1. Description.
The amp interface allows switching channels and other amp functions via midi messages. In case
of MESA BOOGIE amps, Peavey JSX ( and similar ) no external power is needed.
The interface may replace original footswitch and it is possible to switch all available footswitch
functions by one midi message.
sockets: Midi IN – Midi socket
AMP FS – connect it into the footswitch socket of the amp
indicator: RX – Received midi message indicator
switch: Midi CH. SW. – Midi channel settings switch ( learn mode )
2. Using the interface.
2.1. Starting up the interface
●Power off the amp
●Connect the interface into the amp using original footswitch cable
●Connect the interface to the midi controller using standard midi cable
●Set a valid midi channel (chapter 2.3)
●Power on your system
After powering on the interface, RX LED is blinking for a one second and then goes off.

2.2. Working with midi messages.
The midi interface supports 2 types of MIDI messages:
- Program Change ( PC )
- Control Change ( CC )
According to the MIDI standard, all midi parameters range from 0 to 127
Program Change messages are used to recall presets and Control Change messages are used
to switch one function independently from presets.
●Send a valid midi message to switch your amp.
Refer to the table of default settings of supported amplifiers (AMI midi implementation).
User should send supported PC or CC including valid MIDI channel.
MIDI channel sent from the midi controller to the interface must correspond to MIDI channel
set in the interface.
Note: Some manufacturers use the range of 1 – 128. In this case, all of listed below values should
be increased by 1.
Example: The controller sends midi messages in the range of 1 – 128.
If you want to switch the interface by PC 0 you should send PC 1 from the midi controller.
2.3. MIDI channel settings.
Default MIDI channel is 1, but it is possible to change it.
- Press and hold switch until the LED starts blinking.
- The interface is in channel learn mode.
- Send any midi message ( PC or CC ) with new midi channel set.
- The interface will remember the midi channel.
Note: Midi channel number 16 is OMNI channel
