe it's kind of useful to hear the active track while recording it by making it sound louder for monitoring purposes. The track is not recorded with that gain increase. So should we see this as a "bug"?

I just found it weird, that's all, personally, I can live with it, as long as it doesn't affect the recorded signal/file...
