MIDI PROGRAMS AND CONTROL MESSAGES
When the unit is in MIDI mode (LOCAL/MIDI switch set to MIDI) all local programs are disabled and all programs are
instead selected by MIDI Program Change messages with additional functions supplied by MIDI Control Change on/off
type messages. Gain sweeps are controlled by MIDI (sweep) Control Change 0 and by the expression pedal if one is
connected to the expression pedal input. The MIDI CC0 message and the expression pedal perform the same function of
sweeping the selected gain and can both be used in a program without interfering with each other. If one pedal is
moved, then the other, one will simply take over control when it passes by the position of the other.
For MIDI use, the MIDI channel of the unit must be set to the desired MIDI channel as transmitted by your MIDI
controller. The MIDI channel is set by the MIDI channel switches inside the unit.
If you have a movable pedal attached to your MIDI controller, set it to transmit Control Change number 0 over the MIDI
channel set by the switches.
SELECTING
THE MIDI PROGRAM OR CONTROL MESSAGES
The MIDI programs can be divided into several groups as described here. Each group has a chart which can be referred
to for specific program and control numbers.
Fixed gain programs:
These programs force the Volcano to a fixed gain anywhere from mute up to the maximum gain of
the unit (6dB for LINE or +18dB for INSTRUMENT) in 2dB increments. When these programs are selected the MIDI CC
and expression pedal have no effect. Use these programs to jump directly to a specific amount of gain and to ignore the
current pedal position.
REFER TO THE FIXED GAIN PROGRAMS CHART FOR SPECIFIC PROGRAM NUMBERS
Sweep gain programs: Use these programs to allow the Volcano to respond to the MIDI CC pedal movement or
expression pedal movement. Choose a program in this group to select a specific range for the pedal such as a full range
from off to 18dB or a more limited range such as -30dB to 0dB. In addition there are several pan programs in this group.
The pan programs are only used if you are using 2 or more Volcanoes together to pan a signal between 2 or more amps.
See the Tech Tips section for tips on how to create pan setups.
REFER TO THE SWEEP GAIN PROGRAMS CHART FOR
SPECIFIC PROGRAM NUMBERS
Special function programs: Use these programs to perform special operations on already selected programs or for
additional functions: REFER TO THE SPECIAL FUNCTION PROGRAMS CHART FOR SPECIFIC PROGRAM NUMBERS.
Control Change on/off messages (Instant Access): In addition to selecting programs with Program Messages, programs
can be altered using on/off type Control Change messages (sometimes referred to as Instant Access messages). These
types of messages are appropriate when some parameter in a program needs to be modified without changing presets.
Some of these functions include mute on/off, bypass on/off, boost on/off, and so on. The controlling controller will
typically indicate if the state is on or off.
