Modulators - not available on subchannels

Hi, maybe I miss something… Seems impossible to use modulators (Cubase 14) on subchannels (in my case Maschine additional outputs) and on the plugins used on these channels.
Only workaround is to route them into a group track, where the modulators work as expected.
Any idea? Or is this a bug?

I found that they don’t work on individual instruments in Halion or UVI Workstation. Only on Instrument channels.

I have the same thing.

I’d like to hear from Steinberg on this.
Martin? What’s the deal with a ‘multi-timbral’ rack instrument and the modulators?

Me too… Please!
