Reverb & delay sends
Two global FX buses (reverb + delay) are wired in parallel with the dry path. Each track has its own send level into each bus.
Per-track sends
Open the FX tab to see the send sliders. They tap each track's post-insert signal, so what you send is what the track sounds like.
Bus controls
The FX tab also exposes the bus parameters: reverb size + dampening, delay time + feedback. Both buses feed into the master compressor on the way to the speakers.
