For my theme I'm working on I want to make a mixer that I can control the record levels for each channel (I'm a musician, and use my computer for all my recording). Does anyone know if lsslider can do this? I know you can control any of the playback channels... also please note that I haven't made an attempt yet; just trying to get some info before I waste a day trying to implement this.

i don't know for certain. never messed with it. but on a side note ...

it's never a waste to try something out.
