Basics Section Quick Guide Reference ● AMP (Amplitude) In PAGES 23 to 31, you can set the volume of each Element after the OSC (Oscillator), PITCH and FILTER parameters have been applied, as well as the final overall volume of the signal sent to the outputs. The signal of each Element is sent at the specified volume to the next Effect section. Also, by setting the AEG (Amplitude Envelope Generator), you can control how the volume changes over time. n The final volume for all Elements is set in the Total Vol (Total Volume) parameter, Common Edit PAGE 2.

When you play a key, the volume goes to the Initial Level, at the speed set in Attack Rate. From there it goes to the Decay and Sustain Levels, at speeds set in Decay 1 and 2 Rates, respectively. When the note is released, the volume goes down to zero, at the speed set in Release Rate. In the illustration below, the letters a - d indicate the respective Rate (R) settings for Attack - Release. The greater the value for each Rate, the faster the filter goes to the next set Level - in other words, the time it takes for the volume to change (between Level settings) becomes shorter. Velocity Sensitivity and other parameters can also be set if required.

The level (Y-axis in the illustrations below) is a different aspect of the sound, depending on which EG is being used. For the PEG, level corresponds to Pitch. For the FEG, it corresponds to the cutoff frequency. For the AEG, it corresponds to the volume. The behavior of the EG over time is controlled by the Rate (R) parameters. Rate refers to the time it takes to go from one level to the next (for example, from the initial level to the attack level). The illustrations below show how different Rate settings affect the sound. To extend the time between level changes and make it long, set the Rate (R) to a small value. Attack Level Level Attack Level Level Rate (R) is set to a large value. Initial a Level Rate (R) is set to a small value. Initial a Level 0 Time Attack Time is short. 0 Time Attack Time is long.
