Decay
Sets the basic decay time of the noise envelope. Smaller values produce a shorter burst.
VelTrk
Controls the degree to which key velocity affects the key click volume. A value of zero means
that the key velocity has no effect on the key click volume (which is like a real tone wheel
organ). Other values add volume as the velocity increases.
Pitch
Sets the basic pitch of the key click noise, relative to the highest tonewheel's pitch. The pitch
is controlled by a steep lowpass filter applied to white noise. The filter's cut off frequency
is controlled relative to key number, higher keys move the cutoff frequency up, lower keys
move the cutoff frequency down.
Random
Controls the degree to which a random amount of amplitude variation is added to the key
click.
ReTrigThresh
This parameter lets you set the volume level below which key click must decay before it will
be retriggered.
Note Attack
Controls the attack characteristic of notes. Normal provides a smoothed attack, while a
setting of Hard has an instant attack and will produce an audible click, in addition to any
amount of key click specified with the other parameters on this page (you might prefer not to
specify any additional key click when you use this setting). PercHard sets a hard attack level
for percussion only; notes without percussion use a normal attack.
Note Release
Controls the release characteristic of notes. A setting of Normal has a smoothed release,
while a setting of Hard has an instant release. Hard will produce an audible click.
