Bob already answered the question about loop linearity on the Looperlative but I also wanted to chime in a little about the use of parts in a looping device. Essentially, the salient reason for creating separate tracks for separate parts in a song form is so that we can then manipulate them after the fact (or treat them with effects in real time, separately). What I find (and I did a show tonight where I played drumset, percussion, found objects, fretless bass, trumpet, melodica, strumstick and voice and in more of a song oriented rather than the more experimental found sound shows that I usually tour with) is that one doesn't usually have time to layer 8 parts onto one section of a song........................ ..........it just takes to long to do so and you begin to lose your audiences attention if you don't create your song structures more quickly. So, by this, what I'm getting at is that, since it is always incumbent upon us (unless we are specifically creating noise types of experimental work) to create parts that are timbrally separated so that the phenomenon of 'timbral masking' doesn't occur, it becomes efficacious to just overdub new instruments onto an existing track and not worry so much about being able to take those parts in an out when we switch from a verse to a chorus section of a tune. So, even if the Looperlative were able to create two sections with 8 separated parts each (which it actually does I suppose since it does create 16 potential mono tracks and clever routing and muting might be able to exploit this fact) you probably aren't going to need that many tracks in creatiing a song. That is, unless you are doing a building song in the manner that Mir O did at the Y2K6 Live Looping Festival. In Mir 0's brilliant approach, his song built and built and built and took almost 30 minutes to perform. If one is performing pop or folk styles of songs, you just want to get your sections created a lot more quickly than that and I'd never want to use 8 separate loops. I'm curious and will start a new thread to poll this: I wonder how many tracks people use in a multi tracking loop situation?
