It's possible that a major reason I purchased M4L was to finally have the ability to customize the APC40 - which surprisingly is a very limited tool. However I'm not learning M4L as quickly as I'd like. All the tutorials (several) I've gone through address the basics but I'm looking to jump to the chase to focus on customizing control surfaces. I finally found this - http://vimeo.com/8956091.
So my knowledge stops there.
Can anyone recommend tutorials of any kind on customizing control surfaces? The APC40 specifically though I'm interested in any broad instruction as well. The depth of Max still seems obfuscated to me but maybe i just need to continue going through the accompanying tutorials. Thanks in advance.
