I know it's a chunk of extra work, zuki, but if you are going for a mono rig for a while, you MIGHT consider re-tweaking your registrations so they work better in mono. You've already noticed that stereo pads and effects, etc. get perceived quite differently in mono...

If you go through your setups, and re-tweak them to correct for what gets lost, then save that whole set as a 'Mono Set', you may not get so discouraged with having to go mono (plus you'll still have a set tweaked for stereo when you go back to that).

Not that that should stop you from getting that second Compact ASAP...
