Tech Tips.
The variety of Program messages and Control Change messages gives the user a large number of ways to control the
Volcano to match the player's needs. Following are some ways in which the various commands can be used for
particular applications.
Accessing fixed gains on the fly
If you simply want to use the volcano to immediately go to an array of fixed gains, then program your MIDI controller
program switches to select various gains from the fixed gain programs. For example, if you wish to have 2 mute
for your guitar you can set your program switches 1-4 to transmit 00 (for mute), 37 (for 0dB), and 46 (for +18dB of
boost) all immediately accessible when these programs are selected. These programs will disable the expression pedal
and CC #0 so you can dependably go to the expected gain without needing to bother with pedal position or accidental
movement of the pedal.
Using one sweep gain program with increment/decrement to change ranges
Program one switch on your controller to select a typical sweep range in addition to the fixed gain switches as described
above, then have two switches assigned to the increment and a decrement gain programs. This small combination of
switches can give you a wide range of gains. When used with the fixed gains, the inc/dec will move your gain around on
the fly as you see fit while you are playing. If you switch over to the sweep range, the inc/dec switches can be used to
move the endpoint of the sweep (the loudest side) up or down any amount giving you a virtual array of different sweep
settings.
OMNI MODE and CHANNEL 16 MODE
These two Controllers can be used to allow two or more units to respond as a group or to respond individually. For
example if each Volcano is set to its own MIDI channel, then programs on each unit can be set individually by having
switches on your controller set with the channel numbers of the units you want to control individually. If you want a
single switch to then control all units at once (such as an increment/decrement program) then you can use the omni
mode or channel 16 mode to temporarily allow all units to hear the single message incrementing or decrementing all the
gains together. Channel 16 mode differs in that it allows all units to hear on channel 16 in addition to their normal
channel which is useful if you have other MIDI gear connected (on unused channels) that you want to control without
the Volcano units responding, which they would in Omni mode.
PANNING (IN MIDI MODE)
If you have two or more Volcano units, you can send a rising curve pan program to one unit (using its own MIDI channel)
and a falling curve pan program to the other (using its own MIDI channel), and by setting omni mode (or channel 16
mode) to one or both units you can use a single CC pedal over any channel (or channel 16) to pan both units with the
one controller message.
Controlling gain in multiple effect loops
A typical application for the Volcano is to use it inserted into the effect loop of an amp to control the overall volume
without affecting the tone generated by the front end preamp. But you can also insert several Volcanoes into several
amp effect loops and control them all (in local mode or MIDI mode) with a single expression pedal. This is a great way to
free up having to use additional pedals when you have multiple amps and need to use the Volcano in the effect loops.
AND A FINAL NOTE: OUR HEART AND SOUL and uncounted late night hours went into designing the Volcano and the
result is in our opinion the very finest volume effect in the world. We hope you enjoy using it as much as we sincerely
enjoyed having created it for you!
