  • Page 12: Audio And Switching Features

    There are three audio buffers in the Mastermind PBC: one in front of loop 1, one before loop 7, and one after loop 10.
  • Page 13: Internal Line Mixer

    The Mastermind PBC allows you to choose which loops are in series and which are in parallel for each preset. This is done by entering loop selection mode (press the Loops button), then holding the desired loop (7 through 10). This will switch the loop from series to parallel (or from parallel to series).

    Function Switching a.k.a. Controlling Your Amp The Mastermind PBC has the ability to control footswitchable features on many amps. This could be channel switching, reverb, tremolo, etc. – anything that is controlled by a 1⁄4-inch footswitch jack. The Func Sw 1/2 and Func Sw 3/4 jacks are be used for function switching purposes.
  • Page 15 TRS 1⁄4-inch cable – this allows you to control two functions on an amp with each switching jack, providing access to all four function switches. This connection is typically used with amps that have two button footswitches. Insert cable – an insert cable is a 1⁄4-inch cable that has a TRS (aka stereo) connector on one side and two 1/4-inch mono connectors on the other end.

    Adding a Device The first thing that needs to be done is to add a device entry to the Mastermind PBC for each device you wish to control. Once in the setup menu, select the Edit Devices option by using the down arrow button to highlight the option, and the Select button to select the item.
  • Page 25: Assigning Program Changes

    If your device is listed, the Mastermind PBC can set up many of the device parameters for you. What it can do varies from device to device. At the minimum, it can set up the device name and the number of presets and banks the device has.
  • Page 26 To do this, enter setup mode by holding the 1 and 3 buttons for 3 seconds. After entering Setup Mode, select the Edit Presets option: Setup Menu Current Pg Set List None Edit Devices Edit Presets Audio Settings Fn Switch Settings You’ll be presented with a list of presets: Select a Preset Global Preset...
  • Page 27: Song And Setlist Mode

    Please note! Even though you can specify up to 16 presets per song, you can only access as many presets as you have preset buttons on your Mastermind PBC. By default that means you can use 5 presets per song. If you use the Mastermind PBC editor, you can convert more of the buttons to preset buttons if needed, and you can use two Mastermind PBCs together in Expander mode, which would allow you to use preset buttons on both units.
  • Page 28 In the menu that pops up, you can either choose your desired set list, choose “All Songs” which puts all 1008 songs in one large setlist, or choose “None” to select no setlist and return to normal preset and bank mode.
  • Page 29: Expression Pedals

    You can also use a standard volume pedal as an expression pedal. For this you need a 1/4” Y-cable, also known as an insert cable. The stereo end of the Y cable plugs into the Mastermind PBC and the two mono ends plug into the input...
  • Page 30: Setting Up The Expression Pedal Position Switch

    Currently, this function is only programmable using the Mastermind PBC editor software. You will, however, need to use the Mastermind PBC to choose at what point in the pedal’s travel the switch happens. Move the pedal to that spot (typically not quite all the way down or not quite all the way up), then press Set Switch Position. The pedal position will be remembered and the selected function will switch on and off as you move the pedal up and down.
  • Page 31: External Switches

    There is an external switch jack on the rear of the Mastermind PBC labeled “Ext Switch”. This jack can take a single switch or a double switch with a TRS (tip-ring-sleeve) plug. A single switch should use a TRS plug with the switch connected to the tip and ground, and the ring conductor unconnected to anything.
  • Page 32: Remote Mode And Expander Mode

    In Remote Mode, one Mastermind PBC can act as a remote control for another. Simply connect the Remote In port of your Mastermind PBC to the MIDI Out of the unit that should act as a remote control. If needed, you can even chain more PBCs in this way, connecting the Remote In of one unit to the MIDI Out of the next.
  • Page 33 When using Expander mode, your presets will be spread across the preset buttons on both units, starting on PBC #1 in the diagram above, and then continuing to PBC #2. You can put the bank and page selection buttons on either unit or both.
  • Page 34: External Midi Control

    External MIDI Control The Mastermind PBC can also be controlled by an external MIDI device such as a computer, sequencer or other type of MIDI controller. To enable this feature, set the MIDI Rx Ch parameter in the MIDI Settings menu to the desired MIDI channel.

    Using the setup menu, you can also set it to be a tap tempo button that sends MIDI clock (see below). A third option is to have the Function button control a Mini Effect Gizmo that’s connected to the Mastermind PBC. This allows you to add five more loops to your pedalboard.

    “None” (the default), “Master” or “Slave”. When set to “Master”, the Mastermind PBC will send a MIDI clock signal out of all MIDI outputs, including the USB port. The tempo will be adjusted any time a tap tempo button is used. Tempo can also be set on a per-song and per-preset basis.

  • Page 39: Connecting To A Computer

    In addition to the USB flash drive support, the Mastermind PBC’s USB -> PC port allows you to connect your controller to a PC or Mac with a USB port. The Mastermind PBC is a class-compliant USB MIDI device, which means it doesn’t need additional driver software.
