How Does It Work
How Does MIDI Routing Work With MIDI Designer
How do presets work? How do layouts work? How can I save my stuff?
Presets
Presets represent all the values in your entire MIDI Designer setup. For example, a knob called “Sweep” might be set to 45° (or an outgoing MIDI value of 32). When you store a preset, that value is saved. When you recall a preset, all controls snap to the value they had at the time the preset was saved. So your sweep knob would snap to 45° regardless or what position it’s in, and that value would be sent out to all hardware/software that is connected.
Presets are available from the main tongue that drops down from “More” for both save and recall. Presets cannot be deleted at this time, but they can be overwritten.
Layouts
Layouts represent the whole of your MIDI Designer layout: all banks, all pages, and all controls. Setups are files that have the extension “mididesigner” so an example would be, “Cannes May 2012 05.mididesigner”. MIDI Designer adds the file extension for you.
Layouts may be saved, loaded, and emailed. Find this functionality under More -> Config -> Actions.
Layouts may also be opened from email. Follow the default instructions in the email which contains the layout.
In addition, you can drag and drop layouts to and from MIDI Designer via iTunes.
Note: layouts contain your presets, so if you open your layouts on another iPad, you will find your presets are also available.
In Design Mode, when I select a control and the quantity I want, I get double what I asked for. If I want one slider and select that option I get two. If I select 4 I get 8. This is a bit confusing. How can I get only one set of controls?
You are most likely looking at the same bank and same page on both sides. The page selectors are at the top and look like tabs, and the bank selectors are the little numeric things that say “1” at the top of either side. See the pic below.
Pages exist in banks, and you are free to show the same bank on both sides and even the same page (useful sometimes in Design Mode).
To stop this from happening, switch the page on the right side (or left side). Alternately, you can switch the banks to be separate on the right and left sides. If you do this, you would have two different numbers showing at the top (1 and 2, for instance), and each side could access totally different pages.
Note: you can add and remove pages and customize them (color, texture and name). You can also add and remove banks.

How do channel changers work?
I’ve noticed that there’s a type called “channel changer” for knobs, sliders and crossfaders. What’s it about?
