Sound Set Configration screen

Load on Demand

Enabling this improves memory consumption and loading speed, but may cause noise.
Level 0: Disabled. All samples are loaded at launch.
Level 1: Loads samples when selecting a patch. Not recommended if you switch patches frequently.
Level 2: Loads samples when sounding a voice. Use only if you have a sound set that you just can’t load.

Fix Stereo

If the pan is at its maximum or minimum value in the sound set, the volume level on the opposite side is set to 0.
If the sound set is intended to be split into left and right channels, without this, the left channel sound will be centered when the pan is turned to the right.

Default Velocity to LPF

SoundFont v2.01 and v2.04 differ in the standard definition of the velocity to LPF cutoff frequency modulator.
In v2.01, jumps occur at velocities below 64 and above 64; in v2.04, the transition is smooth.
Some sound sets may have already addressed these behaviors. For those sound sets, the best option is to choose “None”.

Over-Sampling

Increase the sampling frequency to reduce aliasing noise. If this is increased above 1x, the load will increase.

GS Custom Controllers
