Hi Ego,
There are many ways to add an external reverb to Mixbus, depending on your needs.
I often use "Mixbus 4" as my reverb bus.
First, I right-click in the black box inside Mixbus, and choose "new insert":
Now double-click on the newly-created "insert" to choose the I/O (my laptop soundcard only has 2 I/O ... of course you will need additional I/O to actually connect the stereo outboard reverb. If you have 4, 8 or more I/O connections in your soundcard, you will find them in the "System" tab. Once found, you can click on the playback" and "capture" ports to accomodate the reverb:
Вот тут был недочет:

You should then click "Measure Latency" to accomodate the latency in the I/O path. MAKE SURE THE REVERB IS IN "BYPASS" MODE WHEN MEASURING LATENCY.

Finally, you should close the dialog and "activate" the insert. If you have a 3-button mouse, you can activate/deactivate plugins, sends and reverbs using the "middle" mouse button. If you only have a 2-button mouse then you will need to use the right-click menu:
Now, to hear the reverb, you simply have to "enable" the 4th mixbus send on any track. You can use the knobs to adjust the send levels to the reverb bus.
I hope this helps!
