In SuperDirt, reverb and delay are shared across all voices on the same orbit
In SuperDirt the orbit parameter selects which effects bus a voice uses, and reverb/delay are shared across every voice on the same orbit. Two voices on orbit 0 therefore feed one common reverb/delay tail; to give a voice an independent tail you route it to a different orbit. Expecting per-voice reverb without splitting orbits produces a single blended wash instead. Splitting orbits is the standard way to keep, say, a vocal delay separate from a drum reverb.
Examples
d1 $ s “bd” # orbit 0 // shares FX bus 0 d2 $ s “hh” # orbit 1 // independent reverb/delay tail on bus 1
Assessment
Two SuperDirt voices on the same orbit share what, and how do you give one of them an independent reverb tail?
