======Introduction======

The Pedal Box was built to be a very basic extension to a floorboard. Giving it an extra 8 Expression Pedals, and a display to see patch change / CC names, as well as their values.
It has grown far beyond it's original intention. 

**Pedal Box**
 <box 253px right round>
{{mcrozier:durisian_pbx_2.jpg?220x*}}
</box>
Is an expression pedal controller to expand an existing floorboard. \\ 
In addition to adding up to 8 expression pedals, up to 8 relays can be triggered and the LCD display reflects the actions of your existing floorboard as well.

**Pedal Board**
 <box 253px right round>
{{mcrozier:pedal_board_max.jpg?220x*}}\\ 
Expanding into Pedal Board - you can build a complete MIOS Powered Floorboard.</box>
Is a complete MIOS/MBHP powered floorboard. It can support up to 16 buttons, with banks so there is up to 128 virtual buttons. \\ 
//No matter how many buttons you connect, you can always access all 128 virtual buttons// \\ 
It also supports another 16 fixed buttons, that are the same regardless of bank. Great for boost, or effect on/off functions. A further 2 special function buttons allow bank up/down and special functions. \\ 
Up to 8 relay's can be triggered and of course up to 8 expression pedals.

Each button or pedal can be assigned to a specific device, up to 7 devices can be controlled over 7 midi channels.

Pedal Box / Pedal Board features an extensive display system; \\ 
Program changes can be named, controls can be named, and can also display on/off, a meter showing approximate position for pedals. It can display tap tempo rate, or even the name of a value for a control - eg. For an Amp model select CC, it can display the model name selected.














=====Features=====
  * **Expression Pedals**
    * Up to 8 Expression Pedals or Pedal inputs (CV / 10k pot)
    * Individual option for pedals to be 'dynamic' by changing the midi messages sent based on the Rig COntrol Patch Change
    * Value scaled between pre-defined min and max values (can also be different for each program change)
    * A MIDI CC can be configured to act exactly as if it were connected to an analogue in (The 8 limit still applies)
  * **LCD Display**
    * Named Program Changes
    * Named CC events
    * Bar Graph displaying value/on/off
    * up to 10 specific CC value name tables for effect selection, etc
    * Tap Tempo BPM display

    * Up to 16 fixed midi output buttons with LED indicators
    * Up to 16 banked buttons for up to 128 midi commands with 16 LED indicators
    * Buttons toggle between a pre-defined min and max value
    * 2 modes for buttons: switching or momentary
    * Bank displayed on 2x7 segment LED digits or LCD (use 2x20 screen for bank display on LCD)
    * Bank Up / Down buttons
  * **Multiple MIDI Devices**
    * Can be setup to control up to 7 devices (1 bankstick required per device)
    * Each pedal or button has it's own device assignment
  * **Rig Control**
    * Internal patches allow up to 32 midi events can be sent at the same time giving you complete control of all you gear
    * Patches can be triggered by any button (PbD only) or a MIDI IN event (PbX only)
    * Up to 8 relays can be used to switch amplifier channels, or other analog switch.
    * Relays can be triggered from patches, a button or a MIDI In event
  * **Gig Control**
    * 30 Song Lists can be setup to trigger patches in a given order
    * Up to 128 patches can be listed in any order
    * Cue Next / Cue Previous can be done from any button or a MIDI IN event
  * **PedalSwap**
    * Allows dynamic pedals to change there midi settings without utilizing Rig Control
  * PC Editor files allows easy...ish customization for different MIDI devices. 
  * Settings configurable from box. (this is a very slow process but can you help you out in pinch, it's far quicker to use the PC Editor). \\ 








=====What's The Difference?=====
Basically Pedal Box is a MIDI Monitor / Processor. Pedal Board is a... well... floorboard.

======Building Pedal Box / Pedal Board======









=====Software=====

Pedal Box / Pedal Board has been written in C for PIC18F4620. \\  
The legacy version for the PIC18F452 is no longer available.


===Current Limitations===  
  * No Sysex Support



























====Installing====
Firstly your PIC must be setup with bootloader and MIOS 1.9 or higher. \\ 
You should be familiar with compliling 'C' files for MIOS. \\ 
As well as uploading files to the Core module. See [[http://www.ucapps.de/]] \\ 
\\ 
You need to upload the PB software, as well as fill the banksticks with the required info. \\ 
\\ 
The first bankstick is used by PB with info about itself (Master Bankstick), the others are used to tell PB info about the devices it is controlling (Device Banksticks). \\ 


USE THE [[pedal_box:pc_editor_manual|PC EDITOR]] to setup and upload the Master Bankstick data. \\ 

You can also see the [[pedal_box:manual]] for more information. \\ 

===Uploading device information===

Device Banksticks tell PB about the MIDI devices it is controlling

In these banksticks:
   * The device name
   * The default MIDI channel
   * The Event Map
      * MIDI event name and event type
      * 128 Entries of CC's, 128 of Program Changes
   * 10 x Parameter 2 value maps
      * Value name and associated value
      * Up to 128 entries each (1 for each value, does not need all entries)

USE THE [[pedal_box:pc_editor_manual|PC EDITOR]] to setup and upload Device Bankstick data.

