I think LE will be more then enough to learn on as it provides pretty much all the features of the full version except a few ones for me which arent a huge deal for a basic DJ setup to learn on. (comparison chart here: What’s new in Live 12 | Ableton)
only 2 sends
no tempo nudge (thus impossible to use in combo with a TT)
Only 12 effects
only 2 VSTs
Only 8 scenes per project
Pretty much none of these would be an issue in a basic ableton DJ setup (in fact in my hyper-minimal setup none of these bar nudge are an issue), once you get into it you will probably need to upgrade (especially the VST issue) but to learn on its definately sweet imo. In fact nearly better as it stops you going crazy with heaps of stuff ;]
In saying all that THIS is the main reason to buy Ableton LE!
You get the ENTIRE cost of LE off the full version when you upgrade therefore there is absolutely no reason for you not get get a copy of LE now and just upgrade later on :] (tho ableton 8 will be out soon and ableton 8 LE wont be out for a while after that and I dont know what the upgrade deal will like like to get from 7 LE to 8)
Ah you get the entire cost off, then its worth it to buy LE then the upgrade down the track then - i was under the impression it cost more but i must have been thinking about something else. Personally i couldnt live with only 2 sends 12 effects, 2 Vsts and 8 scenes
