I did a few experiments, first I reduced the cache from the default 10gigs to 1gig. Then proceded to load mp3's into the clip view where they started to decode. I managed to get 13 files in, these were longish house tracks of around 7-8 minutes average. On trying to load the 14th an error message come on screen saying there wasn't enough room in the cache to decode it and advising to change the cache size in the preferences section. Well, you can't do that in the middle of a gig.
I totted up the time of these mp3's and they worked out roughly to be 1hour 45 minutes to try and work out what was the minimum size for an average gig. At a rough guess 5 gigs will give approx 9 hours.
I also discovered that once the cache is full and you get the error message, you can delete any of the tunes in the current session and then decode another mp3. Important to know this if you're in the middle of a gig.
If you close the current session and open a new one, and you then go to decode different mp3's to those that are stored in the cache, the files in the cache are automatically overwritten.
Hope you find this useful.
