| OpenDeck is hands-down the most robust DIY MIDI contoller platform available. I've used it to build mixing console controllers for my DAW, dedicated look-alike hardware controllers for my favourite software plugin emulations, and more. But there was one thing I wished it could do even better: integrate with guitar amplifier and effects similuation software like IK Multimedia's AmpliTube. |

Spelling change needed: simulation

| However, for many guitarists, the real power in AmpliTube is that it also supports up to 128 user "presets" when in "Live" mode, each defining a unique combination of virtual pedals, amplifiers, cabinets, and rack effects, and all with pre-programmed parameter values. In other words, you can store up to _128 distinct virtual guitar rigs_ and recall each with a MIDI Program Change message. At first, that might seem like overkill, but I routinely use 20 or more such presets in a single night's performance, and often 3 or 4 presets in a single song. | ||

| The trick in building a controller for this purpose is balancing functionality with usability. I certainly don't want a controller with 20+ foot switches on it; while perfectly functional, that's not particularly usuable and it's larger than it should be, in my mind. Just imagine the cover band guitarist that would need 50 or more different foot switches for their setups! |

| - AmpliTube logically organises presets in groups of 4. So, my controller has 4 _Program Change_ foot switches, numbered 1-4. In the Configurator, these are _Buttons_ with _Message Type_ set to _Program Change_, and their values are 0-3. _(I know, it's a little confusing: AmpliTube presets start at 001 in its UI, but PC#0 for Program Changes. So, PC#0 recalls preset 001, PC#1 recalls preset 002, and so on.)_ | ||
| - The _Program Change Offset_ UP/DOWN foot switches are configured for the new [_Program Change Offset Increment_ and _Decrement Message Types_](https://github.com/shanteacontrols/OpenDeck/wiki/Configurable-features#message-type). The value can be anything from 1 to 128, but I have 4 _Program Change_ foot switches, so I set the value to 4 for both the UP and DOWN foot switches. Pressing the UP button adds 4 to the current offset value, and pressing DOWN substracts 4. The offset cannot go lower than 0. |

Spelling again: subtracts.
Ugh. Embarrassing.

Thanks a lot!
I'll merge this then, in that case.
You can just push changes to the branch. |

OK, but fair warning: I am on summer holiday from tomorrow through late July. It will be about a month before I can complete it. |
No problem. Enjoy your holidays! |

This is harder to explain than I expected, so you might find it too long. Use all of it, or use none of it; I won't be offended 😉
I've never used GitHub blogs, so I'm not sure about formatting, relative links, etc. Please correct as needed, and tweak title, tags, etc. as you see fit. Basically, it's your site, so change anything you like.
When I get the actual controller completed, I'll send a pic.
Cheers!
