GM Arts Firmware for BJ Devices TB-12
  User Guide

You can make some setting changes directly on your TB-12 MFC.

MFC Patches

On the MFC, press [SETUP] and you will see the MIDI program number for you current MFC patch, with effect footswitches showing initial effect states. Effects 1 to 9 are in their usual positions, and tap is blank (its initial state is always off).

Use the [LEFT] and [RIGHT] buttons to change the MIDI program. The 2nd patch has an option for OFF as well as the normal MIDI program numbers. Use the effect footswitches to set their initial states.

Press [UP] and [DOWN] to select the 1st patch and 2nd patch. Pressing [UP] and [DOWN] further will take you to pedal calibration settings (see next section).

When you have settings you want, press [OK], or to exit without saving settings, press [NO].

TIP: If you're managing your patch numbers and effect states on the MFC, you can exclude them from the PC Editor by unchecking "Save Patch Numbers and FX". That way you won't lose settings by not having them synchronised between the MFC and the editor.

Pedal Calibration

This should be done the first time you use the MFC and whenever you change pedals.

On the MFC, press [SETUP] then use [UP] and [DOWN] to get to screens that allow you to calibrate Pedal 1 and Pedal 2.

Make sure the pedal is connected and press [RIGHT] to start. You'll first see the current minimum and maximum pedal values, then the current pedal value. Sweep the pedal a few times from minimum to maximum to set its range. When finished, press [LEFT] to return. Repeat for the other pedal if necessary, then save your settings with [OK], or press [NO] to exit without saving.

Pedal Failures

Pedals are subject to failure or temperamental behaviour due to scratchy pots, mechanical problems and connecting cable faults. The quick fix to disable all pedals is to press [OK] twice - you could even do this in the middle of a solo!

How it works:

Pressing [OK] displays a screen to disable BOTH pedals. You can press [UP] and [DOWN] to scroll through different choices of which pedals to disable: BOTH, NONE, PEDAL 1, or PEDAL 2.

Press [OK] again to disable the selected pedal(s). If configured, this will also send a rest value for the pedal, for example, maximum volume for a faulty volume pedal. If pedals are not disabled, they will be re-enabled. This is a temporary change only - configured settings will be used next time the MFC is restarted.

Press [NO] to exit this screen without making changes.
