Each instrument has four outgoing lines that determine how its sound will get mixed to produce the final left and right audio outputs.

LEFT_LEVEL & RIGHT_LEVEL​

The LEFT_LEVEL and RIGHT_LEVEL parameters control how much of the signal goes to the left or right ear. These dynamics can be used to produce stereo panning effects.

REVERB_LEVEL​

The REVERB_LEVEL parameter determines how much of the signal is routed into the reverb component. Musicians refer to this as the "wet" signal, whereas LEFT_LEVEL and RIGHT_LEVEL are the "dry" signal.

APPLY_WIDENER​

Jamdac's stereo widener simulates stereo expansion based on the Haas Effect. When enabled, a delay buffer causes the left ear to receive the instrument's signal later than the right ear. It is delayed by about 3.6 milliseconds (80 samples), an amount typical of large rooms or stadiums. The human ear interprets the separate arrivals as a single sound, but with a more immersive, spacious, or enveloping experience. For such a small time interval, it does not matter much whether the left or right ear has the delay.

The stereo widener is applied to the entire instrument if APPLY_WIDENER is 1; otherwise it is disabled.

Note: In order to hear this effect, it needs to be supported by your audio device and speakers or headphones. Manufacturers sometimes pinch pennies by opting for mono audio instead of stereo, hoping that their customers won't notice the difference.
