STK plucked stiff string instrument.
This class implements a simple plucked string algorithm (Karplus Strong) with enhancements (Jaffe-Smith, Smith, and others), including string stiffness and pluck position controls. The stiffness is modeled with allpass filters.
This is a digital waveguide model, making its use possibly subject to patents held by Stanford University, Yamaha, and others.

void stk::StifKarp::setBaseLoopGain | ( | StkFloat | aGain | ) |
Set the base loop gain.
The actual loop gain is set according to the frequency. Because of high-frequency loop filter roll-off, higher frequency settings have greater loop gains.
