What are the four different types of envelopes?
Amplitude: The amplitude envelope controls the volume of the note or amplitude of the waveform. Pitch: Controls the pitch of the waveform. If the waveform is of the hand drawn variety the values correspond to the following (assuming 1.0 is the highest value and 0.0 the lowest): 1.0 – One octave higher. 0.5 – No pitch change 0.0 – One octave lower. If the waveform is from an imported file: 1.0 – play 3 times faster. 0.75 – play 2 times faster. 0.5 – play actual rate. 0.25 – speed is zero, no sound produced. 0.0 – play actual rates but backwards. Cutoff: Specifies the cutoff frequency. I don’t know what frequencies the actual values correspond to. The lower the value the lower the cutoff frequency. This envelope is used by the next envelope. Freq Ratio: This envelopes controls the ratio of hi-pass to low-pass filters. The cutoff value of the filters is controlled by the cutoff envelope. A value of all blue means 100% low-pass and a value of all red means 100% hi-pass. If the value is hal
