Cubase LE stats (the ones that matter):
48 mono or stereo tracks, just tried this in version 4 it will not let you add more than 48.
Le1 and Le4 only let you record 8 tracks at once, Le5 lets you do 16. I'm going to assume the limitation applies to outputs as well.
Le1 only let you have 2 inserts, le4 lets you have 8, and LE5 allows... I dunno probably 8 as well.
Le 4 has 8 sends per track (don't remember what LE1 had and not used LE5)
Quoteing
Steinberg:
"While previous versions of the routing system included some restrictions, the new routing capabilities allow totally unlimited routing between group channels regardless of their order, and supports sending from groups to FX returns as well as from FX returns into group channels"
Le4 got rid of the VSTi rack and that was really junky (I hate instrument tracks), so I really hope they put that back in on 5 (I have only used LE1 and LE4).
Of course LE is really limited. Reaper is an awesome DAW no doubt if you can stand the work flow of it.
