With key shift, the pressed key is shifted. This is not valid for the rhythm part.
Coarse Tune changes the pitch of the note.
Fine Pitch. -100 to -98.4375 cents with values from 0 to 127.
If GS Custom Controller is enabled, the standard is vibrato intensity.
If GS Custom Controller is disabled, the behavior is as defined in the sound set.
V.Rate, V.Depth, V.Delay
Vibrato Speed, Vibrato Depth, and Vibrato Delay. 64 is the center in relative value.
Attack, Decay, Release
Attack rate, Decay rate, and Release Rate of envelope generator. 64 is the center in relative value.
Cutoff Frequency of Low-pass Filter. 64 is the center in relative value.
Resonance of Low-pass Filter. 64 is the center in relative value.

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.
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”.
Increase the sampling frequency to reduce aliasing noise. If this is increased above 1x, the load will increase.
GS Custom Controllers
Enables the controller assignment feature supported by GS. Enabling this will change the behavior of modulation wheels, etc.
Display the parameters of the sound set.
Four modifiers are available as default.
The sound set is left as is, nothing is customized.
Add Soft Pedal
Add a soft pedal function. The soft pedal reduces the volume by 10 dB and lowers the cutoff frequency by 300 cents.
Soft Pedal and Reverb Fix
Add a soft pedal function and set the reverb to its standard setting. It is recommended that you choose this for any sound set you add.
GeneralUser GS mod
This is a modifier for the attached sound set “GeneralUser GS v1.471”. It fixes some mulfunctions that occur in the original sound set.
You can edit the modifier by pressing Edit and selecting it. Editing requires knowledge of Sound Font.

About the MPE function
The MIDI Polyphonic Expression (MPE) function is experimental.
If you enable MPE, you cannot use multiple layers, and all layers will be the same sound.
The “KQ Sampei MPE” audio unit will start up with the MPE enabled.
MPE is turned off when you load a preset that has MPE turned off.
