Hmmmm - I know where you're coming from Diki (you're obviously more resourceful than I am!), however I run in Stereo always (I'm a big believer in it) so using a full loop I would want stereo for percussive elements(panning), and Quality (even Live).
I guess I could use individual hits as a mono sample (a Kick sound for example).
Actually, I'd be happy to get by with just a few mono Kick samples at first to use within a Midi (Heavy "Club" Kick, Delayed Kick, Heavily gated kick etc etc).
If I could get away with THAT, then that would be a nice little memory saver - thanks for the idea!!
