Welcome again @roger.schnur ! Kudos for taking on using JackTrip with a new student.
First things first: be friends with free online manuals for the specific items and info you need (allowing for changing of active minds.) Then you can make your own diagrams based on the gear you get.
nuts and bolts:
Is the ethernet cable long enough between the router and the computer?
Are there enough electrical outlets in the space?
In addition to studying the manual and making notes and diagrams, I suggest sitting at the kit with headphones on and place the items that will be needed within arm’s reach and then plug everything in - computer, interface, even a line sight to the router if possible.
A quick look on Page 3 of the Nitro manual shows that the Nitro has USB to the computer, but it only sends MIDI, not audio. As the Nitro’s BFD player only plays MIDI, it also does not send audio to the Nitro’s headphone output - page 22.
JackTrip is audio only – no MIDI. That means the Nitro’s audio outputs will need to be connected to an audio interface’s inputs. Then the audio interface is plugged into the computer via USB. And in the JackTrip settings, the audio interface is selected as the audio input/output source.
In this case, the Nitro’s USB does not get plugged into the computer at all – the Nitro’s audio outputs are sent to the audio interface inputs.
On JackTrip.com Virtual Studio there are just two channels to the studio server: left and right or a mono mix going to both sides.
Regarding the in-line mic attached to the headphones – I am assuming they are also USB and need to be plugged into the computer. In the Mac’s “audio-midi setup” you will need to create an “aggregate device”. The Aggregate Device (you can give it a name) can combine multiple USB devices into one output and can include the audio interface and the mic/headphones.
Honestly, headphones with in-line mics are probably ok for lessons and offer the best communication with an instructor. However, in preparing a student for successfully playing outside of lessons and considering that drummers move around a lot when they play, the in-line mic could pick up unwanted noises. And if the drummer wants to sing and play, in-line mics on headphones have notoriously awful and glitchy audio quality.
The manual will have other good info about gotchas like the fact that the Nitro Max automatically shuts down after 30 minutes of non-operation UNLESS you turn that default feature OFF. Sometimes it takes longer than that during a session to figure things out or other reasons for the system not being active and you don’t want it to go to sleep. The computer hard drive and display also should be set to not go to sleep.
As for audio interface recommendations, I have heard that Sweetwater might be able to suggest the best solution because they know about JackTrip too. I have seen some Nitro drummers on YouTube that use different ones. There are so many to choose from!
Lots to do by jumping on the documentation for specific items, experiment with setting up in the space, and spend time choosing the gear that best suits. We’ll be here waiting for any of your questions and progress reports too!
Best Thoughts.
