Until very recently - I’m not sure which Cubase 10 version, the wave form that is displayed in the automation area (volume for example) accurately updates/changes depending on which Lane is chosen from a multi-lane channel.
Now all that happens is that the automation area shows ALL wave forms from all Lanes.
Previous versions of Cubase (since lanes came in) had correct display - only since one of the updates in Cubase 10 did it stop displaying correctly.
The time it’s taken to get from you reporting it to Steinberg to still having no solution (and seeing all waveforms is absolutely not helpful when drawing automation) is pretty frustrating. I know they haven’t listed it in the bug fixes, but I can’t believe that they haven’t even addressed it.
I have just tried in Cubase 10.0.5 (the very 1st 10.0.x public release) and Cubase 9.0.40 (last Cubase 9.0.x release). It looks the very same in all these versions.
Yeah I can absolutely recall it working perfectly, but I don’t know which version and don’t keep old versions on my machine.
In any case - whether it worked or not is probably irrelevant … it shouldn’t display an overlapping multi-wave form in the automation area. It means you can’t accurately plot stuff.
