OVERLOAD INDICATION
The Volcano has a signal level detection circuit that warns the user if either the input signal level or the output
signal level exceed the headroom of the unit. Both the instrument/line level switch setting and the currently
selected gain are taken into account when measuring the level. The STAT led will momentarily blink yellow if
the signal level gets within 3dB of the maximum input or output signal level, and will blink red if the maximum
signal level has been reached. Overdriving the unit will not damage it, but exceeding the maximum signal level
will result in distortion in the signal.
USING MIDI BASED EXPRESSION
IMPORTANT: If you plan on controlling the Volcano's sweep using MIDI CC from your MIDI foot controller, be
sure that the footcontroller is set to output data as a LINEAR instead of LOG function when the pedal is
moved. Setting the controller to linear simply means that when the pedal is in the mid position the data value
that is output is half way between 0 and 127. If set to log, the MIDI data will bunch up on one side of the
sweep range resulting in an uneven change in gain in the Volcano.
