GM Arts Firmware for BJ Devices TB-12
  User Guide

Overrides are only available when you select Advanced Options in the editor.

Overrides give you the ability to change default settings to do something different, such as:

• For patches A2 and B3, change the usual settings for effect 1 to a phaser and set pedal 2 to control whammy pitch
• For all patches in bank C, set relays 1 and 2 both on, and send a system exclusive message
• For patch D5, change all effect footswitches to something else, and send them on a different MIDI channel
• For patch G2, swap the positions of the overdrive and boost effect footswitches

These are very flexible and powerful options, so here's an example of how to make a simple change for patch A2, to use a phaser effect on effect 3, instead of whatever it normally does.

The first thing to notice is that on the MIDI, Effects, Pedals and Patch Change tabs, the sliders give you the normal default settings at the left and override settings as you scroll further to the right. When you make override settings, they are available to be used, but will not be used until you select them on the Overrides tab.

1. So our first step will be to choose the Effects tab, scroll to Override #1 and make CC settings to turn your phaser effect off and on.
2. Then go to the Overrides tab and press [Add Override].
3. Select the patch(es) you want to modify, patch A2 in this example and check Fx3 Override, setting it value to 1, because we're using effect override number 1.
4. Click [OK] and that's it - you'll now see you have set up this override and effect 3 will control a phaser in patch A2 only.

BUT WAIT …

Just before you get too excited and set up lots of overrides, take some time to decide whether you want to select MFC patch numbers or MIDI program numbers. This selection affects all existing overrides, and changing it can affect some of your settings.

• Using MFC patches is the easiest to manage and has some handy multi-select options such as "All patches in bank C". This is the recommended option.
• Using MIDI program numbers might make sense if you only have one connected device and want certain MIDI programs on that device to have overrides, regardless of which MFC patch selects that MIDI program.

Now you can go ahead and set up the overrides you need. The process is always the same:

1. Set up the overrides you need first. You can set up overrides on the MIDI, Effects, Pedals and Patch Change tabs.
2. Go to the Overrides tab and add or edit your overrides.

You can use the [Move] buttons to change the order of overrides, and this is mostly for your own convenience. But note that if the same patch is in more than one override, only the last one will be used. For example if Override #1 is "for all patches in Bank B, use MIDI channel 2" and Override #5 is "for patch B2, set relay 1 off", then only the last override will be used for patch B2.
