Congratulations on your purchase of the
G2M™. Please take the time to read
through this manual to ensure you get
the best from your G2M™.
What is the
G2M™
?
The G2M™ is a simple to use, but highly
effective, Guitar-to-
MIDI
converter. It is
“Universal” because it doesn’t need a
special pick-up mounted on your guitar,
but instead simply connects to your
guitar like any other effects pedal or
tuner. However, this does mean that it
can only work “monophonically”, so
chords are not supported.
Designed to give accurate triggering,
with low-latency, it is a true plug-and-play
solution for monophonic
MIDI
guitar. It
can be used to sequence bass lines and
guitar solos, add an edge to your live
performances and to open up many
creative possibilities.
Power
Your G2M™ is powered by a single 9V
PP3 battery (supplied). Simply connect
the battery observing the correct
polarity. If you connect it the wrong way
round it won’t cause any damage, but
the unit won’t operate until this is
connected correctly.
Because of its low power consumption,
the unit will run for many hours (typically
for more than 70) on a single battery.
When the battery is close to needing
replaced, the
LOW
BATTERY
LED
will light. It
is not necessary to replace the battery
immediately since the G2M™ will
continue to function normally. When the
battery is exhausted, the G2M™ will stop
functioning and the battery must be
replaced. If you need the G2M™ to work
reliably (
e.g., a recording session, or
when playing live) the battery should be
replaced if the
LOW
BATTERY
LED
is lit.
The G2M™ is switched on when a lead is
plugged into the
GUITAR
jack. So, to
maximise battery life, this jack must be
disconnected when you are not using
the unit.
Operation
Using your G2M™ couldn’t be simpler:
• Plug your instrument (electric guitar)
into the
GUITAR
jack socket. The
POWER
LED
will light.
• Connect your
MIDI
device (or
computer,
etc.) to the
MIDI
OUT
socket.
• Adjust your guitar’s volume control
so that the
CLIP
LED
lights only
occasionally while playing normally.
• Optionally, check your guitar is in
tune using the built-in tuner (if you
want to tune to the standard
EADGBE
tuning).
• Play your guitar to send
MIDI
to your
MIDI
device (or sequencer,
etc.).
Boost
If your guitar has a low output level, and
you never see the
CLIP
LED
light up in
normal use, enable the
BOOST
switch
next to the
GUITAR
jack socket. This will
boost your guitar’s signal and make your
G2M™ work better with your guitar.
Tuner
For your convenience, the G2M™
includes a built-in tuner. This uses our
PULSAR™ tuning technology where the
POWER
LED
doubles as a tuning indicator.
This innovative tuner gives you a fast
and accurate way to tune your guitar.
If there is no input signal, the
LED
will
remain lit and indicates that the unit is
powered. When there is an input signal,
the
LED
will pulse smoothly to indicate
tuning.
When the note is out of tune, the
LED
will
pulse quickly. As you get closer to the
correct pitch, this pulsing will slow.
Eventually when you are perfectly in
tune, the pulsing will stop. Normally, as
long as the
LED
pulses slower than once
per second, the tuning is close enough
for most purposes.
It is always best to start at a lower pitch
and tune upwards to the correct pitch. As
you get closer to the correct pitch and
the pulsing slows down, turn your tuning
head more slowly to avoid overshooting
the correct pitch. Because the tuner is
very accurate you will find that very small
movements may be all that is required to
move from slightly out-of-tune to in-tune
(or indeed, to go from in-tune to slightly
out-of-tune). With only a little practice
you will find you can tune very quickly
and accurately using the PULSAR™
tuner.
Instrument Thru
If you want to connect your instrument to
another device, or to your guitar
amplifier, simply connect a lead to the
THRU
jack. The G2M™ has a high-
impedance input and it will not affect the
sound of your instrument while it is
connected.
MIDI
To make connecting to
MIDI
equipment
as simple as possible, the G2M™ has a
standard 5-pin
MIDI
connector (
i.e., no
adapter cables are required). It also
provides standard 5V power and is able
to power self-powered
MIDI
devices such
as
MIDI
mergers and message filters.
For pitch-bend, the commonest setting
for most
MIDI
devices is for full-scale
pitch-bend to represent ±2 semitones,
and the G2M™ is also set to this range.
To ensure your
MIDI
sounds are correctly
in tune with your guitar, ensure the
MIDI
patch you use is also set to a pitch-bend
range of ±2 semitones.
Of course, you may want to experiment
with other pitch-bend ranges for special
effects.
Carry strap
Next to the
GUITAR
jack socket is a hole to
attach a carrying strap. You can use this
to make carrying the G2M™ much
easier: wear it on your wrist to free up
your hands; wear it round your neck so
it’s always nearby.
