Some more purposes to use groups for: - When combining instruments it comes in very handy. I often do that to get fat layered sounds. But well, often one instrument is too loud, so I might want to reduce the level. Pretty much a timeconsuming job when doing that for each zone. But because I almost allways have all my zones assigned to groups (which will automatically be copied with the zones) I can just alter the level of the groups. - I often use two (or even more) layers of the same zone (again to get a fatter sound), just that I might detune the doubled zones. These can now be panned and levelled easily using groups. I wish there was a tuning parameter directly on groups, would make such jobs way easier to accomplish. Or well, editing of multiple zones would just do the same... I hope this will come soon. - Filter and ADSR offset. Only available for groups. Pretty great to get more interesting sounds. I might use one layer plain while another layer will run through some Filter/ADSR offset. Regards, Sascha
