All About MIDI
Common Connection &
Configuration Problems
OK. Before we go any further lets now look at some of the
reasons why your MIDI devices wont talk to each other. If
you have problems with MIDI communications while trying
a bulk dump/load, any of the applications or patch editing
described below then revisit this section. As they say,
forewarned is forearmed. A LOT of users have problems
when connecting up MIDI so I'll try and go through as
MUCH as I can think of.

Make sure the GT-3/5's MIDI OUT is connected
to the target device's MIDI IN
3.
Make sure you have a proper MIDI cable (wired
straight thru not crossed like some audio 5-pin
DIN cables)
4.
Check the MIDI TX Channel. Also if using TX
Channel set to 'RX' make sure the MIDI RX
Channel is correct
5.
If transmitting SYSEX data (i.e. Bulk Dump) make
sure the Device ID is correct
6.
Check the receiving channel on the receiving unit
is set to the same as the GT-3/5 TX Channel.

expression pedal like the Digitech MC-2.

configured correctly

make sure MIDI or MMC start/stop is not selected

1. GT-3/5 is mid-chain, but MIDI messages do not
get to a unit linked to the output of the GT-3/5
even though the GT-3/5 is receiving OK.

2. MIDI Thru is not supported by the GT-3/5

3. Use a MIDI splitter such as those produced by
Philip Rees in the UK. If you then require the
output from the GT-3/5 merge the signal from the
GT-3/5 back into the chain using a MIDI Merge
unit also available from Philip Rees.
