These are the row of knobs to the right on the Main Panel. All of these knobs change the values of various parameters in the remote editor panel and affect all loaded samples. Thus they can be used for quickly adjusting the overall sound.
The knobs are bi-polar, which means that when they are centered, no parameter change is applied. By turning them to the right you increase the corresponding value, and by turning them to the left, you decrease the value.
Again, the movements of these parameters can be recorded as automation. This is done just as with any other automation recording, as described in the chapter "The Sequencer" in the electronic documentation.
The controls are, from left to right:
These two knobs each control a parameter of the filter on the remote editor panel. Note that the filter must be on for these to have any effect.
This changes the cutoff frequency of the filter.
This changes the resonance parameter of the filter, meaning - the filter characteristic, or quality.
These three knobs control the Amplitude Envelope on the remote editor panel in the following way:
This changes the Attack value of the Amplitude Envelope. That is, how long it should take for the sound to reach full level after you press a key on your keyboard.
This changes the Decay value of the Amplitude Envelope. Decay determines how long it should take for the sound to go back to the sustain level after it has reached full value and the key that triggered the sound is still being pressed.
This changes the Release value of the Amplitude Envelope. Release works just like Decay with the exception that it determines how long it should take for the sound to become silent after the key has been released.
