Introduction Congratulations on purchasing the Mini Effect Gizmo audio loop switcher! The Mini Effect Gizmo has been designed to provide our acclaimed audio loop switching technology in a small package suitable for pedalboards, rack drawers and other places where a full sized switcher won’t fit. The Mini Effect Gizmo provides five true bypass audio loops and a professional quality audio buffer in a compact design.
Front Panel Buttons 1 through 5 - These buttons turn audio loops 1 through 5 on and off. Each button lights up to indicate that the corresponding audio loop is active. Write – When held down for 3 seconds, this button saves the current switch state to non-volatile memory. Buttons 1 through 5 will flash to confirm that the state has been saved. This function is not active until a Program Change message is received at the MIDI In jack. See the MIDI Usage section for more details.

Rear Panel Buf In – This is the Mini Effect Gizmo’s buffered input. Plugging into this jack sends your guitar signal through the buffer and then on to the audio loops. See the Special Features section for more information on the audio buffer. In – This is the passive input to the Mini Effect Gizmo. Plugging into this jack sends the guitar signal straight to the audio loops, with no active circuitry in between. Plugging in to the In jack overrides anything plugged into the Buf In jack.
MIDI In – Jack for incoming MIDI commands. Connect your MIDI foot controller here using a 5-pin or 7-pin MIDI cable. The Mini Effect Gizmo will phantom power a compatible MIDI controller if you use a 7-pin MIDI cable. The AC adapter provided with the Mini Effect Gizmo can phantom power most MIDI controllers, provided the controller accepts 9VDC at no more than 300mA. Power – This unit requires power supply of 9 volts DC. The plug should be a 5.5mm/2.

MIDI Usage The Mini Effect Gizmo can receive MIDI messages from any MIDI controller. You can store different switch settings for MIDI program numbers 1 through 128 in MIDI banks 0 and 1. When a Program Change message is received on the correct channel, the Mini Effect Gizmo will automatically recall the saved settings for the given program number. To set up for MIDI use, simply connect your MIDI controller to your Mini Effect Gizmo’s MIDI In jack. The Mini Effect Gizmo is set for MIDI Channel 1 by default.
Continuous Controllers In addition to supporting MIDI Program Change messages, the Mini Effect Gizmo supports MIDI Continuous Controller messages.
Backing Up Your Settings: SysEx Dump A SysEx (System Exclusive) data dump will send the current Mini Effect Gizmo system configuration out through the MIDI Thru/Out port. You can then save this data to your computer, or copy the settings directly to another Mini Effect Gizmo. Hold down the Switch 5 button while powering up the Mini Effect Gizmo, and the Mini Effect Gizmo will immediately send the SysEx Dump. It only takes a couple of seconds to complete.
Special Features Audio Buffer Using long cables or many effects may degrade the guitar signal, causing it to lose clarity and definition. The audio buffer is used to “strengthen” the guitar signal and preserve sound quality. The effect may vary from subtle to significant, depending on the length and quality of cables and type of effects used in your rig. Plugging into the Buf In jack will put the buffer in the audio path, and plugging into the In jack will bypass the buffer.
Setup Mode Selecting MIDI Channel and MIDI Options Hold the Switch 1 button while powering the Mini Effect Gizmo on. Keep holding the button until the LEDs flash. The Switch buttons will now allow you to select the MIDI channel the Mini Effect Gizmo responds to, as well as other MIDI-related options: MIDI Channels The Mini Effect Gizmo is set by default to send and receive on MIDI Channel 1.
Continuous Controller Ranges The Switch 5 button controls the Continuous Controller range for all switches: CC Range 80…84 88…92 (default) GCX Number 1 2 Switch 5 LED OFF ON GCX Compatibility Mode To make the Mini Effect Gizmo work like a GCX by Voodoo Lab, turn on all of Switches 1-4 in setup mode. This sets the MIDI channel to 16, which is the channel used by the GCX. The GCX number (GCX#1 or GCX#2) is set by Switch 5 (see above).

This can be placed in front of an amp, or in an effects loop.
Troubleshooting Problem: The LEDs don’t flash when you hold down the Write Button. Solution: The Mini Effect Gizmo did not receive a MIDI Program Change message. First, verify that you have a valid MIDI connection. The MIDI output of your MIDI controller should be connected to the MIDI input of the Mini Effect Gizmo by a MIDI cable that’s known to be working correctly. The next most likely cause is that the Mini Effect Gizmo is set to a different MIDI channel than your MIDI controller.