===Uploading Pedal Box / Pedal Board===
Now we are ready to upload Pedal Box. Browse to your Pedal Box directory and open the pbx_config.h file. \\ 
You need to customise the application here. Comments inside in main.h will tell you what each setting does.

Once you've customised the application it needs to be recompiled. Simply run re-make.bat.

Upload the created project.hex using MIOS Studio (or .syx using MIDI-OX or other midi software) file to the core module. MIOS will now reboot, and that's it!

==pbx_config.h in detail==
**PEDALBOARD** - Set to 1 if for Pedalboard mode, or 0 for Pedalbox mode \\ 
**ENABLE_MIDI_IN** - If you wish to utilise the MIDI IN port, set to 1. Otherwise 0 \\ 

**MIDI_MERGER** - To forward events recieved at the MIDI input
 to the output, set to 1. Otherwise 0. \\ 
**MIDI_MERGER_DISABLE_MASTER** - If the MIDI Merger is enabled, but you do not want to forward messages targeting functions of PB (eg. A patch change) - set to 1. Otherwise set to 0 to forward all messages. \\ 


**AIN_DEADBAND** - //(standard MIOS question)// \\ 
**AIN_NUMBER_INPUTS** - //(standard MIOS question)// \\ 

**DIN_DEBOUNCE_VALUE** - //(standard MIOS question)// \\ 

**DIN_FIXED_BUTTONS** - How many fixed or static footswitches are connected (0-16) \\ 
**DIN_BANKED_BUTTONS** - How many banked or dynamic footswitches are connected (1-16) \\ 

**DIN_BANK_UP** - The pin number assigned for bank up (2-33)\\ 
**DIN_BANK_DOWN** - The pin number assigned for bank down (2-33)\\ 
**FIRST_PEDALSWAP_DIN_PIN** - The pin assigned to the fist PedalSwap footswitch and LED // Be wary that placement does not interfere with Relays or LED Digit DOUT pins// \\
**NUM_PEDALSWAP_BUTTONS** - Number of PedalSwap slots available (max and default = 6) \\ 
**EVENT_SETUP_DIN_PIN** - The pin number assigned for entering event setup mode (while holding bank down) (0-31) //Can not be the same as bank up or down// \\ 
**GLOBAL_SETUP_DIN_PIN** - The pin number assigned for entering global setup mode (while holding bank down) (0-31) //Can not be the same as bank up or down// \\ 
 
**RELAY_SHIFT_REGISTER** - If your using relays, which SR are they connected to //if using SOME LED indicators, chosen SR must be after ALL POSSIBLE indicators// \\ 
**RELAY_LED_SHIFT_REGISTER** - If your using LED indicators for relays, which SR are they connected to //SR should be AFTER the relay SR// \\ 

**USE_LED_INDICATORS** - Are you using LED indicators for each footswitch, set 1 for yes, 0 for no \\ 

**DIGITS_CONNECTED** - Numver of LED digits connected (0-2). Set 0 for none. \\ 
**DOUT_DIGITS_SR** - Which SR is the first digit connected to. \\  


==Example of pbx_config.h setup==
This is an example configured for:
   * 4 expresson pedals, 8 fixed footswitches and 8 banked footswitches. \\ 
   * There are 1 LED digit connected to shift register 3 (start at pin 25). \\ 
   * There will also be 16 LED indicators for the footswitches . \\ 
   * Bank down is at pin 16, bank up at pin 17. \\ 
   * Special buttons for setup modes are the same as the first 2 fixed buttons. \\ 
   * PedalSwap is activated py footswitches connected to pins 19 -24 (LED's on counterpart dout pins). \\ 
   * Relays are located on Shift Register 4 (pin 32), and it's led indicators are on SR 5 (pin 40)

=====Hardware=====






====Minimum Setup====
  * 1 x Core Module (PIC18F4620)
  * 1 x 16x2 LCD Display
  * 2 x 24LC256 Bankstick
  * 1 x CV Pedal / Expression Pedal (or pot)
  * A MIDI Floorboard / HUI (PbX) **OR** 1xDINX1 Module and 4 buttons (PbD)//- Required for editing settings after upload//





====Analog inputs====
<box 170px left grey round>{{mcrozier:ain_trs_connection.jpg}}</box> \\ 
I use normalising (DPST) 6.5mm TRS Sockets. \\ 
Tip = +5 (vd)\\ 
Ring = CV (A#)\\ 
Sleeve = Ground (vs)\\ 


Ring and Sleeve are connected together on the normalising side. \\ 
When a jack is not inserted, CV connects straight to ground (prevents AIN jitter). \\ 
----
|{{mcrozier:pbx_core-trs_connection.jpg}}| \\ 
When inserting/removing a jack, make sure the control voltage = 0 (pedal off). Or you will pass voltage straight to ground, causing mios to crash, and maybe cause damage to the circuit. \\ 

//If your using manufactured expresion pedals or other cv devices, check the pin assignment, some devices use a different setup. \\ 
With different setups, there is no way of stopping +5 being passed straight to ground while inserting/removing the jack (that i know of). Make sure you power off first!!!//



====Buttons / Foot Switches====
Up to 34 buttons can be used with Pedal Board mode. \\ 
16 fixed buttons, 16 banked buttons, bank up and bank down \\ 

This gives a total of 144 possible midi commands.

