This bit from Bitwig's official introduction covers two of the DAW's more distinctive routing ideas: hybrid tracks and feedback chain inserts. Both reveal how Bitwig treats note data and audio as interchangeable parts of a single signal flow rather than separate domains.
A hybrid track holds both MIDI notes and bounced audio on the same track. Bouncing is non-destructive: the notes stay intact, and both sources feed into the same downstream processing chain. The practical payoff is that you can make audio-specific edits without losing your MIDI data, and any effects at the end of the chain apply equally regardless of which source is playing.
The second idea is inserting devices directly inside a delay or reverb's feedback loop. Bitwig exposes the feedback path as a chain you can populate with any device, including third-party plug-ins. Placing a frequency shifter there, for example, means every repeat is processed before it feeds back, which creates results that are impossible to achieve by placing the same device after the effect.
