Declaration of compliance
Manufacturers Name: Oz Inventions
Manufacturer’s address: PO Box 86, Warrnambool, Victoria. 3280
Declares that the product
Product name: Xpression fX Expression pedal enhancer (MIDI)
is compliant with the following standards regarding radiated and conductive emissions relevant to
this product and Electro Magnetic compatibility.
AS/NZS 4268
AS/NZS CISPR 32
Should the equipment cause radio frequency interference (disturber) or be the victim of radio
frequency interference, the following measures can be taken:
Relocate the disturber and/or the victim by increasing separation and/or reorientating the
device/s.
Connect the disturber and victim on different power circuits
Contact the manufacturer or other expert party

Please read these two very important messages
1. The position of the sensitivity, minimum depth and maximum depth controls are important in
obtaining the correct amount of modulation. Having these controls in the incorrect position may
mean no modulation, little modulation or erratic modulation.
The sensitivity control is used to set the number of steps from the heel to toe position. Fully left gives
128 steps from 0 –127. Fully right gives the custom step sizes set in the ‘step size’ menu. Other positions
increase the step size. It needs to be positioned correctly, for the desired effect.
The minimum and maximum depth controls have multiple functions, operating on modulation and also
changing items and parameters within the menus, and so these controls are often moved and need to be
re-positioned for the desired effect whenever the menus are exited or the modulation mode is changed.
Failsafe starting positions outside of the menus are
Sensitivity –Fully left (0)
Minimum depth –fully left (0)
Maximum depth –fully right (127)
If at any time things are not working as expected, check those controls.
2. It is easy to assign unwanted values to the full range of continuous controllers (0 –119)
accidentally. So, when changing continuous controller numbers ensure that either the modulation
on/off switch is off, or that the continuous controller is disabled.
If the unwanted condition does occur, it may be simplest to reset the receiving MIDI device rather
than individually resetting each continuous controller.

Provided items
Expression pedal enhancer - MIDI
DC 12 volt 150mA power supply (optional)
TRS to 5 pin DIN adapter (dependent on model and optional)
3 meter 5-pin DIN male to male (optional)
Quick start manual (optional)
Safety and care
Remove power from all devices to be connected before connecting or disconnecting
Dismantling the device may damage the device. There are no user serviceable parts inside the
device.
Only use the provided AC to DC power adapter or other certified adapter. Only use the correct
polarity of the provided reversible DC power adapter. Negative centre (tip) is the correct polarity.
The power adapter is supplied in the correct configuration. Do not reverse the connection.
Electromagnetic radiation is minimised by the aluminium enclosure and relevant internal
components. However, should interference be experienced, position the device further away from
the device that is interfering or being interfered with.
Due to the nature of modulation, some modulated parameters, particularly at the ends of
modulation, can cause a loud and/or irritating audio signal. Permanent high volume audio signals
can damage hearing and equipment.
Should the device malfunction, a reboot or restore to default settings, may resolve the problem.
Otherwise the manufacturer should be contacted. There are no user serviceable parts inside the
device.
Avoid contact with, and environments, known to cause adverse effects with electronics and small
moving parts, such as liquids, dust, sand, high humidity, high temperature and vibrations.
Avoid excessive force when operating controls and connecting cables
Disconnect the device during lightning storms and /or times of power outages
This modulating device is designed to only be connected to a MIDI receive port. Do not connect
the output socket to any other device else either device may be damaged.

Introduction
Expression pedal enhancer - MIDI, from Oz Inventions, is a MIDI controller. It is designed for use with MIDI
devices such as keyboards and effect units with a 5-pin DIN MIDI receive socket.
The device accepts a TRS expression pedal as an input and provides unique expression capability and a MIDI
transmit output signal.
The device can function as a -
Expression pedal enhancer / MIDI controller
Triggered ADSR envelope shaper
Triggered foot switch
Recordable ADSR envelope shaper
Standalone manual ADSR envelope shaper
Foot switch / sustain switch
Automatic or triggered arpeggiator (using pitch parameter on MIDI receive device)
The device is compatible with MIDI devices that have a MIDI 5-pin DIN receive port and it has the following
features.
Controlled expression via expression pedal input and automatic and recordable waveforms
Scalable output in step sizes from 1 –127
Linear, logarithmic and anti-logarithmic sweep
Reverse, forward & continuous sweep
Adjustable minimum and maximum depth modulation positions
Adjustable start and stop sweep positions
Sensitivity control
50 millisecond to 99 second per stage, ADSR envelope shaper
triggered ADSR envelope shaper
Automatic triggered ADSR envelope shaper
15 minute motion sensing recording ADSR envelope shaper
