Summary0007254: "Add new subgroup bus" is not working
DescriptionThe feature to add a track group submix bus is a very nice feature and saves a lot of time, but unfortunately, it harqdly ever works for me.

Usually when I use that option nothing happens. In the past version of Ardour I think it even caused me some crashes.

Currently I'm just unable to use it.
I create a track group, I select the "Add new subgroup bus" from the context menu and nothing happens.

Can anybody confirm this behavior?
Additional InformationI'm running official stable 5.6 from the main Ardour downloads.
TagsNo tags attached.

it works just fine.

e.g. 38seconds into
or (official 5.6 build)

Can you provide more information and a recipe? Are there MIDI tracks in the group or audio-tracks with different number of outputs in the same group?

In both cases an error message would be displayed (Window > Log) and the error button start blinking red.

Ardour 5.6 64bit (Gentoo)

Works for me when I:

- Create a new session
- Create 4 mono tracks
- Create a new group from tracks 1 and 2 by dragging in the edit window on the left side of the track headers.
- Click with left mouse button on group indicator on the left side of track headers, select Add New Subgroup Bus.

Result: A new stereo bus is created and track outputs (in the group) are sent to the input of the Bus.

This was on a "clean" session maybe the problem appears only on more complicated sessions ? Might be connected on the usage of another feature ?

The session I experienced this in had 4 MIDI tracks that I grouped and wanted to create a subgroup bus for. All had ZynAddSubFX instrument plugin and fed stereo audio signals to Master bus.

so you should have received a

  [WARNING]: You cannot subgroup MIDI tracks at this time

Did you get that?

It seems to me like two options to solve/improve this issue would be to either present a more obvious error dialog or perhaps preferrably only have menu entries in the group tabs context menu that are applicable.

x42: I didn't see any warning.

I tried now and after opening the Log window - I found this:

"You cannot subgroup MIDI tracks at this time"

So - it'd be fantastic if I could :) Becasue I create submixes for synthesized drumkits all the time, so that'll save me a lot of time.
