I'm interested to hear how you get on with your 1600.
Post up a thread for any tips, techniques or tricks you use. It's good to hear another users ideas and experiences.
I'm working on my own so the loops,drum machine and bass machine are really usefull. I've also got hold of some of the M-Audio Pro Sessions drum loop disks. They've got some really good sample loops in a variety of styles. I've been finding the 'scene' function really useful at mixdown ~ it's great to be able to programme changes for track volumes, panning, eq, delay, reverb, compression etc.
I havent got a handle on mastering yet but I've found the mastering presets to be good anyway so aside from setting the occasional fade-in or fade-out I havent ventured into editing the mastering settings. Regards
