Synthesis and Envelopes



I'm pretty disappointed with what I came up with this week. It is a failed attempt at granular synthesis. I thought that the Dust object would work differently than it it. I didn't realise that because the the pulses in amplitude were random you cannot reconstruct the waveform with a higher density, but loose shape to the waveform altogether.
