Threshold setting how much of the modulation will be used. You will see
that the white markings around the Threshold knob turn red based on the
input signal (kind of like a VU meter), which makes it really easy to see
changes in the level of the input signal and set the Threshold accordingly.
Rate Mod
The Rate Mod knob allows you to dynamically increase (or decrease) the
rate of the LFO or Rhythm based on the level of the input signal, and the
Threshold setting as discussed above. The modulation is either added or
subtracted from the basic Rate as set on the front panel. The setting of this
knob determines the maximum amount of rate modulation that can occur
The Rate Mod knob is bi-polar; when set straight up it is at the ‘zero’
position. As you turn the knob clockwise the rate will increase based the
setting of the knob and/or the numbers entered into the LED display below.
As you turn the knob counter-clockwise the rate will decrease based on the
knob setting and/or the numbers in the LED display below the knob.
The Rate Mod scale is in octaves and is based on standard frequency scale;
a setting of ‘1.00’ will provide a doubling of the speed (x2), a setting of
‘2.00’ will double the rate again (x4) and so forth. So a setting of ‘3.00’ is
equal to a three-octave increase in the rate (x9). The same approach is
used as you turn the knob counter clockwise, except that the rate is
decreased (slowed down) as opposed to sped up.
It is also important to note that you can still modulate the Rate even if
PanMan is synced to an incoming midi clock. What happens is the rate is
driven out of sync and sped up or down but once the mod level drops back
to it’s ‘normal’ or base level PanMan will grab hold again and dance in sync
with the incoming midi clock. Cool, no?
