I was not aware the JM was able to play its various Before we get too far with this, lets try to define some terminology. We had to do this when we started thinking about these ideas at g-wiz long ago: Loop - a potentially complex set of media data, repeating in some fashion in time. A "Loop" can contain one or more "tracks." The tracks repeat in some relation to the loop repetition rate, and may all be synced together in equal lengths or have complicated time relationships to each other. Any looper, no matter what it's features, would only play one loop at a time. When we talk about multiple loops, we mean things that are discreet from each other in time. So you might switch from one loop to another, but you wouldn't play two at once. If you did, you would still have one loop, but it would just have more tracks. Got that? Track - A singular set of media data, available to be repeated in some fashion within a "loop." A track can be operated on with the various loop functions we have available. So the echoplex and jamman have multiple loops, but really only use one track at a time in a loop. Some of the functions give the appearance of multitracking, like overdubbing on both of them, and multiply and undo on the plex. Then there are all sorts of things that can happen in a multitrack environment. Grouping, copying, different processing on each track, defining relationships between tracks, etc. Really a whole new set of performance functions. How you put all that in a usable interface, that makes sense for real-time, live usage, is the tricky part! kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@annihilist.com | http://www.annihilist.com/loop/loop.html http://www.annihilist.com/ | Loopers-Delight-request@annihilist.com