The fixed buttons must be connected first (pin 0 up to 15), any amount 16 or less if fine (including none). \\ 
Fixed buttons are buttons numbers 1-16. \\ 

The banked buttons connect next (starting from the next available pin), again any number of banked buttons 16 or less is fine (including none). \\ 
They represent buttons 17-144. \\ 

The special function buttons pair up with bank down to access the setup menu's these can be any button aside from bank up or bank down. (pins defined in pbx_config.h)

How many of each type of button is defined in pbx_config.h.

The amount of banks available will vary with how many physical banked buttons you have. eg. with 2, there will be 64 banks, with 4 there will be 32 banks. \\ 
With 6 buttons there will be 22 banks. In bank 22, the first 2 buttons will represent button number 143 and 144, the 4 remaining will also represent 144. \\ 
If you don't have any banked buttons, bank display functions will also be disabled.



====Indicator LEDs====
Buttons can have indicator LEDs displaying their curent status. \\ 
LEDs connect to the first 1,2,3 or 4 shift registers, matching up with their DIN counterparts. \\
eg. SR1 DIN D0 = DOUT D7, DIN D1 = DOUT D6 \\ 

If you do not wish to use indicators for buttons, they must be disabled in pbx_config.h









====7 Segment LED Digits====
2 seven segment LED digits can be connected to a DOUT module for bank display. \\ 
Pedal BoX does not use a LED matrix, each digit requires it's own shift register  \\ 

Connect digits to the shift registers after LEDs, so if you only use 4 leds, still start at SR2 (or pin 8) \\ 
|{{mcrozier:pbx_leddigits1.jpg}}| \\ 

0, 1 or 2 digits can be used (defined in pbx_config.h). If no digits are used, the current bank is displayed on the LCD (requires a 2x20 display)

The shift register of the 1st digit (the one's display) must be defined in pbx_config.h \\ 
The second digit (ten's) will be automatically assigned to the next shift register.

If only 1 digit is used, and bank goes higher than 9. The dot will light up to let you know that '0' is actually 10, '1' is actually 11, etc \\ 

In place of LED digits. A 2x20 LCD Display can be used (instead of 2x16). The last 4 charcters of each line are used for bank display. This will only happen when DIGITS_CONNECTED = 0 in pbx_config.h.

**Buttons, LEDs and LED Digits are only available for Pedal Board mode**






====Relays====
Up to 8 relays can be connected to trigger external switches. Relays can be triggered with a button (PbD), a midi event (PbX) or within Rig Control (both). \\ 
Relays can also have separate indicator LEDs.

Relays connect to any free shift register (defined in pbx_config.h). The relay indicator LEDs are also assigned their own shift register.


NOTE: Be sure that you use free shift registers. Remember if you use LED indicators for buttons, the shift registers taken up by buttons are the same for their LED's. If not all buttons have LED's you must leave the DOUT pin's free on any pin that has a button connected on it's DIN counterpart. \\  If you don't use button indicator LED's, they can be disabled in pbx_config.h, freeing up the DOUT shift registers for use by relays or LED digits.

For information on how to connect relays to a DOUT module refer to the midio128 notes at ucapps: \\ 
  * [[http://www.ucapps.de/midio128/relay_example.pdf|relay_example.pdf]] \\

==== Connection Overview ====
{{http://www.durisian.com/midibox/PB/images/pbd_din_dout_connections.jpg}} 

**Please Note:** Default connections have changed since 2.6. The default has only one digit connected to SR 5. With bank and PedalSwap footswitches and LED's attched to SR 4


Pedal Board Test Bench \\ 
{{http://www.durisian.com/midibox/PB/images/pbd_test_bench.jpg}}






====Where to get Pedal Board parts====
I only built Pedal Box, so I use the Behringer FCV100 Foot Pedal in CV mode. But here's some links that came up on the forum.

  * [[http://www.banzaieffects.com/Pushbutton-Footswitches-Momentary-c-333.html | Banzai Effects]] stock a good range of momentary footswitches - perfect for this project
  * [[http://www.smallbearelec.com/|Small Bear Electronics]] Specializes in DIY guitar sound effects
  * stryd_one offered this google search for momentary footswitches. [[http://www.google.com.au/search?safe=off&q=momentary+SPST+footswitch]]
  

If you build Pedal Board please FIXME









=====To Do - Future Plans=====

  * Allow control of Midi devices without using banksticks. So default numbers only setup is possible
  * Add MIDI filter
  * Add IIC Midi module so feedback can be recieved from the device (if running in pedal box mode with separate floorboard)
  * Probably a lot more. I expect this will be an ongoing project





======Inspirado======

Here's a vision I had: \\
