The best way I have achieved this in Cubase 11 is to take the audio of the loops and make Sampler tracks from them. Then play those sampler tracks from a pad that can be set to toggle the midi note.
Instead you could set it up in Groove Agent. You have to put the audio in a GA Instrument pad, and make the Performance pad have a single 4 bar note which triggers the Instrument pad with the sample on it. You can put the midi in a performance pad and route that midi out to the drum instrument, but you have to do that on a different “agent” than where you put samples.
In the end, (without a template set up for this purpose) it’s easier to copy paste into a different set of tracks used for looping ideas. I have a very elaborate setup using pre-configured Sampler tracks, for this purpose.
And this is exactly why we could really use a clip launcher in Cubase!
I intend to share my complete template soon if that would have any interest. Between making music, and instructing, and my day job, I just haven’t gotten around to it.
