Owner's Manual
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™.

Introduction

What is the G2M™?
The G2M™ is a simple to use and highly
effective converter. It's the fastest,

MIDI

most accurate, way to turn any musical
instrument into a instrument.
MIDI
Your new "Version 3" G2M™ features
several enhancements compared to the
previous versions, including support for
bass-register instruments and the latest,
state-of-the-art pitch-detection algorithms
only available from sonuus.
Designed to give accurate triggering, with
ultra-low latency, it is a true plug-and-play
solution for converting monophonic audio
into . It can be used to sequence bass
MIDI
lines and guitar solos, add an edge to your
live performances and to open up many
creative possibilities.

Power

9V DC

Your G2M™ can be conveniently powered
by a 9V DC power supply. Its low current
requirement (<30mA) means almost any
standard 9V power supply can be used
(2 1mm centre-pin, positive tip).
·
Battery (AA)
For true portability, the G2M™ can also be
powered by a single AA battery (alkaline or
rechargeable). Simply open the battery
door and put in a 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 the battery is
inserted correctly.
Because of its low power consumption, the
unit will run for many hours (typically for
more than 20) on a single battery. When

It is always best to start at a lower pitch and
tune upwards to the correct pitch. As you
