Yamaha DX 7 - envelopes

The envelope generator will determine how the volume (amplitude) or timbre (tone) of a note will vary over time.

What is impt to know is whether the envelope is being applied to a carrier or a modulator operator.

Envelope modulation of a modulator will effect timbre.
Envelope modulation of a carrier will effect volume.
(this is kind of like envelopes applied to filters vs VCAs in subtractive synths)

The parameters that determine the shape of the envelope are RATE (R1 to R4) & LEVEL (L1 to L4).
The Rate parameters determine how long it takes the envelope to reach each level.
Each RATE and LEVEL can be set from 0 to 99
Each operator can have a unique envelope.
