    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. © Oz inventions Version 1.13...

    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. If in doubt contact Oz inventions at contact@ozinventions.com © Oz inventions...

  • Page 8: Warranty

    The device is warranted for use in Australia. If the product is defective as a result of faulty workmanship or materials, Oz Inventions will at their discretion repair or replace the product for a period of 12 months from purchase.

    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.

    Connect the connect the 5-pin DIN socket to the MIDI device to be controlled using a male to male 5-pin DIN cable. Figure 3 – Connecting the MIDI jack The input TRS plug/socket connection is firm and should click as it is made. The plug should be pushed gently until it will go no further. © Oz inventions Version 1.13...

    Multiple enhancers can be used in series to control multiple devices with a single expression pedal. Using each enhancers calibration function allows different parts of the pedals sweep to affect the units differently.

    If it is in the wrong position, the result can be no output. Whenever the menu is exited, be sure to correctly place the minimum depth control. If at any time modulation is not working as expected, check the minimum depth control, and also the maximum depth control and the sensitivity control. © Oz inventions Version 1.13...

    Both switches must be held together, with the on/off/calibration/recording switch being held first. The MIDI menu is exited by pressing the on/off/calibrate switch whilst pulling the modulation mode switch. © Oz inventions Version 1.13...
  • Page 19 After menu exit, It is important to return the depth controls to their required positions System reset System reset is actuated by holding the modulation mode switch forward, whilst applying power, and then releasing the switch. The system is then returned to default settings. See pg 40 © Oz inventions Version 1.13...

    Time’ set in the menu. The recording can be heard by selecting playblack (‘P’) with the modulation mode switch. The recording will play back continuously and can be trimmed using the trim (sensitivity) control. The recorded waveform cannot be saved.

    Fully anti-clockwise (0) is no trim. Fully clock-wise trims the entire recording, leaving nothing left to play and so no output change. Initially in playback mode start with the trim control fully anti-clockwise so you can hear the entire recording, and then work toward clockwise to remove the trailing section/s. © Oz inventions Version 1.13...
