Hello,

I need an explanation before installing this update please :

15.0.30 Edit group : “when using the Comp tool in an Edit Group, collapsed lanes are no longer affected”.

Does it mean that in a 12-tracks drums in an edit group, we have now to display the 12 tracks lanes to edit them with the comp tool properly?

4

Good point. The release note should actually be:

When using the Comp Tool with Group Editing enabled, comping operations are now correctly applied to collapsed Lanes on all tracks in the group.

I’ll get it changed on the release note page asap.

Hello,
Could it be possible to increase the number of physical tracks/connections from 256 to 384 or even 512?

Thanks a lot.

12 years ago I was “thrown out” of the forum for bringing this up (under a different user name). Well yes, it may have been a bit loud conversation.
This has been brought to your attention several times (also under my current user name), and I have several times after that provided a “workaround”.

It took at least 12 years… But hey, in fear of being to early out… Congrats to all of us for you to finally fixing this big BIG workflow killer.

Cubase 15.0.30 Release Notes/MIDI Remote and Controller Support says “Cubase now supports MIDI Remote API 1.3”

I thought previous versions of Cubase 15 were already supporting it.

Can you confirm that the v1.3 was not supported before? Or maybe something has changed in the api?

Any clarification would be very welcome!

  • Sampler tracks now reference the correct audio files when resolving missing samples.

Many people will be happy about that if it fixes what I think it fixes…

I know I keep repeating myself, but has there been any change to the mousewheel behavior in the sample editor sample selection dropdown menu (I am referring to Cubase 13/14: Quickly switching between samples in sample editor not possible which applies to Cubase 15 AFAIK)?

I know there is some workaround using keyboard shortcuts… but it’s still not quite the same behavior to me.

…ducking away…

10

1.3 was available from 0.20 already.

11

Yes, what you say is correct. But including this sentence in the release notes may not be a mistake, and something has changed. At least it makes me doubt…

12

Bug fixes here and there, perhaps minor ones, are always possible. No change on the surface though. I’d knew, since I always compare js/ts definitions with the previous ones. And since @Jochen_Trappe already posted the 1.3 details from April, then a few days later, I even posted examples using 1.3 (in CB15.0.20) I see no reason to have doubts.

I want to thank you for repairing the left click right option tool!!!

scrolling is still way too fast on Mac version. If using non-apple mouse.

any reason this is being ignored for such long time ?

Steinberg, why is your software testing so generally lacking? Seriously, it’s getting so very old.

I uninstalled & reinstalled Download Assistant; made no difference.

PC or MAC i haven’t installed yet reading the forum and about to read the release notes

17

I’m getting the same error when trying to update Halion just now, too! Something is seriously broken, Steinberg.

18

Mac or PC for those that haven’t installed?

19

It’s Mac, as you can probably tell from the dialog box screen grab.

I used Claude to figure out what happened: Steinberg Download Assistant and helper daemons are not surviving minor MacOS updates. In this case, a few days ago I updated from 15.7.3 to 15.7.7. This is a real problem! Even worse, the dialog claims the error is “unknown”, but it absolutely is and is right there in the SDA logs! This really is unacceptable, Steinberg. Do not feed us useless error dialogs, it’s uncouth af!

Here is the fix Claude came up with:

Do this, in order, in Terminal

# 1. Clean any stale registration, then register fresh
sudo launchctl bootout system /Library/LaunchDaemons/com.steinberg.SilentInstallHelper.plist 2>/dev/null
sudo launchctl bootstrap system /Library/LaunchDaemons/com.steinberg.SilentInstallHelper.plist

# 2. Confirm it's alive — this must print a service block, not "Could not find service"
sudo launchctl print system/com.steinberg.SilentInstallHelper | head

No need to use Terminal. Just another example of bad AI webscraping…
