recognize them. The Switch Doctor can send up to three Program Changes on three

different MIDI channels. (see SETUP MODE – Setup Functions on page 17)

MIDI Continuous Controller Switches

MIDI Continuous Controller messages are often used as ON/OFF type switches for

toggling functions, loops, or effect blocks within a MIDI device. For example, a multi-

effect device can toggle just the delay, on or off. The Controller ON/OFF switches can

also be used for controlling an effects bypass.

Another use for MIDI CC messages is for setting specific values of effect parameters

such as modulation, tempo, feedback, etc.

The Switch Doctor can send up to eight Continuous Control Change messages on two

different MIDI channels. Each switch can be independently assigned a MIDI CC# and

"ON" Value from 001 to 127 (see SETUP MODE – Setup Functions on page 17).

MIDI Note ON

MIDI Note-On messages can be used to trigger samplers. The Switch Doctor can send

up to four Note-On messages on a single MIDI channel. Each MIDI Note-On message is

quickly followed by a Note-Off message, as if a key was quickly pressed and released.

This helps to prevent stuck notes. Most samplers can be set to trigger only with Note-

On messages, ignoring the Note-Off (see SETUP MODE – NT.A on page 18).

MIDI Expression Pedal

Using an expression pedal with the Switch Doctor allows MIDI Continuous Controller

data to be sent when the pedal is moved.

The Continuous Controller Number and the MIDI Channel for the expression pedal can

be assigned per preset. This allows the pedal to be assigned to different MIDI devices

for different presets (see PROGRAMMING PRESETS – PDL on page 23).

There is also a global MIDI channel for the expression pedal which can be used to set

the channel for all presets. This is useful for using the pedal to control a single MIDI

device (single MIDI Channel). See SETUP MODE – PDL on page 19 for details on

setting up the pedal.

By default, when a preset is recalled on the Switch Doctor, the current expression

pedal position is not transmitted. The pedal position data is transmitted once the pedal

is moved. However, it is possible to transmit the current pedal position when a preset

is recalled by enabling the option in Setup Mode. See SETUP MODE – PDL on page 19

for details on setting up the pedal.
