The Dave Smith Instruments Prophet '08 Pot Edition 8-voice analog synthesizer offers an alternative with 38 of the 52 front panel parameters controlled by pots (potentiometers); rotary encoders are still used for the remainder of the controls.
The Dave Smith Instruments Prophet '08 Pot Edition is exactly the same as the non-pot version. The difference is strictly in the controls themselves. Encoders are endless, they have no minimum or maximum limit. The advantage to that is that when you edit a preset parameter, the change begins at the preset value and increases or decreases, depending upon the direction turned.
Pots typically have about 270- of travel and have definite limits. The advantage to that is that you know, by feel, where the minimum and maximum limits are and you can sweep through the entire value range in less than one full turn.
The Prophet '08 PE features 3 edit modes for the pots: Relative, Passthru, and Jump. In relative mode, the value change is relative to the preset value. In passthru mode, turning the pot has no effect until after the edited value equals the preset value (that is, until the edited value passes through the stored value). Jump mode uses an absolute value based upon the position of the pot when edited; turn a pot and the value jumps immediately from the stored value to the edited value.
