Trying an idea from David Linton, who asked, What if you mixed all your oscillators, tuned to the same pitch, in one patch.  I didn’t use all 15 of my 1V/octave music VCOs in this mix, but just 10, each followed by a separate VCF with a fixed cutoff.  During the recording some waveform changes were manually made.  The name comes from the fact that the whole piece is ‘enveloped’ by manual attenuation.  This is a short recording.  If I did it live, I would probably stretch it out.
