Thanks Billy. I've previously tried experimenting with tape loops. By more adventurous, I was thinking along the lines of something that wasn't limited to the confines of a cassette. Such as those huge reel to reel loops you see that stretch from one end of the room to the other. Guess that's probably never going to happen with something as fragile as casette tape though.
just because it is not commonly done, doesn't mean it is impossible. give your ideas a shot and let us know your results!
you are not alone in this impulse. i have a bunch of cassette recorders i got for free from a local school that i plan on combining to create a lofi looper at some point (when i have time to play with possibilities). i think there is potential there, it just needs to be worked out. of course i'll share any ideas or tips when/if i encounter them.
i do agree the fragility/thinness of cassette tape will be a problem here... but hey, a lot of interesting things can happen when you are right on the edge of things falling apart. there ends up being a tension and urgency about the process as a result that i quite like.
