I am interested in building a custom USB device utilising AVR in order to control music software such as Ableton Live. My project is still in the planning phase.
I have a reasonable understanding of how to assign external controls to Ableton. However, my question is how do I get information out of packages like Ableton in order to drive custom LEDs and other display elements on my custom controller ?
Sorry if I have posted this in the wrong place... or even on the wrong site. I thought here might be a good place to start.
Any help would be gratefully received.
Edit... I was looking for responses from people that actually had experience in this area; not theorise, point to help-me links and otherwise obfuscate any productive contribution; hence the post in general electronics. I thought that would be intuitively obvious, but it wasn't. Thank you for closing this topic before taking any real consideration of the requirements of the original poster.
