Can't adjust volume of midi tracks in mixer?

I have midi tracks with Calf Monosynth and Calf Organ on them. Everything seems to work just fine until I adjust the volume slider on the tracks in the mixer window. Nothing happens. What am I doing wrong?

re. Suppose that the plugin did expose some interface that allowed you to assign CC numbers to various knobs/sliders. In theory, would this allow the slider to work?

yes. correct.

Hi there,

Got the same problem with calf organ loaded as lv2 plugin (is lv2 plugins volume controlled by midi cc ? I would have thought it would be somewhat more low level) : volume of calf organ would not be controlled by its midi track volume fader.

I managed to work around it by creating a dedicated audio bus :

1. go to `view / buses ...`
2. select master bus
3. change its name to something else
4. press "create" button (this creates the new bus, "update" button would have overwritten master bus)
5. open mixer
6. right click calf plugin
7. in "audio" submenu, select your new bus

You now have a new bus in mixer (just next "master" output) which you can use to control calf plugin volume.

Hi there,

the qtractor changelog says (among other things) the following about version 0.9.14:


LV2 Plug-in Patch parameter/properties automation and MIDI
Controller assignment/learn are now a possibility.

Shouldn't that allow to assign those MIDI events sent by the mixer strips to any of the plug-in parameters displayed in the plugin properties dialog? (I've had no luck, though, to find any (context) menu option to initiate MIDI learning on the plugin properties widgets in version 0.9.15.)

It would really provide a much smoother mastering experience if it was possible to adjust the volume of e.g. calf synth tracks through the mixer instead of always having to open the plugin GUIs...

re. LV2 Plug-in Patch parameter/properties automation and MIDI Controller assignment/learn are now a possibility.
this are not the least related to your question: it's a LV2 specific thing (LV2 Patch properties) that were not automate-able before.

re. if it was possible to adjust the volume of e.g. calf synth tracks through the mixer instead of always having to open the plugin GUIs...
you can set one of those plugin parameters as in so called "direct-access" mode: on that a little slider will overlay the plugin list entry so that you'll have, yes, direct access to that plugin control right from the mixer strip, without having to open the plugin's own GUI (plugin > Edit); you can set once this "direct access" from the plugin's context menu (plugin > Direct Accesss > ...) or from the generic plugin's GUI (plugin > Properties...).

hth.
cheers

Ah, sorry, this apparently was a misunderstanding on my side. Although having used Linux as main OS for over 15 years, I'm still pretty new to Linux-based MIDI and audio processing. Last time I did some computer music was with Cakewalk 3 on Windows 98... ;)

That's cool, thanks for the advice!
