The top of the Envelopes tab shows you a visual representation of how the harmonic envelopes are currently set.
It’s basically a spectrogram, but cleaner and linear scaled. Optimized to make more sense when tweaking patches. The essence is the same: it shows you how your note will evolve over time. Brightness indicates loudness.
The colors here are the same as on the Volumes page — purple for the lower harmonics, going through blue and orange up to red for the highest harmonics. Time is the X axis, and the background is segmented into units of 1s.
Note that the volumes from Page 1: Volumes are reflected here.
Remember! All harmonics in sine machine are scaled to 1/f to help you make things that sound good to humans — so the harmonic brightness is actually relative to this 1/f scale.
If you were to run sine machine through a spectrogram, you will see a lot less brightness showing on the upper harmonics — they are quieter absolutely, just like every naturally occurring sound and instrument.
