Yes, though multitrack is too confined a concept probably, since parallel 'tracks' seems to suggest they have the same length. 'multi loop element' is closer to what I was thinking (but there may be a better term for it).

> You want the ability to play loops of different lengths simultaneously then?
Yes. Essentially each loop element loops on its own length, but is linked to its peer loop elements within a composite loop (or group of loops, or 'gloop'). Having them linked would enable things you can't do with just multiple disparate loopers, such as the beat ratio sync thing.
The other unexplained thought, pitch shift while recording, would go something like this: I record an audio stream into the loop (guitar is my point of departure) but I'm also feeding the MIDI notes underlying that audio stream (in my case from my guitar synth). The looper 'applies' this MIDI sequence of notes as the basis for pitch shifting (while recording). You've now fed the looper 'knowledge' about what's supposed to be in the audio stream as far as pitch is concerned. First order, you could tell the looper to flatten the pitch back out. Or, have it play the inverse melody (inversion as in counterpoint / fugal variations etc). Or, apply modulations such that one could manipulate loops as malleable compositional elements (force it through chord progressions). Hugely unpractical, therefore highly likely to be fun...
