diff between application and and composition midi mapping?

[sebern]

Hello all my name is rudy and im a bit of a noob when it comes to vjing...i recently purchesed resolume 4 arena and an apc 40...mapping is coming along slowly but surely and im learning as i go....i was wondering if anybody could tell me the difference between composition midi mapping and application midi mapping, also i have seen people talking about a a bomes patch...looks super cool on you tube..but again i am new to this...so at this point that seems impossible for me to do =/ thanks in advance for your time and help =)

The difference between app and comp mapping is actually explained in the Keyboard mapping chapter of the manual:

The Application Map is used by all compositions. In Application Mapping, you can choose between Deck and Layer Focus. Keys set up in Layer Focus will change what they control depending on what is selected. For example, if you set a key to clear a layer while in Layer Focus, the currently active layer will be cleared when you hit that key. You can then change the active layer and clear it with the same key.

Deck focus is different in that the mapping is absolute, so every layer can be cleared with its own key.
An exception is made for mappings applied to the Clip tab. These are always context dependent, meaning that the same keys will control the same functions on all clips. regardless of whether they were mapped in Deck or Layer focus.

Tip! This way you can for instance set and trigger the cue points of all clips in your deck with the same keyboard shortcuts, without having to map each one individually. By default, the QWERTY keys will trigger cue points, pressing these keys while holding down SHIFT will set them.

The Composition Map is saved along with the composition. Keys set up in this map affect particular things. For example, you can set separate keys to clear each of the layers - each key will only clear the layer it is assigned to.

The secret to good keyboard control is to combine the Application and Composition maps together so you get control over the specific things that you need through the Composition Map while also maintaining some flexibility with the Application Map.

Bomes is great to get specific functionality out of the APC, but to get started you can try the attached template, which can be used with Resolume out of the box.
