Guzheng

Articulations

Vibrato / Note bend

Vibrato can be performed either manually with the pitch wheel, or the built in vibrato with the "vibrato knob".
Only hold notes are affected by the note bend/vibrato, letting the rest of the strings ring out

If you want to bend all notes, there is a knob for that as well called "bend all"

Strum

Adds strumming noise. Clean pick -> Strum

Pick position

The sound is very much affected by where you pick the strings. This is adjustable from close to the bridge to the middle of the string.

Dampen/ mute strings

Not really a thing you do with the guzheng, but I mean why not.

Dynamics

Full dynamic range for each string.
The dynamics can be controlled by either the note velocity or the mod wheel. This is adjustable with the knob "Vel dynamics"
