The E 5000 has it all . For instance sampling has never been so easy.
The E 5000 has a large screen, where you can edit loops in a short time . My friend (who works with AKAI) once tried it for an hour as he went to the shop buying one ...
The Emu lets you determine the tempo and control of any sample that has a steady beat (not only drum, guitarlicks etc...)
I once had to resample a loop (it took me about 20 seconds) from 127.3 BPM to 130 BPM.
The Emu can load sounds very quickly, (from an internal harddisk). If you load from ZIP drive it takes you 1 MB / 1 sec.
