Midi-in
Midi-in is easy to use; Midi in signals will just press a footswitch for you, so that when you have
set up each patch on the G2 you can access them using Midi, just the same as if you had
pressed the foot switch yourself. Of course you can press the foot switches yourself at the same
time as well, nothing is locked or suspended.
G2 uses Program change commands on CH1. Bypass is activated by sending the G2 a
program change 0. All the other foot switches can be activated by the corresponding foot switch
number. For example Program change CH1 04 will effectively push foot switch 4. (This is C0 04
in hex or 11000000 00000100 in binary).
Program change CH1 16 is a very special program change code for your G2. When this midi
code is seen your G2 will toggle the engage button; this gives you access to another complete
level of stored patches.
For ease of use program changes CH1, 17, 18, 19 to 30 will activate the foot switches in the
same way as CH1 1 to 14 so that you can directly address patches in standard level and in
engage level, with just one Midi program command.
Other interesting MIDI features.
We have set Midi in CH2 as a do not respond channel. You will see that your G2 has received
the midi word; however, your G2 is programmed to ignore all Midi input commands on this
channel.
Filtered MIDI Through
The Midi-in signal will be passed to the Midi out of your G2; however, only program changes will
be passed through to the Midi output all other Midi messages will be filtered. This filtered Midi
through can be switched off, for example when connecting two G2 devices together. Please see
special functions to switch off Midi through.
Reset using MIDI
Any program change sent to your G2 on Midi CH4 will instigate a soft reset. This is exactly the
same as switching of the power off and then switching it on again. Your G2 will flash then go to
bypass.
