My first attempt was gated and reverberated, shaping a composition of increasing snippets from the loop. It worked well with the bell-like chimes from a recording made at an art-making session on the north coast of NSW last weekend.
The video shows Mike and Keith tapping steel canisters to produce the tones.
My second attempt concentrated on using a filter to shape the frequencies of the recording, sliding from low to high to low again as reverb feedback increases. This produced a fade in, out, in and out again while the reverb has a descending feedback.
