The vibrato is scripted, not only with an LFO, but modeled from real flute vibrato, allowing the user to control the vibrato depth and speed in real-time. The flute is sampled in five dynamics and scripting has been added that morphs between these dynamics using crossfades. Passion Flute’s interface allows the user to assign these performance elements to a MIDI continuous controller, or let the script automatically control them.

The flute was sampled in 48,000 kHz, 24-bit. There are over 4,600 samples, totaling 1.15 GB of flute samples. Furthermore, the flute was sampled with five different microphones, from modern condenser mics to a vintage ribbon mic.
