New Dorico 5.1.21.2098 user here… finding and understanding correct routing of Kontakt 7.1.8 outputs is difficult.
Kontakt 7 has a flexible output configuration system. It’s possible to create many either mono or stereo outputs or combinations of each and route Kontakt-hosted instrument plugin outputs though these outputs. I haven’t yet found a similar way in Dorico to configure the Dorico mixer inputs and it’s taken me a while to figure out how Dorico is accepting Kontakt outputs.
Initially, I set up Kontakt to output a stereo output for each instrument, assuming that each of these stereo signals would appear at a single Dorico mixer input (which I assumed to be stereo inputs). For example, with four Kontakt-hosted instruments, Kontakt would provide four stereo outputs labeled Output 1/2, Output 3/4, Output 5/6, and Output 7/8, resulting in eight mono outputs grouped into four stereo outputs. Dorico then responded with four mixer inputs as expected,
However, when playing only instrument #1, both mixer channel #1 and channel #2 mixer meters showed stereo signals (two meter bars in each channel) . In addition, when the first instrument pan control (NOT the mixer pan control) was set to full left, only the channel #1 meter showed a stereo signal, and when the first instrument pan control was set to full right, only the channel #2 meter showed a stereo signal (or what I thought were stereo signals at the time).
When playing only instrument #2, the same happened as in the above paragraph except with mixer channels #3 and #4.
When playing only instrument #3 or #4, the Dorico mixer did not respond with a signal. (no meter response on any of the four mixer channels).
The above behavior led me to wonder if each Dorico mixer channel was only receiving a mono signal - that is, in my configuration, Dorico acted as if it received only stereo outputs labeled Output 1/2 and Output 3/4. In other words mixer channel #1 received only the instrument #1 left channel, mixer channel #2 received the instrument #1 right channel, mixer channel #3 received the instrument #2 left channel, and mixer channel #4 received the instrument #2 right channel. The outputs from instrument #3 and #4 were lost altogether.
I have tried the same tests with instruments from both Native Instruments and Chris Hein - same behavior.
It appears that the Dorico mixer will not accept stereo outputs from Kontakt 7 - hosted instruments, unless there is a way to modify the mixer behavior that I’m not yet aware of.
The solution I’ve settled on is to accept that I can’t use stereo outputs and then configure Kontakt and its hosted instruments for mono outputs only. As an example for the above configuration with four hosted instruments, I choose from the Kontakt Outputs panel,
Presets / Batch Configuration > Factory > Mono 4x,
to configure four mono outputs. I could then check each instrument output individually to insure that it’s mono output is set to the desired Kontakt output, but that should occur automatically.
Then, when playing each of the four instruments, a signal is seen in each corresponding mixer channel meter. Note that each meter shows two bars as though the input signal might be stereo - but of course the input signal to the mixer is not stereo.
Note that this behavior may not occur when using a “standalone” plugin (not Kontakt-hosted). I have verified this with Arturia plugins - stereo signals are passed from the Arturia plugin through the Dorico mixer.
I’d like to hear if others can verify and possibly explain the behavior I’ve described. Possibly someone can even explain how I am mistaken! ![]()
